Staining can occur at the leading edges during duplex printing when feeding postcards or thick paper from the Bypass Tray.

Cause

During feed for duplex printing from the bypass tray, the printed first side is rubbing against the bypass paper feed rollers and peeling off toner.

Action

If smearing or staining occurs at the leading edges within halftone and filled areas when feeding from the bypass tray, switch to paper feed to Tray 1.
