HP OfficeJet Pro 8500 half recognized

I just got a (wired) hp 8500, and plugged it into the USB port of an Airport Extreme. It works with a MacBook Pro connected wirelessly to the base station, but not with a G4 connected wired-ly to it. In fact, the OS X 10.4 G4 freezes whenever it's asked to print something, even though it acknowledges the printer.

I'm answering my own question, as it may be useful to others. Turns out that the Mac software that HP bundles with the printer is out of date. After contacting their support desk, they provided a link to download the correct printer drivers.

HP Officejet Pro 8500 Wireless that has stopped being recognized as powered on

I have an HP Officejet Pro 8500 Wireless that has stopped printing. Troubleshooter identifies that the printer is not powered on, when indeed it actually is powered on. I have tried unplugging the printer and resetting the network information as well as rebooting my computer all to no avail. The printer is being recognized by the network without any issues, just for some reason it doesn't think it is powered up. I very much appreciate and thank you in advance for any information and advice.

Hello there! Welcome to the forums @margarethpayne
I read about the scanning troubles you are running into with your Officejet 8500 Wireless, on 10.6.8. I have some ideas that could help.

HP Officejet Pro 8500 : Use scanner without print heads/cartridges

Hello.
I have a HP Officejet Pro 8500 (CB023A) that I bought specifically because of the automatic duplex scanner. Buying a scanner with automatic duplex instead of this multifunction printer was out of the question because the cheapest one costed over ten times more than this multifunction printer (and they still do).
I can no longer afford to keep buying print heads and cartridges just to use the scanner, as this multifunction uses ink for scanning!!! But that is beside the point.
I have read in other posts about taping sensors but I was thinking about going a little further and completely remove the printing part of the multifunction. Anyone knows if I can just disconnect the printing part from the circuit board? Or will I have to fiddle with software? Maybe some hidden option in the "Mfg Commands" (accessible by pressing * and # with the printer on) or some other hidden feature?
Considering that this multifunction takes way too long to boot because of all the print head checking/cleaning/etc, with a little luck, without the printing part the boot time will decrease to almost nothing .
Before I start disassembling I would appreciate some advice, specially if someone else has already tried it.
Thank you in advance.

Hello kamath27. Thank you for your reply.
I apologize for not replying sooner but I wanted to try and disassemble the multifunction before replying instead of just replying with an acknowledge.
Also, sorry for such a long post but I wanted to be as detailed as possible.
However, before describing what I did and found, I want to clarify something.
With the multifunction in the same condition it came from the factory, if I remove one print cartridge, or one is empty, the multifunction stops on boot with a message requesting to change the cartridge before continuing and there is no way to bypass it. When this message shows, pressing any button on the multifunction or the screen yields no result (there is no OK button displayed on the multifunction screen). It was always like this and firmware updates never solved it.
And going to the printer control panel on the connected computer says that the printer is offline even if it is connected through USB and is displayed in device manager as a connected USB device. This is the reason why I had spent so much money buying ink that I do not use. I never print anything on this multifunction. All prints that the multifunction ever performed were a dozen or so of maintenance align and test pages.
Now for what I did. I disassembled the multifunction just enough to take out the main circuit board, the wireless board, the buzzer and the door sensors. I set up the printer half and the scanner half side-by-side with the main circuit board in the middle, reconnected everything and turned it on in order to test if anything stopped working during disassembly. Everything was OK and the multifunction worked as normal (printed a test page and scanned it to the computer).
Next, while facing the main board the same way it would be faced while mounted in the multifunction, I started disconnecting the connectors (except the ones that belong to the scanner half) one by one from left to right in the following fashion: With the multifunction OFF, I disconnected one connector, turned the multifunction on, waited for any message or the main screen, tried to print a test page and then scan it, and finally disconnected the multifunction, reconnected the connector and moved on to the next one.
The results were:
- disconnected the tray feeding sensor -> Allows to boot with a paper jam message that can be bypassed with an OK on the screen. Can not print because of the alleged paper jam but can scan.
- disconnected the pump -> Allows to boot but a message keeps popping about pump motor stalled. Can be bypassed with an OK but pops right back and all jobs get aborted. Can not print or scan.
- disconnected the printer motor -> Oddly, no messages. Allows to boot and scan but not print. This was strange because when trying to print there is no message in the printer and the software on the PC only said the printer was busy. I would think the printer would eventually display a message saying the print carriage was jammed or something but nothing happened after 10 minutes. I might test again later as one test may be interfering with the next.
- disconnected the print cartridge door sensor -> Stops on boot with a message to close the door. Does not allow to print or scan.
- disconnected the print cartridges connector -> Stops on boot with message to replace cartridges. Does not allow to print or scan.
- disconnected the print heads connector -> On boot briefly displays a screen with the image of the power button and the code "C00E0060" below. Then the screen turns white and all buttons on the multifunction start blinking. It is as described here but resetting the multifunction, reconnecting the connector and turning it on took it back to operational condition.
- disconnected everything except for the scanner connectors and the tray and door sensors - Gives the exact same behaviour as the previous test (code "C00E0060").
So, from the tests it seems that I can not use the scanner if anything from the printer half is disconnected. Any ideas on how to circumvent this, if possible?
Thank you.

