Lexmark X215 Paper Tray Differences

Later machines have a feature added that makes early paper trays incompatible with later chassis. An early paper tray in a later chassis will not close properly, resulting in pickup failures.

The added feature is automatic lowering and latching of the paper tray's paper platform as the tray is withdrawn.

The feature consists of a linear cam in the chassis' left side way, and a corresponding actuator attached to the left side of the tray's paper platform. When the tray is withdrawn, the cam strikes the actuator and forces the paper platform down. Owing to the cam's position, it interferes with complete closure of early trays.

There appears to be no retrofit available.

Lexmark X215 'Door Open' Message

The cover open switch is a lever-operated microswitch at the right front corner of the power supply PCA. A black plasic lever on the chassis' right side actuates it when the front door is closed.

If you're getting false 'door open' messages after having removed and reinstalled the electronics pan, it's probably because you got the switch's lever over top of the black plastic lever instead of underneath it as you were putting the electronics pan in place.

Fortunately, there's no need to take the electronics pan back out. Just remove the rear and the right side covers. The black plastic lever will be accessible. Take out the lever's screw, correct the lever's position and reassemble.
