Step
Checking the connectors of the K Mode Sensor in the
DRIVE ASSY PH for connection
Check the connections between the PWBA MCU and K
Mode Sensor.
Are P/J26 and P/J261 connected correctly?
8
Does the error still occur when the power is turned OFF and
9
ON?
Checking the HARNESS ASSY KSNR REGCL MG AIO for
continuity.
10 Disconnect J26 from the PWBA MCU.
Disconnect J261 from the K Mode Sensor.
Is each cable of J26 <=> J261 continuous?
Checking the power to the K Mode Sensor.
Disconnect J26 from the PWBA MCU.
11
Is the voltage across P26-1pin <=> ground on the PWBA
MCU, about +3.3 VDC?
Checking the K Mode Sensor for operation.
Remove the DRIVE ASSY PH from the printer once, but P/
J261 and P/J24 should be connected.
Checked by [Digital Input] - [K Mode Sensor] in [IOT Diag] of
12
diagnosis.
During this check, close the COVER ASSY FRONT MG.