HP Officejet Pro 8500 A910, 2 sections different paper size, prints incorectly

I have an HP Officejet Pro 8500 A910.
My Word document has 2 pages in 2 sections the first page and section is an envelope and the second page is a letter. On the 8500, if I choose to print just the 2nd page (the letter) it uses the envelope paper size and print half the width. Tried Word 2003/2007/2010 same thing.
This prints fine on an BusinessJet pro2230

Hi monkplayer,
It looks like your problem is solved? There wasn't a problem with the printer itself, just the printer settings on your Mac?
This is good information though. We don't always have detailed solutions for customers that are using Safari, since it is hard to write instructions for the general public with specific steps for each operating system.
Best of luck,

Alignment failed Officejet Pro 8500 Premier

Hi,
I own a HP Officejet Pro 8500 Premier and the problem begun while printing a color document. The yellow disapeared. It's been about a month I changed all the ink cartridges. I use the printer regularly but not on a heavy usage. (about 7000 pages within 3.5 years)
I then tried to clean the printheads, align the print heads but still no yellow.
I then opened the cover to see if the tubes were well connected. I presses the star buttom to make the printheads possible to be seen. It's hard to see but I noticed air bubbles in the yellow tube.
I then closed the cover and the printer begun a printhead alignment. Before it finishes, the message align failed!. I pressed OK
the printer looks like crazy Can't do anything. It still entering in printhead alignment mode ending with the alignment failed message. Half the color cartridges has been consumes in these processes.... at 40$ each!!!!!!!!!!!!!!!!!!!!
Do someone see anything I can do?
Thanks

Hi
Finally exited from alignment process but almost no yellow left in the brand new cartridge and still no yellow printed on paper.

Scanning Problems with an HP OfficeJet Pro 8500

I have an iMac running the latest version of Snow Leopard. I have had the HARDEST time, since purchasing my iMac in Dec 2010, scanning documents with my HP OfficeJet Pro 8500 printer. What happens is usually one of two things: 1) Only half of the page fills the scan window, or; 2) The entire document fills the scan window BUT the SCAN button is greyed out so that it cannot be selected!
Yes, I have done the whole delete the current printer drivers, get the drivers through Software Update, reset the printing, etc. None of that has worked (well, on occasion it works for a while). I am not using the drivers that came with the HP 8500; I'm told that you should use the drivers from Apple Software Update.
I have discussed this with Apple Support. They say I need to purchase Apple Protection Care for them to address this. This is weird, considering that this appears to be a software problem with software supplied by Apple!
Any help would be appreciated.
Thanks,

