2) Reset the printer

• Press the power button to turn off the printer. If it does not turn off, disconnect the power cord from the printer.

3) Check for paper jam or false jam conditions

Notes that some jam errors can be real or false.

• Inspect the input tray
• Inspect the output tray
• Inspect the printhead access area
• Inspect the bottom of the printer for jammed paper or foreign objects

Obstructions in the paper path can trigger printer errors.

4) Clean the paper path rollers

HP provides two roller-cleaning approaches:

• Automated cleaning tool from the printer control panel
• Manual cleaning of the paper-pick rollers using a lint-free swab and distilled/bottled/filtered water

5) Make sure paper is loaded correctly

• Use compatible paper only
• Do not overfill the tray
• Keep the stack flat
• Do not mix paper sizes/types
• Adjust paper guides to the paper edges

 Incorrect paper loading can lead to jams, misfeeds, and printer errors.
