What to check first

Step-by-step checks

    Consumable check

    Open the duplexer at the rear of the printer and remove jammed paper carefully.

    Start with the official recovery step before moving on to parts or deeper servicing.

  2. 2

    Safe first step

    Check for scraps near the rear door and duplex path before closing it.

  3. 3

    Consumable check

    Retry with flatter paper or one-sided printing if duplex jobs keep failing.

Background

Diagnosis

Likely causes

Most common

Common

Possible

Curled or unsuitable media failed during duplex reversal.
