Too far to left margin on 4300TN

[woodss]

The left margin is too far to the left, to point nearly off the page, even on a engine test page and configuration, where the lines normally is blank.
Paper guides are set right, and problem does not occur in tray 1, that eliminates laser scanner and registration assembly.

Laser Assembly?
Paper Feed Assembly?
Paper Registration Assembly?

never seen this .. but would assume it to be feed since tray one is correct... have you checked the print driver? What OS? I know in some drivers you can adjust the margins inside of the driver... is this single side or duplex?
