HP Officejet Pro 8500 Leaves a black horizontal line while copying

HP Officejet Pro 8500 Leaves a black horizontal line while copying . It can print fine, but whenever we make copies (black, or color) we get a straight horizontal line running across the page. I'ts a perfect line, no streaks, nothing i do can fix it, any ideas?

Are you putting the copies through the auto feeder? If so, you might want to clean the roller and the glass that it would roller over. I also clean the white bar that is on the bottom of the cover.
I have the same issue but it is white line when I am scanning.

HP OfficeJet Pro 8500 A910 - Unable to get it to copy, receive a fax, scan, or print

Dell Studio
Microsoft Vista .. 64
HP OfficeJet Pro 8500 A910
Up until a week ago, this printer was performing just fine. I am unable to get it to copy, receive a fax, scan, or print.
==============================
Unable to print.
Job in queue. printer screen says "now printing", However, nothing prints.
When I tried to reinstall the drivers, I got ... "Error 0X00000643"
Ran "EndError" scan and fixed any/all problems.
Still ... No Joy. Still .... Unable to print.
Tried printing a "Test Page".
Still No Joy !!
Screen on printer says "Now Printing"
However, nothing happens.
Does anyone have a suggestions?
Thanks In Advance,
EarlLJ

Same problem here. Already got it replaced with a refurb machine three times. Was fine for a while, then it started the same problem again. Any idea, before I toss it out of the window?

Officejet Pro 8500 Premier: How do I force the Copy function to use paper from Tray 2?

I set the default tray to Tray 2 and locked Tray 1 to protect my envelopes and this works fine when printing from the computer. But when I copy a document using the START COPY button, the printer pulls from Tray 1 and complains about the media being the wrong size.
When I use the printers control panel to set the Copy function to use Tray 2, it resets itself to Tray 1 the next time I copy something.
Surely I am not the only one in the Universe who would want to configure my printer to do this.
Has anyone else out there tried this?
Also, is there a specific forum for the Officejet Pro 8500 series printers?

Hi
Hope you're still checking this
I had the same problem but found that if you go to the copy menu through the touchscreen, change the tray to tray 2 and then scroll to the very bottom there is an option to "Set as new default". This also changes the default for the Start Copy buttons - at least it did for me anyway.
Good luck

Officejet Pro 8500 A910 has poor black ink quality

My Officejet Pro 8500 A910 prints black with very poor print quality (faint printouts with white lines through them). This began happening after I installed a new HP 940XL cartridge and updated the printer software last week. (I had previous issues with not being able to scan directly to my Mac, which lead me to update my printer software.)
My computer is a MacBook with OS X 10.6.8 (Snow Leopard). I print over my home wifi network.
I cleaned my printheads (one cleaning cycle), but that has not helped. Do I need to run more cleaning cycles? Should I replace my printhead? Are new printheads available from OfficeMax or other office supply stores which sell HP ink?
Thanks for your assistance.
Joanne

Please try the steps in this document: c01980797
You can try one more Print head cleaning cycle.
Hope this helps.

Have a great day!!!

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.

Hp Officejet Pro 8500 will print but not anything with black ink. It keeps aligning itself.

My Hp Officejet Pro 8500 will print but not anything with black ink - i have checked the black ink cartridge and it is full. Whenever i print anything in colour (only option) the printer goes into an alignment/maintenace loop that lasts for a long time and does not fix the problem. What should I do?

Clean your printerhesd 4-5 times until the black fully restores. I am on my third complete cleaning and have gone from 0% black to approx. 60-70%. So, it works just takes time.

HP OfficeJet Pro 8500 Premier doesn't print black, only color

The OfficeJet Pro 8500 was printing normally, then it began cycling repeatedly through cleaning the printhead so I turned it off and back on. I also replaced the black ink cartridge. Now it prints as requested with normal functionality in my hoome network, but it only prints the color features of a page, not black.
Please help.

Hello LindaSN,
Welcome to the HP Forums.
I see that you are having an issue with printing black ink.
I do have a few suggestions we can try in that attempt to troubleshoot this issue.
First off, 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.
I have also done some research and I have found a great document that deals with Fixing Print Quality Problems for the HP Officejet Pro 8500 All-in-One Printer Series (A909).
Please feel free to write me back if you have any other questions or concerns.
Cheers,

NEW printer Officejet Pro 8500 A910 [9EDF91],NOT PRINTING in black !

NEW printer Officejet Pro 8500 A910 [9EDF91], initial prints had streaks, so I did print head clean, switch off, start again, and now it does NOT PRINT in black at all. I have tried everything. VERY FRUSTRATED, can't get in touch with HP assist. Any ideas what could be wrong?

I am having the same problem. I was able to print one thing in black (the fax report during printer setup) and now I can't print in black at all!
About to return the product if I can't figure out a solution....

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.

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.

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.

HP Officejet Pro 8500 A909g - Streak down middle of the page during scanning only

When scanning documents there is a black streak down the middle of the page. I have already followed the help instruction to clean the glass, rollers, etc... I have turned off the computer and the copier & then restarted. I'm still having the same problem???

Welcome to the HP Forums Bjoyful,
I read your post, which indicates that you are getting a black streak down the middle of the page when scanning.
I can help you with this.
I would do a hard reset to see if that will resolve the issue.
Leave the printer on and unplug the power cable from the printer and wall outlet for 60 seconds.
Then reconnect the power cable to the printer and wall outlet rather than a surge protector.
This ensures the printer is receiving full power and may help this situation. When scanning with a surge protector, it can cause the vertical lines.
Just to make sure this is the document you followed to clean the glass and rollers, I have included it.
Vertical Bands, Streaks, or Lines in a Copy, Fax, or Scan.
Update the printer's firmware if you are still having issues. HP Officejet Pro 8500 Wireless All-in-One Printer - A909g Drivers.
Do you get the black lines scanning from the glass and the ADF?
If you need further assistance, let me know.
Have a wonderful day!
Thank You.

Officejet Pro 8500 - first page (or two) of the day is smeared.

The first page or two that I print, after the machine hasn't been used for an hour or more, will come out smeared at the top and with insufficinet ink in the top area of the page. I've cleaned the print heads lots of times - that does not solve the problem. Is there a solution for this problem? Thanks!!
