91-636-00 The machines print quality maintenance software periodically runs corrective proce-
dures to maintain output quality. This error indicates that these procedures are suspended due
to unrecoverable errors.
This procedure describes how to return a machine to normal operation from fault tolerant
mode, also known as IOD degraded mode. Fault tolerant mode is indicated by the fault code
91-636-00 or by the service code displayed on the UI, refer to the
OF 12 Service Code RAP.
Initial Actions
• Check the PEST error log ( dC123 ) for component failures.
• Check service code displayed on the machine information UI, refer to OF 12 .
• Check the fault history ( dC122 ) to verify fault tolerant mode.
• Check that the EPC memory PWB is installed and seated correctly, PL 3.11 Item 21 .
Procedure
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.
If the IOD sensor detects an imaging problem, one or more attempts are made to correct the
error. If the machine is unable to self-correct specific imaging errors, it suspends operation of
one or more of these normal print-quality adjustment routines. Refer to
Table 1 .
1. Enter dC131 NVM Read/Write and check the status of each routine by entering the NVM
chain-link listed in Table 1 .
2. Check if the routine is in degraded state by checking the status value in dC131 NVM
Read/Write with the value in Table 2 .
3. If the routine is found to be in degraded mode. Refer to Table 2 and perform the actions
as required.
4. Check and clear all related faults listed in dC122 by using the appropriate RAP to return
the status to optimal.
NOTE: The optimal value for all settings is 0.
5. When the routine is returned to optimal, recheck the current status values of the other
routines.
6. Repeat this procedure (1 through to 5) until all the routines report a NVM status value of
0.
