Initial Actions
WARNING
Ensure that the electricity to the machine is switched off while performing tasks that do
not need electricity. Refer to
GP 14 . Disconnect the power cord. Electricity can cause
death or injury. Moving parts can cause injury.
CAUTION
Use care when opening the marking unit drawer when hot. Ink can spill from the ink reservoir
located at the back of the drawer if opened with too much force. Ink cross-color contamination
could also occur.
CAUTION
Do not touch the exposed face of the printheads. Surface contamination or minor damage can
destroy the printhead. Printheads must only be cleaned by a purge cycle.
• Check the harness leading to the indicated printhead.
• Check for damage to surrounding harnesses.
Procedure
All 4 fault codes are recorded in the fault history, dC122 .
Y N
Enter
dC972 and run the Printhead Uniformity test. The test completes successfully.
Y N
Go to
WD 9.5 , WD 9.6 , WD 9.7 , WD 9.20 and WD 9.21 . Check all connections:
• PJ101, Printhead PWB .
• PJ201, PJ301, PJ902, PJ904, IME Controller PWB .
Install new components as necessary:
•
Printhead, PL 91.20 Item 2 .
• IME controller PWB, PL 92.10 Item 1 .
Check the system grounding, refer to GP 7 . The system grounding is good.
Y N
Correct any system grounding issues,
GP 7 , then retest.
Check the ribbon cables from the IME controller PWB for abrasions. Install a new ribbon
cable,
PL 92.10 as necessary. If the error persists, install a new printhead, PL 91.20 Item
2 .
NOTE: Calibration of the registration / preheat assembly, dC625 is only required when:
• The registration / preheat assembly is removed or replaced,
• The horizontal transport assembly is removed or replaced.
Calibration of the registration / preheat assembly is NOT required when:
• A printhead is replaced.
• The IOD assembly is removed or replaced.
Install a new IME controller PWB, PL 92.10 Item 1 .
91-630-00 IOD Scan Process Failure RAP
91-630-00 The IOD scan process has failed.
The IOD scans a target on the drum to optimize print quality and to check for missing jets. Dur-
ing this scanning process, the drum with the target on it moves over the stationary scan bar of
the IOD. The image is scanned multiple times. Each scan is initiated by a signal from the drum
encoder. If a lower than expected number of scans is encountered, this fault is raised.
Initial Actions
WARNING
Ensure that the electricity to the machine is switched off while performing tasks that do
not need electricity. Refer to
GP 14 . Disconnect the power cord. Electricity can cause
death or injury. Moving parts can cause injury.
WARNING
Take care during this procedure. The drum will become hot during normal operation.
Check the harness and the plug connections to the drum drive motor and the drum position
encoder.
Procedure
Go to dC122 Fault History and dC123 PEST Fault History. Check for drum drive faults occur-
ring at the same time as the current 91-630 fault. A drum drive related fault was declared.
Y
N
Refer to
WD 1.1 and WD 9.1 . Check the drum drive motor and the drum position encoder.
Install the following components in the listed order. After the installation of each compo-
nent perform the
dC971 routine, then check for the 91-630-00 fault. Continue with compo-
nent installation until the 91-630-00 fault is cleared, then go to SCP 5 Final actions.
1. Install a new drum position encoder assembly, PL 94.20 Item 8 .
2. Install a new drum belt, PL 94.20 Item 2 . Clean the drum drive pulley with IPA.
3. Install a new drum driver PWB, PL 1.15 Item 4 .
4. Install a new drum drive motor, PL 94.20 Item 6 .
If the fault is still present then install a new IME controller PWB, PL 92.10 Item 1 .
The fault may be intermittent, check for damaged wiring or loose connectors. Repair the
wiring as necessary,
REP 1.1 .
When all faults are cleared, go to SCP 5 Final actions.
Refer to the appropriate RAP and follow the procedure to rectify any other fault. After complet-
ing the RAP perform
dC971 Head to Head Alignment adjust. Follow the on screen instructions
and run the routine. If a 91-630-00 fault occurs then return to the start of this procedure. If the
fault is cleared then go to
SCP 5 Final actions.
