- Code: P-14
- Description: Skew correction trouble. The difference between the skew default position setting value and the cumulative amount of skew adjustment values goes over the predetermined value.
- Causes: • IDC sensor/Fr (IDCS/Fr) • IDC sensor/Rr (IDCS/Rr) • Imaging unit/Y,M,C • Drum unit/K • MFP board (MFPB) • PH unit
- Remedy: 1. Check the drive transmission portion of the imaging unit or drum unit and correct as necessary. 2. Clean the contact of the imaging unit or drum unit connector if dirty. 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 connectors of the MFPB for proper connection and correct as necessary. 6. Replace IDCS/Fr or IDCS/Rr. 7. Replace the imaging unit/Y,M,C. 8. Replace the drum unit/K. 9. Replace the PH unit. 10. MFPB F14E conduction check 11. Replace MFPB NOTE • After the PH unit is replaced, reset the skew default position for each color in [Service Mode] -> [Machine] -> [Print Head Skew Adj.] -> [Print Head Skew Adj.] • When this alert code is displayed, according to the list, take actions to address the problem. After the problem is resolved, select [Service Mode] -> [Machine] -> [Print Head Skew Adj.] -> [Print Head Skew Reset] and perform the skew adjustment reset.
- Code: P-21
- Description: Color regist test pattern failure. • During pre-pattern detection, pre-pattern edge (start/ end point of effective area) is not detected within the pre-pattern search area. • During detection of regist pattern at vertical/horizontal direction, pattern edge (start/end point of effective area) is not detected within the pattern search area of each unit.
- Causes: • Transfer belt unit • PH unit • MFP board (MFPB)
- Remedy: 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. Replace the PH unit. 4. Replace MFPB.
- 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)
- Remedy: 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
- Remedy: 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)
- Remedy: 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
- Remedy: 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
