4. Operation confirmation

1) Load paper in the lower cassette.
2) Insert the power plug into the outlet and the printer, then turn the power switch ON.

After the printer enters STANDBY mode, press the test print switch to make a test print.
Check that the density of the output image is correct

3) Clean around the printer and ensure that it is ready for use at anytime.

5. Operation precautions

1) Turn ON the power of external equipment then the printer. Turn the power OFF in the

reverse sequence. If the power of external equipment is turned ON/OFF while the printer is
ON, noise may be transmitted through the connection cable between the external equipment
and the printer, and error may occur on the printer.

2) Turn off the power of both the printer and the external equipment before plugging/unplug-

ging the connector between the two. Doing so while the power is ON could cause malfunc-
tions.