Hi,A phone cable connection to a landline is required for faxing. Generally, a wireless connection only refer to the connection with a computer for printing and scanning, it do not refer to a fax setup. Regardless, the specific device does not support any wireless connectivity but only a wired network or a USB. Regards,Shlomi

Installing OfficeJet Pro 8500 Wireless on Windows 7 laptop with no network

Just purchased the OJPro 8500 Wireless and am trying to install on a new laptop with Windows 7 installed. First the CD that came with the printer didn't like Windows 7, so I downloaded the latest drivers from HP and things started happening... but no cigar.
I'm trying to connect the printer to a laptop using wireless<-->printer, there is no wireless network involved. The equipment is as follows:
- 3-IN-ONE HP OfficeJet Pro 8500 wireless
- Laptop MSI CX600 series with wireless/bluetooth
I would really appreciate any info on how to accomplish this.
Thanks.

1st, thx for clue about ad hoc (wireless) NETWORK (on pg. 10 & 11) in hp OFFICEJET "Wireless Getting Started Guide".
Windows 7 HELP & HP Solution Center were both pretty useless.
(Specifically)
Type "ad hoc" in Search Programs & Files (under START icon).
Results will be; "Set up an ad hoc (computer-to-computer) network". (Click on this)
Results will be; Dialog box to give name to network & set security, then SAVE.
NOTE: My Officejet Pro 8500n recognized "Security Type" = "No Authentication (Open)" & "Encryption Type" = "None"
(Go to)
Control Panel > Network and Internet > Network and Sharing Center > Connect to a network
Results will be; (in Dialog box for "Open Network and Sharing Center") a listing of your ad hoc network name & message (in bold) "Waiting for users"
Finally, on Officejet Pro touch screen, Select "Setup Menu", "Network", "Wireless Setup Wizard", [Name] (given to ad hoc Network in Windows 7), & OK.
(Opps, 1 more thing) Also, follow instructions on pg. 10, to "Change from a USB connection".

Constant Printing Restart on a networked HP Officejet Pro 8500 A909N Series printer

Hello,
I'm curious if anyone has run into this problem before. I have a HP Officejet Pro 8500 A909n Series printer that I have setup as a network printer. This has been accomplished through a print server.
I installed the printer's drivers based upon the cd that came with the printer, in the box.
The problem is that whenever a user prints, say it's a simply one page document... the printer will repeatedly print that single page until it runs out of paper. I have stopped/restarted the print spooler. I've rebooted the printer and the print server. I have deleted the drivers and readded them. I've tried installing drivers from HP's website and then installing those. I have attempted to delete the printer from the server and start from scratch.
When I monitor the print queue, I can see the service restart after each document prints. I can't figure out how to get this to stop.
Does anyone have a suggestion; or has anyone run into this problem? I'm not sure which forum to put this in. I chose the Networks/Wireless forum, even though this is running on a wired network with wireless disabled.
I certainly appreciate any asistance.
-Craig

It ended up being an issue with the port. I had used the same port as the last HP printer that I replaced. This printer needs to run on a TCP/IP port, and not an HP port.
Problem solved.
Oh, and it was wired, with wireless disabled.

HP Officejet Pro 8500 A909a won't let computer boot up

I have an Officejet Pro 8500 A909a series connected to my HP computer running Windows XP Home. It was
working perfectly. Now it won't let the computer boot while it's connected to the computer. I can unplug the
USB cable from the computer and it boots fine. I can then plug the USB back in and the printer prints fine. I
ruled out bad USB ports as everything else USB works fine in the same ports. I put a brand new cable on and
had same results. I rebooted the printer and computer, with same results. I uninstalled the printer and drivers and
reintsalled with same results. Computer freezes at the screen where it askes you to use the up and down arrows
to select OS or wait for it to count down to 0. With printer unplugged it boots perfectly. This just started about
4 days ago. New printer. HP Support was at a loss when I did the live chat. Can anyone help?
Message Edited by ComSource on 06-15-2009 07:14 AM

