HP OFFICEJET PRO 8600 CONTROL PANEL IS VERY DIM

I have the hp officejet pro 8600 printer. The control panel is very dim I can barely read the panel. I have tried the trouble shooting suggestions and adjusting the brightness on the panel. None of this works. Any sugguestions? Thanks for your help.

Hello,
This seems like a hardware issue, I would suggest doing a hard reset with the printer, and making sure the printer is plugged into a wall outlet and not a surge protector.
If the step below doesn't work, please try and call HP @8004746836 and see what options they have to assist you.
Hard Reset:
Take out the toner/cartridges
Unplug the power cord from the printer and wall
Wait 30 sec
Plug the power cord back into the printer and wall (Make sure the printer is plugged into the wall and not a surge protector)
Insert the toner/cartridges back into the printer
Let me know the outcome

HP Officejet Pro 8600 control panel is just a blank screen

My warranty has expired - and my touchscreen just went blank! I have tried all the troubleshooting ideas others have (unplugging from the machine, unplugging from the wall, etc.). Nothing has worked thus far.
My question is - this appears to be an issue that many of us are having. Is HP doing something about this? Or do we just buy new printers every 16 months? I love(d) this printer - and I have found some work-arounds by using the icons on my computer. But it is not convenient and does not work for everything.
Please let me know if anyone has found a way to fix this - and if HP is going to do something about this very coincidental issue that we are having.
Thanks!

Hello otcheryl,
Welcome to the HP Support Forums!
Sorry to hear about the display screen issues you have been experiencing with the Officejet Pro 8600. I seen that you have also posted here: Re: PRINTER DISPLAY SCREEN ALMOST COMPLETELY WHITE (TOO BRIGHT/FADED/?). The troubleshooting provided by Advance23 covers all of the support options available with a service.
On the off chance you have not looked within the last couple days, I see that there has been a firmware update for this printer released just this past Friday.
If you have a Windows computer, a USB and a small amount of time, it will be worth a try.

Hp Officejet Pro 8600 Premium suddenly printed very slowly from PC

Hi, and thanks for any insights.
I have a client with an Officejet Pro 8600 Premium, and printing to this printer over USB has suddenly become very slow. The dedicated PC is XP with 2 GB of ram and only using 40 GB on a 200 GB drive. The printer has two trays, with tray1 dedicated to checks, and tray 2 for anything directed to plain paper. The printer is not connected to a network, but dedicatd to this PC. The PC is current with updates.
Checks print at the normal speed, and copying prints at reasonable speed, but whejn printed from the PC anything directed to tray 2 prints at a snail's pace . This is new behavior.
I have printed status pages and performed print head and allignment processes. Still, this behavior persists.
I looked i the event log and saw nothing that suggested an evident system issue. Windows update only shows Security Essentials updates for the duration during which the slowness started.
The PC is not acting strangly in any other way.
Any suggestion would be helpful.

Hi,
The information is very general, this applies for many HP printers:
Solution 1: Use a lower print quality setting
Solution: Check the print quality setting. Best and Maximum dpi provide the best quality but are slower than Normal or Draft. Draft provides the fastest print speed.
Cause: The print quality was set to a high setting. If this did not solve the issue, try the next solution.
Solution 2: Check the ink levels
Solution: Check the estimated ink levels in the ink cartridges. NOTE: Ink level alerts and indicators provide estimates for planning purposes only. When you receive a low on ink message, consider having a replacement cartridge available to avoid possible printing delays. You do not need to replace the ink cartridges until print quality becomes unacceptable.
CAUTION: Wait until you have a new ink cartridge available before removing the old ink cartridge. Do not leave the ink cartridge outside of the printer for an extended period of time. This can result in damage to both the printer and the ink cartridge.
For more information, see: Check the estimated ink levels
Cause: The ink cartridges might have insufficient ink. Printing with depleted cartridges slows the printer. If this did not solve the issue, try the next solution.
Solution 3: Contact HP support
Solution: Contact HP support for service. Go to: www.hp.com/go/customercare. This website provides information and utilities that can help you correct many common printer problems.
If prompted, choose your country/region, and then click Contact HP for information on calling for technical support.
Cause: There was a problem with the printer.
Regards.

