Control-panel boot sequence calibration
If the control panel does not respond when touched, or if it responds erratically, you might need to align
the touch screen. Use the procedure that follows:
1. Turn the power off.
2. Hold down the C and # buttons and turn the power on.
3. Release the C and # buttons when a small square appears in the upper-left portion of the control-
panel display.
4. Use a small pointed device (for example, the tip of a pen) to touch the small square in the upper-
left portion of the control-panel display. A second small square will appear in the lower-right portion
of the control-panel display.
NOTE The first square does not disappear when it is touched. Take care to not touch it a
second time or the calibration procedure will fail.
5. Touch the small square in the lower-right portion of the control-panel display. When you do, the
touch screen alignment is complete and the device returns to power-on initialization.
Engine test (formatter removed)
The engine-test-print page verifies that the print engine is functioning correctly. This test is very useful
for isolating printer problems because the formatter is completely bypassed during an engine test. The
engine-test-print page consists of a full page of horizontal lines across the entire printable area.
1. Turn the device off.
2. Remove the formatter. See
Formatter cover on page 290.