Hi,
The problem seems to lie in the installer, which has an unusual bad behaviour. The installer puts the 8500 a909a in the list of USB bootable devices. (Not good!!!)
When the printer is disconnected it isn't a problem. When the printer is connected the computer tries to boot from the printer and the computer hangs.
When I found the printer in the BIOS list of USB bootable devices I DISABLED that item in that list. Then it booted normally.
But now the BIOS takes an extra 30 seconds or so but boot up seems to be preceeding normally.
The guys on the CHAT and PHONE lines didn't even imagine the installer might be a problem so their advice was useless. They were blaming the computer. More importanly, they didn't have a way to escalate the problem. They had no capacity to respond in a flexible manner. It was like dealing with unhelpful staff in the county clerk's office.

HP Officejet Pro 8500 A909g seems to destroy printheads

My wife and I have identical “HP Officejet Pro 8500 A909g Series” (S/N: [Edited for Personal Information] for my printer) printers bought within several months of each other. We have owned the printers since late 2009.
My printer quit printing cyan completely and magenta partially. I replaced both ink cartridges, which did not fix the problem. I then removed the printheads and cleaned the electrical contacts with denatured alcohol and also cleaned the contacts in the printer. This did not fix the problem either.
So I “borrowed” the printheads from my wife’s identical printer and placed it into my printer. That didn’t fix the problem either. When I put the borrowed printheads back into my wife’s printer, it immediately displayed the same symptoms as my printer (it wouldn’t print cyan at all and partially did not print magenta.
The “Self Test Diagnostic Page” of both printers state that the printheads are “Good” in both printers.
During the “Align Printer” task, the LCD on the printer displays a message indicating that the printhead(s) are bad.
Question: is it possible that the printer itself is faulty and causing the printheads to permanently not work correctly?
Second Question: If my printer is bad, what other similar models of all-in-one printers use the same ink cartridges?

Hello Neil-in-Tucson,
Welcome to the HP Forums.
I see that you are having an issue with the Printheads on your printer.
Are you seeing any error codes on the printers display screen?
Please make sure that you have the printer power cable connected directly to a wall outlet and not a power bar/strip. Here is a document that uses a LaserJet printer as an example but it is meant for HP products in general. Please click on the following link that explains the Issues when Connected to an Uninterruptible Power Supply/Power Strip/Surge Protector.
If you like, you can try calling HP's Technical Support to see about further options for you. If you are calling within North America, the number is 1-800-474-6836 and for all other regions, click here: click here. They will be able to get into more detailed troubleshooting.

Hp officejet pro 8500 premier all-in-one printer

The above printer is 1 1/2 years old and it has stopped printing. When the printing became light, I installed new print cartridges less than a week ago. Now, after five days, the printer is consistently cleaning the print heads and aligning the print heads and my documents are not being printed. And, what is most frustrating, during all the cleaning and aligning, all of my new ink is gone and I'm receiving a message replace ink cartridges.
Re: Problem with HP Officejet Pro 8500 printer: cleans printheads every time it's turned on

