IMPORTANT: Set paper size dial (3) to the size and orientation of
paper being used (A4 LEF in the example above).
To prevent paper jams:
> Do not leave space between the paper and the guides and rear stopper.
> Do not overfill the paper tray. Capacity depends on the type of paper stock.
> Do not load damaged paper.
> Do not load paper of different sizes or types at the same time.
> Close the paper tray gently.
> Do not pull the paper tray out during printing (except as described below for the
2nd tray).
NOTE
> If you have two trays and you are printing from the 1st (upper) tray, you
can pull out the 2nd (lower) tray during printing to reload it. However, if
printing from the 2nd tray, do not pull out the 1st tray. This will cause a
paper jam.
> For face down printing, make sure the face up (rear) stacker is closed (the
paper exits from the top of the MFP). Stacking capacity is approximately
250 sheets, depending on paper weight.
> For face up printing, make sure the face up (rear) stacker is open and the
paper support is extended fully. Paper is stacked in reverse order and tray
capacity is approximately 100 sheets, depending on paper weight.
> Always use the face up (rear) stacker for heavy paper (card stock, etc.).
Do not open or close the rear paper exit while printing as it may
result in a paper jam.
