T644 Default Paper Source Problem

On the left side, near the pichup roller, of the tray there should be a "flag" hanging down in the elips hole. See if it is hanging down or stuck in the "up"position.If so pul it down and the machine should work fine again.

Lexmark T644 Drawer 2 Missing error message but drawer 2 is in place. Drawer 2 always has problems pulling form form drawer when printing from drawer 2.

If job prints from the wrong tray or on the wrong paper or specialty media, this is an indication that the operator panel menu settings do not match the media loaded in the tray.

Make sure the Paper Size and Paper Type specified in the printer driver match the paper size and type in the tray.

900,83 service rip software
