OfficejetPro 8500a Touch Screen

[ChaplainJohn]

Like others, the right side of the touch screen stopped working.  I have tried troubleshooting with all the steps and no success.  Given HP is registering this on the forum as a frequent problem -- Does HP stand behind their product with a solution?  The printer works fine -- but without the screen, I can't seem to get wireless printing to work anymore.

@ChaplainJohn,

Thank you for showing your interest in HP Support Forums. It is a great place to find the help you need, from other users, HP experts, and other support personnel. I see from your post you are in need of support and I'll be glad to help you out.

As I see you are having issues with the touchscreen on your HP OfficeJet printer is partially working.

I would suggest here is to try these steps here to understand if this is a hardware or software related issue.

Let's start off by updating the printer firmware. If your printer connected wirelessly, make sure to temporary connect the device with USB and then follow the link to install the latest firmware update on your printer from our HP support website. Once done, restart the printer. For more details on how to update, please use this link: HP Printers - Updating or Upgrading Printer Firmware

If the issue persists, I would suggest here is to do a hard reset on the printer and make sure that the printer is connected directly to the wall outlet and not to the surge protector.

With the printer turned on, disconnect the power cord from the rear of the printer and also unplug the power cord from the wall outlet.

Remove USB cable, if present.

Wait for 2-3 minutes, press and hold the power button on your printer for about 30 seconds to remove any additional charge.

Now plug back the power cable straight to a wall outlet without any surge protector or an extension cord and then plug back the power cord to the printer.

Turn on the printer and wait till warm-up period finishes and the printer is idle.

If the issue persists, I would suggest you go through these links here: 

Link 1: HP Printers - The Printer Display Is Blank or Black

Link 2: HP Officejet Pro 8500 Printers - The Touchscreen Does Not Respond(Though the header is different but the steps mentioned should work for your printer as well).

Hope this answers your question.

Good luck and keep me posted about the developments. If this helps, please mark this as “Accepted Solution” as it will help several others with the same issue and give the post a Kudos for my efforts to help. Thank you and have a great week ahead. 🙂
