If you have printhead issues, follow these steps:
-
On a Windows XP, 7, 8, or 10 PC with a USB connection to the printer, download a zip file with your firmware.
- Open the zip file and run the HP DesignJet 500/800 Firmware Upgrade Tool A.05.01.
- Wait for the upgrade to complete, and then turn the printer off, and then back on.
-
If the steps above do not help please contact HP for a replacement , rather than returning to the retailer.
