1. Installation
Loading Printing Paper
You can load letter or legal size paper in the paper tray. Recommended paper
weight is 20-lb. Copy Bond. The maximum number of sheets is as follows:
Letter size: Approx. 100 sheets (20-Ib. copier paper at room temperature;

Make sure the stack edges are even.
2 Insert the stack of paper into the tray, PRINT SIDE UP .
•If paper remains in the tray, take it out and combine it into a single stack
with the new paper.
•Be sure to load the paper so that printing takes place on the print side of
the paper. Printing on the reverse side may result in poor print quality.
• GENTLY LOAD PAPER INTO THE PAPER TRAY .
• DO NOT FORCE IT DOWN INTO THE FEED SLOT .
Note: Do not use paper that has already been printed on, or paper that is curled.
The stack

doing so may damage the machine.
Note: If your area experiences a high incidence of lightning or power surges,
we recommend that you install surge protectors for the power and telephone
lines. Surge protectors can be purchased at most telephone specialty stores.
“CHECK CARTRIDGE” normally
appears in the display the first
time you plug in the machine.
This message appears until you
