Code: P-22
Description: Color regist adjust failure. • The gap between maximum and minimum value of deviations among each color (the values before averaging) is over the predetermined value. • Average deviation exceeds the predetermined value. • In case the final value of the deviation after stabilization exceeds the predetermined value, it is regarded as failure even if the average deviation is within tolerance.
Causes: • IDC sensor/Fr (IDCS/Fr) • IDC sensor/Rr (IDCS/Rr) • MFP board (MFPB)
Troubleshooting Guides: 1. Slide out the imaging unit or drum/developing unit and reinstall it in position. 2. Reinstall or reconnect IDCS/Fr or IDCS/Rr if it is installed or connected improperly. 3. Check the vertical transport guide for installed position and correct as necessary. 4. Replace MFPB.

Code: P-27
Description: Secondary transfer ATVC failure. An abnormal average value is detected during an adjustment of the second transfer ATVC value.
Causes: • High voltage unit (HV) • MFP board (MFPB) • Image transfer entrance guide • 2nd transfer assy • Transfer belt unit
Troubleshooting Guides: 1. Check the contact between the roller opposed to the 2nd transfer roller in the transfer belt unit and the grounding terminal. Clean the joint or correct if necessary. 2. Check the image transfer entrance guide for proper installation and correct if necessary. 3. Check that the spring does not come off during the pressure operation of the transfer roller and correct if necessary. 4. Check the contact at the joint of the 2nd transfer assy and HV. Clean the joint or correct if necessary. 5. Replace the transfer belt unit. 6. Replace HV. 7. Replace MFPB.

Code: P-33
Description: LD malfunction. The DETOUT signal of the LD drive detected malfunction consecutively for the predetermined frequency.
Causes: • Laser diode/Y (LD/Y) • Laser diode/M (LD/M) • Laser diode/C (LD/C) • Laser diode/K (LD/K) • Laser drive board (LDDB) • PH unit • MFP board (MFPB)
Troubleshooting Guides: 1. Replace the PH unit. 2. Replace MFPB.

Code: P-5, P-28
Description: IDC sensor/Fr failure, IDC sensor/Rr failure. • During IDC sensor light intensity correction, output voltage detected for all eight sample patterns are 3.35 V or more. • During IDC sensor light intensity correction, sensor output voltage for light intensity selected after the correction is under 0.7 V. • During IDC base surface detective control, sensor output voltage detected is under 0.7 V or over 3.35V. • During image stabilization (gamma correction control), detected output value for IDC sensor did not go below threshold (half the value of what is detected by IDC sensor on the belt surface) for three consecutive times (position of the pattern end is not detected). • During image stabilization (gamma correction control), sensor’s output value of each color for hyper 0 gradation after the primary approximation is half the detection level on the belt surface or under
Causes: • IDC sensor/Fr (IDCS/Fr) • IDC sensor/Rr (IDCS/Rr) • High voltage unit (HV) • Transfer belt unit
Troubleshooting Guides: 1. Wipe clean the surface of the transfer belt with a soft cloth, if it is dirty. 2. Replace the transfer belt unit if the transfer belt is damaged. 3. Reinstall or reconnect IDCS/Fr or IDCS/Rr if it is installed or connected improperly. 4. Clean IDCS/Fr or IDCS/Rr if it is dirty. 5. Check the HV connector for proper connection and correct as necessary. 6. Open/close the front door, run an image stabilization sequence, and select [State Confirmation] -> [Level History 1] to check the IDC value. If the value is 1.0 V or less, replace IDCS/Fr or IDCS/Rr. 7. Replace MFPB

Code: P-6, P-7, P-8, P-9
Description: Imaging unit (C) failure, Imaging unit (M) failure, Imaging unit (Y) failure, Drum/Development unit (K) failure. • All density readings taken from the density pattern produced on the transfer belt are 1.0 g/m2 (IDC sensor photo receiver output) or less during max. density adjustment (Vg/Vdc adjustment). • All density readings taken from the density pattern produced on the transfer belt are 4.0 g/m2 (IDC sensor photo receiver output) and more during max. density adjustment (Vg/Vdc adjustment).
Causes: • Imaging unit/Y,M,C • Drum unit/K • Developing unit/K • IDC sensor/Fr (IDCS/Fr) • IDC sensor/Rr (IDCS/Rr) • MFP board (MFPB) • High voltage unit (HV) • Transfer belt unit
Troubleshooting Guides: 1. Select [Imaging Process Adjustment] -> [Max Image Density Adj] and, if the setting value is negative, readjust. 2. Check the drive transmission portion of the imaging unit or drum/developing unit and correct as necessary. 3. Clean the IDC sensor/Fr (IDCS/Fr) or IDC sensor/Rr (IDCS/Rr) window if dirty. 4. Clean the contact of the imaging unit or drum/developing unit connector if dirty. 5. Check the HV connector for proper connection and correct as necessary. 6. Replace the imaging unit/Y,M,C. 7. Replace the drum unit/K. 8. Replace the developing unit/K. 9. Replace the transfer belt unit. 10. Replace HV. 11. Replace MFPB.

Code: S-1
Description: It is detected that the CCD clamp gain adjustment value is faulty.
Causes: • LED exposure unit • CCD unit • CCD board (CCDB) • MFP board (MFPB)