Control display panel Officejet Pro 8600

The all-in-one is about a year old. It's been working fine, but suddenly the control panel display went blank. The phone keys are gone, no icons show up... the only things I see are the little house, the ? and the two arrows surrounding a white screen where the icons used to be. I've tried unistalling & reinstalling, but that made no difference. Any ideas?

Hello @Mimzy-2015 , and welcome to the HP Forums, I hope you enjoy your experience!
I see you're having problems with the printer control panel. I would like to try and help.
I'd recommend starting with a power reset on the printer. Disconnect the power cord from the printer and the power outlet, then wait 60 seconds. After 60 seconds, plug the printer back in. Ensure you plug the printer directly to a wall outlet. Make sure to bypass any sort of surge protector or power bar.
Another suggestion would be to plug the printer power into a different wall outlet.
I would also recommend updating the printer firmware:

Good luck and please let me know the results of your troubleshooting steps. Thank you for posting on the HP Forums!

Hi Liam,
The installation CD that came with your 8600 will definitely not work with Windows 8.1 and is not same as the latest online download which you will need to install on Win8.1.
Are you running Win8.1 Pro 32 or 64 bit?
Also make sure you select the right model of your Officejet. There are 3 different models.

Try uninstalling printer from the control panel and reinstall using the Win8.1 download from the link above.

Officejet Pro 8600 Plus software

I have the ability to print from the computer so I know the HP printer drivers are functioning. I have also verified that I can initiate a scan from the printer and from the computer using the "HP Scan" icon via the Start menu.
The problem is that I cannot run the HP printer software suite via the shortcut icon on the desktop or via the file icon in the source folder.
The printer is connected via an Ethernet cable to the house network. I have deleted and reinstalled the software suite and when it gets to the point of finding the printer, it fails. When I plugged in the product name it couldn't find it so I used the network address (192.168.1.4 - taken off the Windows Printer Test Page) and it continues the install until it seems to finish. It places the "HP Officejet Pro 8600" icon on my desktop along with its "Shop for Supplies - HP Officejet Pro" icon. If I click on the "Shop for Supplies - HP Officejet Pro" icon, it takes me to the appropriate Shop For Supplies Online entry screen. When I double click on the "HP Officejet Pro 8600" icon, it very briefly gives me the Windows little "working" swirl but does not open the software application.
I tried uninstalled the printer using Windows "Devices and Printers" Control panel, then deleted the HP software using "Programs and Features", then reinstalling everything using new drivers and HP software via their web site. This has not changed any of the symptoms or results.
This question was solved.

Hi GL1800A,
Hope all is well!
One last thing you could try, if you want to, is to go through this guide, HP Single-Function and Multifunction Printers - HP Printer Assistant Opens with a Script Error or in..., and try the patch that is included.

Can't Open Officejet Pro 8600 Software in Windows 8.1

I have Windows 8.1 64 bit. I installed Officejet Pro 8600 e-all-in-one-printer N-911a using OJ8600-1315.exe. The printer and software worked fine in Windows 7. In Windows 8.1, the printer works well wirlessly. It prints, scans, and copies with no problem. I can use the window on the printer to start scanning and copying. However, I have an icon on the Windows 8.1 Start Page that says Officejet Pro 8600. When I click on it, it opens a window labled HPSolutionsPortal.hta - Microsoft Visual Studio. I do not get the Officejet software where I can control the resolution of scans and files produced by the printer. How can I access the HP Officejet Pro software?
This question was solved.

Gi,
From the Control Panel go to Programs and then select Default Programs.
Click on Associate a file type or protocol with a specific product.
Locate the .hta prefix, double click it, click on More Options and select the Microsoft (R) HTML Application host option instead the selected Visual Studio.
If you cannot find this option within the list scrool to its very end and click on Look for another file on your PC.
Browse and select C:\windows\system32\mshta.exe.

