Lexmark W810 用户指南

Paper feeding problems in the mailbox may occur if the height of the mail-
box is not equal to that of the printer. Pull the mailbox away from the 
printer and look at the position of the transport unit to determine if the 
mailbox is at the correct height.

If the transport unit appears level, as shown in the following figure, the 
mailbox and printer are correctly aligned. See page 19 for other possible 
sources of paper feeding problems. 

If the transport unit is tilted either up or down, follow the steps in this sec-
tion to adjust the mailbox’s height.
