91-676-00 The required voltage or normal adjustment exceeds the maximum on printhead 3.
91-677-00 The required voltage or normal adjustment exceeds the maximum on printhead 4.
NOTE: Faults 91-674-00 to 91-677-00 are raised when a manual
Head Uniformity is performed and an unusually large adjustment is calculated. The routine will
abort without saving changes.
91-812-00 The required voltage adjustment exceeds the maximum on printhead 1.
91-813-00 The required voltage adjustment exceeds the maximum on printhead 2.
91-814-00 The required voltage adjustment exceeds the maximum on printhead 3.
91-815-00 The required voltage adjustment exceeds the maximum on printhead 4.
NOTE: Faults 91-812-00 to 91-815-00 are raised when an automatic
Head Uniformity is performed and errors are detected. The routine will abort without saving
changes.
Procedure
Ensure that the electricity to the machine is switched off while performing tasks that do
not need electricity. Refer to
death or injury. Moving parts can cause injury.
Check the test pattern (TP 1) that was printed for evidence of colour mixing or wrong colours. If
necessary, the test pattern can be printed from dC972, option 3 Head to Head Uniformity.
Colour mixing or wrong colours are evident.
Y N
The best quality, bright white plain paper available must be used for the manual uniformity
calibration, go to dC972
NOTE: Automatic uniformity has no specific media requirements.
The correct media is used.
Y N
Load the correct media, then perform the following
1. Option 3 Head to Head Uniformity - manual.
2. Option 4 TRC Generation - manual.
3. Option 5 Y Dot Position Correction, select all heads.
Perform the following dC972
1. Option 6 Reset Head Uniformity Data.
2. Option 3 Head to Head Uniformity - manual.
