If the error clears, monitor the printer. If it returns immediately, proceed to Step 2. Many users have reported that the error appeared

Look directly at the main drive assembly gear track (located on the left/rear side of the machine). Check for stripped teeth, cracked plastic cogs, or heavy debris stalling rotation.

Pull out any stuck sheets gently using both hands to avoid tearing.