Poor image quality when scanning coins with officejet pro 8600 plus

I recently upgraded my printer from an HP 2210 to and HP officejet pro 8600 plus. image quality on coin scans is terrible.
I have tried scanning both with the HP software and with windows 7 fax and scan software
I have saved images as BMP, JPG, PNG, and TIFF
I have used resolutions from 300 dpi to 1200 DPI
All give me similar unacceptable results.
Images are better when scanned flat on the scanner than when in slabbed holders, and from this I am guessing that the plastic is somehow interfering wiht the scan. Either that, or there is a very shallow depth of field so that even moving the coin a few mm away from the glass moves it out of focus. But even a raw coin placed directly on the glass has significantly worse image quality than the old 2100.
The first image is a coin scanned with the old 2100. The second has been scanned in a similar slab by the 8600

Hi terry_renee,
Welcome to the HP Forums! I am happy to help you with this scanning issue! I did a test with an HP Officejet 8600, at 1200 dpi, and no plastic covering. Just the quarter on the glass, and we cropped it to the quarter. This is the result.
I have a few questions for you:
What Operating System are you using for scanning? Windows or Mac? What version?
What scanning software are you using?
Are you scanning from the computer, or the printer's control panel?
Hope to hear back from you, and have a great day!

HP Officejet Pro 8600 N911a - Print when Fax is Not Saved

Can I make it so a fax is printed when it's not saved? I know I can set it to print and save every time, but I rely on HP Digital Fax to save paper. If a fax is not saved, either due to a network error or if the computer that it usually saves to is shut off, can the fax just be printed?

, it's nice to meet you. I think I found something that may help with your faxing dilemma. This information was in the User Guide for the Officejet Pro 8600 e-All-in-One Printer - N911a; pg 69. Set up backup fax Depending on your preference and security requirements, you can set up the printer to store all the faxes it receives, only the faxes it receives while the printer is in an error condition, or none of the faxes it receives. The following backup fax modes are available:On > The default setting. When Backup fax is On, the printer stores all received faxes in memory. This enables you to reprint up to eight of the most recently printed faxes if they are still saved in memory. NOTE: When printer memory is low, it overwrites the oldest, printed faxes as it receives new faxes. If the memory becomes full of unprinted faxes, the printer stops answering incoming fax calls. NOTE: If you receive a fax that is too large, such as a very detailed color photo, it might not be stored in memory due to memory limitations.
On Error Only > Causes the printer to store faxes in memory only if an error condition exists that prevents the printer from printing the faxes (for example, if the printer runs out of paper). The printer continues to store incoming faxes as long as there is memory available. (If the memory becomes full, the printer stops answering incoming fax calls.) When the error condition is resolved, the faxes stored in memory print automatically, and then they are deleted from memory.
Off > Faxes are never stored in memory. For example, you might want to turn off Backup fax for security purposes. If an error condition occurs that prevents the printer from printing (for example, the printer runs out of paper), the printer stops answering incoming fax calls. NOTE: If backup fax is enabled and you turn the printer off, all faxes stored in memory are deleted, including any unprinted faxes that you might have received while the printer was in an error condition. You must contact the senders to ask them to resend any unprinted faxes. For a list of the faxes you have received, print the Fax Log. The Fax Log is not deleted when the printer is turned off. To set backup fax from the printer control panel 1. Touch (right arrow), and then select Setup.2. Touch Fax Setup, and then select Advanced Fax Setup.3. Touch Backup Fax Reception.4. Touch On, On Error Only, or Off. Reprint received faxes from memoryIf you set the Backup fax mode to On, the received faxes are stored in memory, whether the printer has an error condition or not. NOTE: After the memory becomes full, the oldest, printed faxes are overwritten as new faxes are received. If all the stored faxes are unprinted, the printer does not receive any fax calls until you print or delete the faxes from memory. You might also want to delete the faxes in memory for security or privacy purposes. Depending on the sizes of the faxes in memory, you can reprint up to eight of the most recently printed faxes, if they are still in memory. For example, you might need to reprint your faxes if you lost the copy of your last printout. To reprint faxes in memory from the printer control panel 1. Make sure you have paper loaded in the main tray.2. Touch (right arrow), and then select Setup.3. Touch Tools or Fax Tools, and then select Reprint Faxes in Memory. The faxes are printed in the reverse order from which they were received with the most recently received fax printed first, and so on.4. If you want to stop reprinting the faxes in memory, touch the Cancel button. Please let me know if these steps resolved your issue, or if there is anything else I can do to help. I look forward to hearing from you! Thanks,

Officejet Pro 8600 Plus won't print or scan wirelessly using Mac OS 10.

