6. Scroll through the Procon “ON” Print items list, find and check that the Items in table 1
are all OK.
7. If any items indicate NG (Fail), check for failed components: Return to Call Flow and
determine component failure, etc. High Voltage Power Supply, ADC Assembly, Developer
Housing, MCU PWB, Photoreceptor, bad Developer Bias.
NOTE: Most values in this table are for reference only. Actual values will vary.