Well,
to this is say, "get used to it", or throw it away. Many, Many, Many people have had trouble with this printer.
The following are common and frustrating issues that this printer exhibits on a regular basis:
1. Constant Self-Checking (usually every 20-30 pages of print)
2. Very persistant Printhead Cleaning/Checking, (Every startup and after about 20-30 pages printed).
3. Worn-out printheads (usually within 1,100 to 1,500 pages printed).
4. Paper mis-feeds.
5. Paper jams.
6. Nearly impossible to use once the printer reports ink-depletion.
7. Nearly impossible to use CIS Ink for larger print jobs.
8. Ink and printheads "expire" regardless of when they are placed into service. (get a deal on ink or printheads last year? Too bad, the warranty is already expired, most likely).
In short, this printer is the most EXPENSIVE printer I've ever owned, and the most frustrating to use.
I have just over 2,000 pages of regular text printed matter with very little color, and have already gone through 4 sets of ink, and 2 sets of PrintHeads.
Although it's true that you can leave the unit on, and let it go into standby, you should NOT be punished with constant and time-consuming "self-checking" everytime it's turned on, or prints a handful of pages, BUT, it does NOT appear that HP will be standing behind this printer disaster. AND, to make things worse, they've gone on to redesign it, giving it a different look, and so there are about 6 different models/versions of the OfficeJet Pro 8500.
Anyone needing a reliable print/fax/scan/copy solution should look beyond this printer, because it will leave you wanting more, and spending more than you ever imagined you would have to on a late model printer.ro
What is going on? Why does it just automatically clean and align? I also get alignment failed messages. Any suggestiions?

rammerjammer,
Thank you for bringing this to my attention, your feedback is very important and I want to do my best to help. To answer what is going on, since the printing became light, started cleaning itself constantly, and fails the alignment, the printhead was damaged. Click here to see and use the Limited Warranty for HP Ink Cartridges, Printheads, and Related Supplies. There are many ways to contact HP. The number to call is 1-800-474-6836 for HP and Compaq products for Home & Home Office use. If you no longer have a warranty with the printer you can still use the warranty that comes with the printhead or ink cartridges.
If you have a carepack with the printer that extended the one year warranty then the troubleshooting will be covered along with the printer if the printer needs replacing. Check product warranty here, see HP Out of Warranty Support Options for Select HP Consumer Printers here.
To order a new printhead you can go to HP Sure Supply and enter your printer or go to the HP Parts Store and order the printhead by part number C4900A for the Black and yellow and part number C4901A for the Cyan Magenta. These printheads go by region also so be sure you are using the right region, these were found using the United States region.
The HP Officejet Pro 8500 Premier All-in-One printer has separated the ink cartridges from the printheads. The ink cartridges are on the lower left and the removable print heads are on the carriage inside the printer. The printer goes through a calibration process when turned on that will use ink. Leave the printer on and let it go into stand by mode. This type of printer is energy star efficient and made to calibrate on start up and be left on. Allow the printer to clean or calibrate only if the printer must. If it starts cleaning a lot it may be time to do a little maintenance to the printer (recommend once a month for maintenance). Please see the following links for further details.

Officejet Pro 8500 User Guide
The printer has a duty cycle of 7.5k page/month. The XL cartridges have a composite page yield of 1.4k pages with about a third of the black ink left over. To me it would seem that the printhead should last somewhere in between. This printer was designed to save money on ink compared to the rest of the officejets. I hate that it has been causing so much trouble, hopefully the information I provided will help.

Officejet Pro 8500 Premier - only one printhead is displayed in 'Printheads Health' window

I changed the black/yellow printhead today in my HP Officejet Pro 8500 Premier printer. When I closed the lid, the printer did its housekeeping thing, clicking away while it aligned heads, etc, and printed out a diagnostic sheet that looked terrific.
So I wanted to see what the HP Utility would report as the health of both printheads now. Only the Cyan/Magenta printhead health was displayed, both before I changed the printhead and now after I changed the printhead. The utility reported the Cyan/Magenta printhead was in GOOD condition, along with a green button.
But there was no image of the Black/Yellow printhead at all, so no button showing the health of the printhead that I just installed.
While I was installing the new printhead, I wiped off the gold contacts on the printer where the printhead's contacts would meet. They were clean.
Any suggestions aboutwy the software does not display the health of BOTH printheads?
My operating system is Mac OS X 10.6.8

Hello garden-2009,
Welcome to the HP Forums!
I understand only one printhead is displaying the health using the Officejet 8500. I will do my best to assist you! I would recommend contacting HP technical support for further assistance. Click here to find out: HP Worldwide Contact.

