Print Engine Operation
Power On/Off Switch
The Power On/Off Switch is located just to the left (or right) of the print engine’s con-
trol panel (see Figure 7 on page 18). When this switch is placed in the ON (1) position,
the POWER light goes ON and the print engine automatically performs a Power On
Self Test (POST). The Liquid Crystal Display validates the steps in the self test.
NOTE: Refer to “Troubleshooting” on page 49 if the print engine stops due to failing
a test in the Power On Self Test.
Control Panel Keys
Refer to Figure 7 on page 18. Specific uses of these keys are explained with each
parameter setting description in “Configuration & Calibration” on page 21.
