HP Deskjet 4640, Officejet 4630 Printers - Paper Jam Error

This document is for HP Deskjet Ink Advantage 4645, 4646, 4648, Officejet 4630, 4631, 4632, 4634, 4635, 4636, and 4639 e-All-in-One printers.
During printing, the printer stops feeding pages and the error message Paper Jam displays on the printer control panel. The control panel might also display a brief description of how to remove the jammed paper.
Paper jams can be real or false. The printer might report a paper jam even when there is no jammed paper. The following steps apply to both real and false paper jams.

Step 1: Look for jammed paper

Paper jams can occur in multiple areas of the printer. If you cannot find the paper jam in one area, continue to the next area until you locate the jam.
If you have checked and removed any jammed paper from each printer area and the error persists, continue to the next step.

Step 2: Clean the paper rollers

Dust, paper fiber, and other debris might accumulate on the paper feed rollers and cause paper jams and paper feed issues.
  1. Turn off the printer if it is not off already.
  2. Disconnect the power cord from the rear of the printer if it is not disconnected already.
    You must disconnect the power cord before reaching inside the printer to avoid risk of injuries or electric shock.
  3. Locate the slots on the left and right sides of the printer.
