Hi @LBSW15,
Thanks for engaging in HP support Forums! This is a wonderful location to converse with the community, get assistance and find tips! I came across your post and wanted to assist you. I understand you are getting '0x' error message on your HP DeskJet Printer. Don't worry as I have a few suggestions which should help you resolve this issue.
To provide you with an accurate solution, I'll need a few more details:
Did you make any changes on the printer before the issue started?
Are you using genuine HP ink cartridge or refilled ink cartridges?
Have you tried to clean the ink cartridges or rollers?
Are you able to move the carriage freely?
In the meantime, let's start off by performing 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.
Remove all the ink cartridges and then try to perform a hard reset on the printer.
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.
Now insert the ink cartridges and then try to print a test page and check if it works.
Next thing, I would suggest here is to follow the steps suggested in the support document for - HP Printers - Resolving Printhead Problems and Ink System Failure
If you have followed the steps suggested and still having the issue, I would personally suggest this could be a printer hardware. I would recommend you contact our HP phone support for available service related options. If your product is out of warranty, please don't forget to choose the paid options to get the tech support number.
