K).
Does the error still occur when the
power is turned Off and On?
Go to step 2. Complete.
2 Check the connections between the
MCU Board and CRUM Connector (Y,
M, C or K).
Are P/J31 and P/J311(Y) / P/J312 (M) /
P/J313(C) / P/J314 (K) seated
securely?
Go to step 4. Reseat the
connector(s)
securely, then
go to step 3.
3 Does the error still occur when the
power is turned Off and On?
Go to step 4. Complete.
4 Check the Toner CRUM Harness Assy
for continuity.
Disconnect P/J11 from the MCU
Board.
Disconnect P/J311(Y) / P/J312 (M) / P/
J313(C) / P/J314 (K) from the CRUM
Connector (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
Toner CRUM
Harness Assy.
