Replace the harness with no continuity. 7 PWBA MCU & HVPS continuity 1. Disconnect the P/J11 and P/J24 connector from the PWBA MCU & HVPS. (Refer to Ch4- 4.2.18.1) 2. Check the continuity between P11-17 <=> P24-4. Is the continuity normal between P11-17 <=> P24-4 normal? Replace the PWBA MCU & HVPS. (Refer to Ch4-4.2.18.1) Go to step 8. 8 Harness Assy DRV 1 continuity 1. Disconnect the P/J41 connector from the PWB Drive . 2. Measure the voltage between connectors P41-24 <=> P42-14/15 of the PWB Drive. Is there 5V DC between P41-24 <=> P42-14/15. Replace the Harness Assy DRV 1 . Go to step 9. 9 PWB Drive continuity 1. Disconnect the P/J61 connector from the PWB Drive. 2. Measure the voltage between J61-8 <=> J61-7. Is there 5V DC between J61-8 <=> J61-7. Replace the PWB Drive. (Refer to Ch4-4.2.18.5) Go to step 10. 10 Harness Assy LVNC continuity 1. Disconnect the P/J165 connector from the LVPS . 2. Measure the voltage between P165-1 <=> P165-2. Is there 5V DC between P165-1 <=> P165-2. Replace the Harness Assy LVNC . Go to FIP-DC .ltage between P231-1 <=> P231-3. Is there +5V DC between P/J231-1 <=> P/J231-3? Replace the Sensor Hum Temp. (Refer to Ch4-4.2.7.5) Go to step 6.
Code: 1100, 1101
Description: 1100 ROM checksum error (bit 0 ~ 15) (Font) 1101 ROM checksum error (bit 16 ~31) (Font)
Remedy: 1 Initial setting: • Remove all the optional units and modules related to the electrical system and bring the printer back to the standard status. • Check if all connectors are properly connected to the CONTROLLER PWB. Replace or reinstall the relevant part. Go to step 2. 2 Replace the CODE ROM-DIMM (C309PROG): • Replace the mounted CODE ROM-DIMM. Does the problem still occur? Replace the CONTROLLER PWB. Problem solved.

Code: 1180, 1185
Description: 1185 Unsupported ROM module 1200 EEPROM write error
Remedy: 1 Initial setting: • Remove all the optional units and modules related to the electrical system and bring the printer back to the standard status. • Check if all connectors are properly connected to the CONTROLLER PWB. Replace or reinstall the relevant part. Go to step 2. 2 Checking the DIMM: • Insert the DIMM in the socket until it is locked securely. NOTE: Since the DIMM has the right direction and location for insertion, be sure to insert it in the correct direction and location. • Check if the DIMM is available for this printer, AcuLaser C4000. In cases other than above, replace the CONTROLLER PWB. Replace or reinstall the relevant part. Problem solved.
