Problem Description:
Primer Shutdown Error.
Corrective Action:
Try the following:
1. Check that the Primer Stepper-Motor Cable is NOT broken or damaged and that the Primer Arm moves freely from side to side.
2. Replace the Service Station.
3. If the Error Code continues, replace the Main PCA.
Warning:
Only replace one component at a time and check if the error has gone before replacing another component. Using this procedure you will be able to determine exactly which component failed.
Problem Description:
Primer not calibrated or the calibration settings have been lost.
Corrective Action:
Try the following:
1. Perform the Service Station Calibration.
2. Replace the Service Station Assembly.
Problem Description:
Print Mask could not be generated. The mask generation algorithm could not generate the print mask. Possible causes are memory corruption, print mode definition incompatible with mask restrictions (if using an external RIP). The cause is not likely to be the Printhead because if it was, the Printhead would be marked as XX21 REPLACE.
Corrective Action:
Try the following:
1. Re-boot the Printer and the error code should not appear again.
2. If the problem continues to appear and the customer is using an external RIP, ask them to try one of the internal print modes by printing from the HP Driver. If the problem disappears, then the RIP print mode was causing the problem and the customer should contact the RIP vendor.
3. Check whether there is a printhead in the XX21 REPLACE status. If there is, replace that Printhead.
4. If there is no Printhead in the XX21 REPLACE status, print the Diagnostic Print to find the Printhead with the failing nozzles.
Problem Description:
Error in Printhead Drop Detection. This error code appears when the Printer detects that the same area of nozzles do not work in different Printheads. The possible causes are either fibres or a piece of paper in the Drop Detector or that the Scan-Axis reference is incorrect.
Corrective Action:
Try the following:
1. Manually recover the Printheads and check whether the error still appears.
2. If the error does appear again, then check that there no fibres or pieces of paper in the Drop Detector.
3. If the error does not appear again, then check that the Scan-Axis stop of the Carriage is not deformed too much (some slight deformation of upto 0.5mm is normal, but if it is bigger than that, then replace the Carriage Assembly and recalibrate the Printer).
4. If the Scan-Axis is OK also, then replace the Drop Detector or the Service Station Assembly and recalibrate the Printer
Problem Description:
Drop Detector not calibrated or the calibration settings have been lost.
Corrective Action:
Try the following:
1. Perform the EEROM Backup from the HDD to the Main PCA (select Main PCA replaced).
2. Switch the printer Off and ON again.
3. If the System Error Code continues:
– Perform the Service Station Calibration.
– Replace the Drop Detector Assembly.
– Replace the Service Station Assembly.
Warning:
Only replace one component at a time and check if the error has gone before replacing another component. Using this procedure you will be able to determine exactly which component failed.
Problem Description:
Drop Detector Failure.
Corrective Action:
Try the following:
1. Check that the Drop Detector Cable is NOT broken or damaged.
2. Check that the Drop Detector cable is correctly connected to the Service Station Cable.
3. Remove the Drop Detector and make sure that there are no obstacles inside which are blocking the sensor.
4. Replace the Drop Detector Assembly.
5. If the System Error Code continues, replace the Main PCA.
Warning:
Only replace one component at a time and check if the error has gone before replacing another component. Using this procedure you will be able to determine exactly which component failed.
Problem Description:
Unable to detect the Heater – If this error appears, all settings related to the heater will disappear from the front Panel.
Corrective Action:
Try the following:
1. Check that the cable from the Heater to the Main PCA is correctly connected and is NOT damaged.
2. Replace the Heater.
Problem Description:
24 V source test failure.
Corrective Action:
Replace the Main PCA.
Problem Description:
Serial Device ADC test failure.
Corrective Action:
Replace the Main PCA.
Problem Description:
APS Failure.
Corrective Action:
Try the following:
1. Check that the cable from the Ink Supply Station (ISS) PCA to the Ink Supply Station is correctly connected.
2. Check that the Air Pressurization System Sensor Cable is correctly connected and is NOT damaged.
3. Check all the tubes of the APS and make sure they are NOT pinched or damaged.
4. Faulty APS. Replace the APS.
5. If the error code continues, replace the Main PCA.
