2. Adjust the rear paper support (5) to the size of paper you are using by gripping the
lugs, tilting and sliding the support forward or backward as necessary.
3. Adjust the side paper guides (6). It is important to adjust the paper guides (5)
correctly to ensure that the paper is not skewed in the print process. Paper jams
may occur if this operation is not carried out correctly.
4. Replace the tray in the printer (7). The external paper level indicator (8) provides a
visual indication of how much paper is left in the tray.
Note
If you have the optional second paper tray (Tray 2) and you are printing
from the first (upper) tray (Tray 1), you can pull out the second (lower) tray
to reload it. However, if printing from the second (lower) tray, do not pull
out the first (upper) tray as this will result in a paper jam.
Configure the media size and media weight for the respective trays in the operator panel.
