3.7.1 What is Test Print?
In order to check the engine operation, you can print a test pattern embedded in a
PWBA MCU without activating the controller. If no problem is found during printing
the pattern, the cause of the trouble may be on the main controller (BOARD ASSY,
MAIN) side.
3.7.2 How to Print
1. Remove the two SCREW KNURLINGs that secure the COVER OPTION to the
main unit, and remove the COVER OPTION. (See
Figure 3-6 (p.154).)
2. Load papers in the standard lower paper cassette or in the MP tray, and turn the
power on. Cleaning cycle (process control) will start.
3. Confirm that “Ready” appears on the LCD panel after the cleaning cycle is
completed, short the unmounted circuit pattern R686 (just below CN601) on the
BOARD ASSY, MAIN with a blade of a flatblade mini screwdriver. See
Figure
3-7 (p.154).
