How to Fix HP LaserJet Pro M404dn Paper Jam in Tray 2

Quick Diagnosis

This error occurs when the printer's pickup roller fails to feed paper from Tray 2 into the registration assembly due to dirty roller surfaces, worn separation pads, or misaligned paper guides inside the cassette.

Step-by-Step Resolution

  1. 1

    Turn off the printer, unplug the power cord, and pull the Tray 2 cassette completely out of the printer.

  2. 2

    Inspect the interior cavity of Tray 2 and remove any jammed or torn paper pieces using both hands to avoid tearing.

  3. 3

    Locate the rubber pickup and separation rollers inside the top of the tray cavity and wipe them with a lint-free cloth dampened with distilled water to remove paper dust.

  4. 4

    Examine the paper cassette tray to ensure the side and rear paper guides are clicked into the slots corresponding to your exact paper size.

  5. 5

    Slide the tray back in, plug the printer back in, power it on, and perform a physical hard reset by unplugging the cord once during boot-up if the error remains.

Alternative Causes & Edge Cases

  • On the LaserJet Pro M402dn, the solenoid controlling the pickup roller clutch can become sticky, causing continuous feeding and repeated Tray 2 jams.
  • On the LaserJet Enterprise M506, the separation roller spring mechanism in Tray 2 can fatigue, failing to apply enough upward force to feed paper.
