Below are the instructions I got off the HP site on how to try and fix the printer:
Dust, paper fiber, and other debris might accumulate on the paper feed rollers and cause paper jams and paper feed issues. Clean the rollers inside the printer, and then try to print again.
Gather the following materials:
A lint-free cloth
Distilled, filtered, or bottled water (tap water might damage the printer)
- Turn off the printer, and then disconnect the power cord.
- Disconnect the USB cable, if it is not already disconnected.
- Raise the input tray.
- Lift and hold the input tray shield.
- Look down through the open input tray and find the gray paper pick rollers. You might need a flashlight to illuminate the area.
- Dampen a long cotton swab with bottled or distilled water, and then squeeze any excess water from the cloth.
- Press the swab against the rollers, and then rotate them upward with your fingers. Apply a moderate amount of pressure to remove dust or dirt buildup.
- Lower the input tray shield.
- Allow the rollers to dry for 10 or 15 minutes.
- Reconnect the power cord to the rear of the printer, and then turn on the printer.
- Reconnect the USB cable to the printer if necessary.
I have a suggestion how about making it easier to access the printer rollers. Then you might be able to actually fix the damn thing.
