Repeat paper jam messages but the printer keeps spewing out blank paper on my HP OfficePro 6978 (Mac OS).
When I try to print, the paper stops under the paper tray. Rollers seem free to move. The paper tray seems to be seated correctly (it clicks into place on both sides).
I've reset the printer (unplugged while turned on, hold down start button 30 seconds, plug back in). I've cleaned the rollers and made sure the ink cartridge can move freely. There are no firmware updates for my device.
This seemed to start simultaneously with getting this message: "Previously used genuine HP cartridges installed." I replaced with a new cartridge but keep getting the same message over and over. I've cleaned the sensor in the printer and on the cartridge. Now I'm getting the message that all three color cartridges I installed two days ago are low on ink.
Please reach out to the HP Support in your region regarding the service options for your printer.
If you are having trouble navigating through the above options, it's most likely because the device is out of warranty. If yes? please send me a private message with the region from you are contacting us from. Check next to your profile name, you should see a little blue envelope, please click on it.