Mac OS 10.9
Wireless
My printer was working fine until today. Then when I used the control panel to scan a page I went through the steps and got to scanning and got the message I needed to enable "Scan to Computer" in the HP Utility. I went there and it was unchecked. Seems I had this problem every time I did a new scan job in the past. It wouldn't retain than check. So I checked it and after awhile I got the message "Communication Error" and to check my connections and if that didn't work restart my computer and printer. I did that and also restarted the router but it didn't help.
Then I tried printing from Word, which has always worked but it didn't this time. The printer icon on the right of the dock came up, bounced a few times then disappeared with nothing happening on the printer.
So I deleted and reinstalled the printer. No help. I downloaded and installed HP software and firmware updates. No help. I went through wireless setup. No help
BTW, all along I got good "Wireless Network Test" results. I says it's connected but nothing happens when I try any functions of the printer.
If I can find a USB cable I will try to see if wired works.
Any suggestions would be appreciated.

Hey @neoflyer,
I would like to assist you today with resolving the wireless printing and scanning issues you're experiencing on your HP Officejet Pro 8600 Plus e-All-in-One Printer on your Mac OS X 10.9 Operating System. You mentioned that you have powercycled the devices, reran the wireless setup, and uninstalled and reinstalled the software and drivers to no avail. I'm going to suggest a few additional troubleshooting steps to verify if this is a computer issue or a network issue.
Step 1: Gather the IP and Open the EWS:
1. On the screen of your printer select the wireless button:
2. Under the Wireless information you should see your IP address
3. Open up your internet browser on your Mac computer and in the website address bar just type in your IP address. Please do not include www.
4. After you enter your IP address in the website bar go to that website
5. If the website for your printer opens than that proves with 100% certainty that your printer and computer are 'talking' to each other on your wireless network. If the website fails to open than you have a network communication issue with your router.
If the website fails to open please powercycle your network again:
How to Properly Powercycle a Network:
First, unplug the power cable to your Router
Once your Router is unplugged, turn off your printer
Next, shut down your computer
After 30 seconds to 1 minutes, plug your Router back in
Next, turn on your printer
Turn on the computer
After a few moments check on your computer and ensure that the internet is working. Once it is, hit the wireless button again on the printer to see if your printer got a new IP address. Using the IP address enter it in the address bar of your internet browser and now see if the website for the printer opens.
If the website for the printer opens successfully please follow the steps below:
Step 1: Uninstall Drivers and Software:
From the computer desktop, double-click the Macintosh HD, and then click Applications.
Click the Hewlett-Packard folder.
Double-click the HP Uninstaller, and then click Continue.
Select the product to uninstall, and then click Uninstall.
When prompted, type the Administrator name and Password, and then click OK.
From the Macintosh HD menu, click Users.
Click the correct user name.
Click Library.
Click Preferences.
Click and hold the cursor on the first file that starts with "HP," and then drag the file to the Trash icon on the taskbar. Complete this step for each file that starts with "HP."
Close out of Preferences.
Click the Trash icon on the taskbar, click the Empty button, and then click OK to empty the trash.
Step 2: Verify and Repair your Disk Permissions on the Mac:
Open Macintosh HD and go to Applications
Go to the Utilities Folder
Open the Disk Utility
Select the Hard Drive volume you are using (usually on the left)
Select Verify Disk Permissions
Once that process is done, select Repair Disk Permissions
Step 3: Check for Apple Updates:
Go to Apple
Select System Preferences
Select Software Update
Click Update Now
Install your available updates
Restart your computer
Step 4: Reinstall your Software and Drivers:
1. Please click the following link to download the appropriate Mac OS X 10.9 drivers for your printer: Mac: HP Officejet Pro 8600 series Full Feature Software and Drivers
2. Once downloaded, run through the step by step screens to reinstall your network printer
3. Once the printer is reinstalled, attempt a print and a scan!
Please let me know if these steps resolved your issue. Thanks for reaching out to the HP Support Forums. Good luck!

