Lexmark 640 用户手册

The optional 2000-sheet drawer can be used for plain paper, letterhead or other preprinted paper, labels, or transparencies. 
For trouble-free printing, make sure you:

Do not load print media above the load line. 

Do not fold or crease the paper.

Do not mix sizes or weights in the same source.

Do not open the door or remove any print media when a job is printing or when the operator panel indicator light is 
blinking. Doing so may cause a jam.

Note: Before loading print media in the drawer, you should know the recommended print side of the paper 

you are using. This information is usually on the paper package.

To load the 2000-sheet drawer:

Open the loading door. If the elevator tray is not already in the lowered position, push the elevator button to lower 
the tray.

Flex the sheets back and forth to loosen them, then fan them. Do not fold or crease the print media. Straighten the 
edges on a level surface.
