FIP-1.93 093-925 / 093-950 / 093-951 / 093-952: IOT Toner (YMCK) CRUM Comm Error
Step Check
Remedy
Yes No
Possible causative parts:
TONER CARTRIDGE (Y) (PL5.1.24)
TONER CARTRIDGE (M) (PL5.1.23)
TONER CARTRIDGE (C) (PL5.1.22)
TONER CARTRIDGE (K) (PL5.1.21)
CONNECTOR CRUM (PL5.1.14)
PWBA MCU (PL8.3.6)
HARN ASSY TONER CRUM (PL5.1.26)
1
Checking the TONER CARTRIDGE (Y, M, C or K) for
installing.
Reseat the TONER CARTRIDGE (Y, M, C or K).
Does the error still occur when the power is turned off and
on?
Go to step 2. End of work.
2
Checking the connectors for connection.
Check the connections between the PWBA MCU and
CONNECTOR CRUM (Y, M, C or K).
Are P/J31 and P/J311(Y) / P/J312 (M) / P/J313(C) / P/J314
(K) connected surely?
Go to step 4.
Reconnect the
connector(s)
surely, then go to
step 3.
3
Does the error still occur when the power is turned off and
on?
Go to step 4. End of work.
4
Checking the HARN ASSY TONER CRUM for continuity.
Disconnect P/J11 from the PWBA MCU.
Disconnect P/J311(Y) / P/J312 (M) / P/J313(C) / P/J314 (K)
from the CONNECTOR CRUM (YMCK).
Is each cable of P/J31 <=> P/J311(Y) / P/J312 (M) / P/
J313(C) / P/J314 (K) continuous?
Go to step 5.
Replace the
HARN ASSY
TONER CRUM.
5
Checking the output power of CONNECTOR CRUM (Y, M, C
or K).
Disconnect P/J31 on the PWBA MCU.
Is the voltage across ground <=> J31-3(Y)/7(M)/11(C)/ 15(K)
pin on the PWBA MCU, about +3.3VDC?
Replace the
DISPENSER
ASSY. (Refer to
REP5.1.)
Go to step 6.
6
Checking after the TONER CARTRIDGE (Y, M, C or K).
Replace the TONER CARTRIDGE (Y, M, C or K).
Does the error still occur when the power is turned off and
on?
Replace the KIT
PWBA MCU
(Refer to
REP8.10.)
End of work.