OfficeJet Pro 8600 N911g cannot complete s/w installation on laptop running XP

Initially, successfully installed the 8600 s/w on a Dell D810 laptop running XP which is linked both via Ethernet and wirelessly to the same LAN as the printer. The printer is wirelessly linked to a port on a WAP device connected to the LAN/router. After setting up the router with DNS 8.8.8.8 and 8.8.4.4 addresses, successfully set-up e-Print function thru Verizon high speed internet connection. This confirms that the my LAN and Internet can see the printer connection through the WAP. Guess I should have left well enough alone, but I decided to also install the printer on my desktop, a Dell XPS desktop (also running on XP) that is linked thru a wired Ethernet connection to the same LAN.
The XPS s/w install was flawless and I can print from the desktop and HP e-print functions continue to work on the 8600, but I can no longer print from the laptop. As I mentioned, the s/w did load successfully on the laptop when I initially installed the printer. Following a suggestion on HP's website, I uninstalled the HP 3800 s/w in an attempt to reinstall the printer on the laptop. However, I have not been able to successfully reload the s/w on the laptop, despite numerous attempts.. The program can find the printer on the LAN, it always comes up with the same result: "The printer was unable to be installed over the network". I confirmed that there is no firewall or security setting blocking the s/w load.
As part of my problem resolution, I've also followed the procedures contained in HP Troubleshooting Your Wireless Connection but still cannot complete the installation process on the laptop. In my latest attempt to resolve the problem, I marked the 8600 as shared on the XPS desktop system, as suggested in another post, but suspect that would only affect USB-connected printers, not those that are wirelessly connected.
When I downloaded the HP Hardware Diagnostic Utility (HPHDU), it also was able to find the printer on the LAN but displayed a message: "We're sorry but the OfficeJet Pro 8600 N911g in not supported by this utility".
Can anyone offer a suggestion as to why the 8600 install worked successfully when initially loaded on my laptop but I cannot reload it? That could provide a clue as to what is blocking the reinstallation on the laptop. As I said, the desktop s/w loaded successfully and I can access the 8600's functions from there. Each of the HP utilities I downloaded from HP and have run on the laptop can find the 8600, but none can complete the s/w load so that I can use the printer from the laptop.
The LAN also has an Ethernet link to a HP OfficeJet 7310 that can be accessed from any PC on my network, so I reluctant to entirely remove all HP software so I can at least have one printer operational. I feel like I am on the bleeding edge of technology so any help is appreciated!
Thanks.

I can print a test page from my Mac to my HP Officejet Pro 8600 but nothing else will print

Hi - I just recently had a hard drive crash and had to revert to an old Time Machine backup on my new hard drive to get my Mac back. Since getting back up and running I have been unable to get my Officejet Pro 8600 back online. My computer is wired to the wireless router but the printer is running wireless. My computer can see the printer just fine and I can even print a "Print Quality Diagnostic" report from my Mac to the printer from the HP utility. But nothing else will print. The firmware is up to date. I have tried resetting the printing system multiple times, rebooting the machine, etc... Nothing works. Any help would be appreciated.
If it helps, we were using a different printer the last time the time machine was backed up, so when we used that backup the old printer was showing, but I reset the printing system, so it shouldn't matter.
Thanks for your help!

Hello @Ryan221,
Welcome to the HP Support Forums! I see your hard drive recently crashed and now you are not longer able to print to your HP Officejet Pro 8600. I see you have reset the printing system with no success. Let's try a different approach:
Scrub/ Uninstall
• Open the Applications folder > HP or Hewlett Packard folder > HP Uninstaller
• Click continue, click on one of the printers in the list.
• * Only do this step if you do not have any other HP Printers. Hold down Control, Option and Command, While holding the three buttons down,
• Click uninstall.
Reset Printing System
1. Click the Apple icon ( ), and then click System Preferences.
2. In the Hardware section, click Print & Fax/Scan. The Print & Fax/Scan dialog box opens.
3. Right-click (or Ctrl +click) in the left panel, and then click Reset printing system…
4. Click OK to confirm the reset.
5. Type the correct Name and Password.
6. Click OK to reset the printing system. The Print & Fax dialog box shows no printer selected
Note: This will remove all printers in the print and Fax/Scan, any printer removed can be re-added later by clicking the plus (+) symbol..
Repair Disk Permissions
1.On the Dock, click Applications, and then click Utilities.
2.Double-click Disk Utility.
3.Highlight your hard drive/partition on the left (by default this is "Macintosh HD").
4.Click the Repair Disk Permissions button at the bottom of the window.
5.Once the repair is complete, restart the computer.
Restart the printer. Now you can download and install the printer software and install it. Click on the link below to begin the download and follow the on screen instructions:
HP Officejet Pro Full Feature Software and Driver - Mac OS X 10.6, OS X 10.7, OS X 10.8
I hope this helps, please let me know the outcome!
