Ricoh Aficio 551 Service Code:738

[presstro]

I have problem with Ricoh Aficio 551 service code: 738. Has checked and replaced all motors but still not ok.
Can anyone help?

The Finisher Shift Tray Lift Motor is producing an error.
Have you checked the Stack Height Sensor ?
Also check the Tray itself as there are plastic lugs on the underside of the Tray which break off and cause this fault !

I think I have changed the Finisher Shift Tray Lift Motor(Is it the one on the top left hand corner? Do you have schematic diagram for the Stack Height Sensor? I might have checked that as well.
