Countermeasures in case of E7-91 - 94
In case of E7-9x (11), E7-9x (21), E7-9x (31), E7-9x (41)
Since the automatic memory check executed when E7-91 - 94
occurs is a simplified check, it cannot detect an abnormality with
absolute certainty.
If the added code is (*1), there may be a memory abnormality.
Even if it is not (*1), however, it cannot be said that there is no
abnormality around the memory.

Cause
In case of E7-91 - 94, the memory (DRAM) is
automatically read/written to perform a simplified
check. If an abnormality is detected in that case, the
added code becomes (*1).
Therefore, there is a strong possibility that an
abnormality lies around the memory.
Check and remedy
- Use SIM60-01 (Memory read/write check) to
check to insure that no error occurs.
- Replace the MFPC PWB.
Cause
Mostly because the data inputted to the ASIC for
decoding are broken for some reasons.
There is an abnormality in the process of read/write
of the process data in the memory or the hard disk.
A great noise unexpectedly generated may be the
cause.
For the cases of FAX or Internet FAX reception data,
when broken data are saved, printing is performed
every time when the machine is booted, generating
an error repeatedly. (E7-91)
(To clear the received data, execute SIM66-10.)
Check and remedy
- Check the MFPC PWB to insure that there is no
abnormality.
- When the job at occurrence of an error is FAX
(E7-91), check the installing state of the FAX
control PWB and the SC CARD PWB.
- Perform SIM60-01 (Memory read/write check) to
insure that there is no NG.
- Check the installing state of the MFPC PWB to
insure that there is no abnormality.
- Replace the HDD.
- Replace the FAX control PWB.
- Replace the MFPC PWB.