I have my HP OfficeJet Pro 8500 A connected to my Mac Book Pro on a Wireless network. It works and

I have my Hp Officejet Pro 8500 A connected to my MAc Book Pro which is running Lion OS on a wireless network. It works just fine and prints and everything. The problem is a "HP Utility" window that pops up on my screen and says it is "connecting to device" and lists my printer. It just runs and runs and the entire thing is gray - meaning I can't close it, cancel it, or anything. When you try to click on it, the arrow becomes the color wheel of death. It is driving me crazy. I have gone through settings, I have downloaded the latest drivers, I have looked in utilities, I have opened the printer folder and can't find where this thing is coming from or how to turn it off. Please help. And yes I have turned offf the computer and rebooted.

If you are using Snow Leopard or Lion and have HP software for pre-Snow Leopard (either from a CD not marked as compatible with 10.6 or you recently upgraded to Snow Leopard or Lion and had the HP software on your Mac before you upgraded - even if you did a standard uninstall of the old software or installed new software over the top of it) you must uninstall the software using the 'scrubber' option:
Go to Applications/Hewlett Packard/ click on HP Uninstaller
Click on Continue
Highlight your device on the left pane
Press and hold Control + Alt + Cmd keys on the keyboard simultaneously while you click on Uninstall <<<< This IS the Scrubber Option, there is no button labeled "Scrubber"
There will be a pop up that asks if you are sure you want to uninstall ALL hp software. (At this point, if you continue, any HP printers you have installed will need to be reinstalled)
Click Continue and let it finish
Restart your Mac
Download and install this: http://support.apple.com/kb/DL907
Now reset the printing system:
- Sys Prefs, Print & Fax
- Right (control) click in the rectangle listing your printers and select Reset Printing System.
WARNING - this will delete ALL of your printers!
- Select the plus sign to re-add it. Look for the printer, select it and wait until the "Add" button becomes available. Click it.
If you want more features, you can download and install the Full Featured software from the "Support & Drivers" button at the top of this page, otherwise, basic printing and scanning will work without it.

Print Quality Issues on OfficeJet Pro 8500 A909g

The print utility says that the onlly cartridge getting low on ink is the yellow, but the guide says not to change the cartridge until it gives you the message to change it. And it has been printing OK until today, when the black ink started getting splotchy. But the utility shows plenty of black ink in the cartridge. I cleaned the print heads, and that changed nothing. I printed out a print head health quality test, and oddly the only thing that printed was two blocks of magenta--the rest totally blank. Odd because the print utility only shows the yellow getting low and that not even ready to change.
I don't want to open up new cartridges for nothing because these signs don't necessarily add up to this being due to empty cartridges. So I am stuck as to how discover what the problem is.

Hi @Hazelg

My HP Officejet Pro 8500 A910 will no longer print aqua.

My HP Officejet Pro 8500 A910 will no longer print aqua. I just tried two new cartridges and when I clean the heads, no aqua prints. I get no error messages however.
One possible issue: Recently I used a new HP aqua print cartridge (940XL version) that kept stalling my printer. If my printer sat without printing for 10 minutes or more, the only way I could get it to print would be to shut down the printer and restart it. Then, as long as I kept printing, it worked fine. When I replaced the problematic print cartridge the printer works fine except now it won't print aqua. Could the problematic cartridge damaged something?
I looked at the print head and it looks fine. What is strange is that NO AQUA INK at all shows on the print head page.
What should I do? Help!

Hey @CWickstrom ,
Thank you for taking the time to post on the HP Forums today! Hope you enjoy the experience.
I recommend calling HP Technical Phone Support for this issue I believe you will be given options and help I can't.
If you are in Canada or US call 800 474 6836, or you can Contact HP Worldwide.
HP printers generally have a 1 year warranty from their purchase date, you can verify the warranty using the following link if you would like; warranty check.
I hope this helps.
