FIP-1.54 041-340: IOT NVRAM Error
NOTE
If the error occurred after replacing the PWBA MCU, transfer the internal data of the old
PWBA MCU to a new one.
*1: Though some kind of foreign noise would be possible cause, go to FIP Electrical Noise in Other FIP
and check, to make sure.
Step
Check
Remedy
Yes
No
Possible causative parts:
PHD ASSY (PL4.1.21)
PWBA MCU (PL8.3.6)
PWBA EEPROM (XPRO) (PL8.3.4)
HARN ASSY PHD XPRO (PL9.1.11)
1
Does the error still occur after several ON/OFF procedures
of the power?
Go to step 2.
End of work. *1
2
Checking after resetting the PHD ASSY and TONER
CARTRIDGEs.
Reseat the PHD ASSY and four TONER CARTRIDGEs.
Does the error still occur when the power is turned OFF and
ON?
Go to step 3.
End of work. *1
3
Checking after resetting the PWBA MCU.
Reseat the PWBA MCU.
Does the error still occur when the power is turned OFF and
ON?
Go to step 4.
End of work. *1
4
Checking the connectors for connection.
Check the connections between the PWBA EEPROM and
PWBA MCU.
Are P/J 144, and P/J 42 connected surely?
Go to step 6.
Reconnect the
connector(s) P/
J42 and P/J144
surely, then go to
step 5.
5
Does the error still occur when the power is turned OFF and
ON?
Go to step 6.
End of work.
6
Checking the HARN ASSY PHD XPRO for continuity.
Disconnect J42 from the PWBA MCU.
Disconnect J144 from the PWBA EEPROM (XPRO).
Is each cable of J42 <=> J144 continuous?
Go to step 7.
Replace the
HARN ASSY PHD
XPRO.
7
Checking the power to the PWBA EEPROM (XPRO).
Disconnect J42 from the PWBA MCU.
Is the voltage across P42-3pin <=> ground on the PWBA
MCU, about +3.3 VDC?
Replace the
PWBA EEPROM
(XPRO).
Go to step 8.
8
Checking after replacing the PWBA MCU.
Replace the KIT PWBA MCU. (Refer to REP8.10.)
Does the error still occur when the power is turned OFF and
ON?
Go to Electrical
Noise.
End of work.
