Solutions

Diagnóstico rápido

If you see the 042-328 message, the Xerox machine is requesting size confirmation. Check that the tray guides are not loose, as this can mislead the size detection sensors.

Solución paso a paso

  1. Pull the affected tray and inspect the paper.
  2. Adjust the side and back guides so they are firm against the paper stack.
  3. Access the control panel and confirm that the detected size matches the physical media.
  4. Save changes and allow the system to perform a detection cycle.

Prevención y mantenimiento

Regularly clean the tray sensors with a dry cloth. Always load paper centered and use compatible media weights so the feed rollers can recognize it correctly.

Cuándo llamar a un técnico

If the error persists after reconfiguring the size, the physical size detection sensors inside the tray bay might be faulty or heavily obscured by debris.
