Step
Possible causative parts:
No Paper Sensor (PL3.2.13)
HARN ASSY L SIDE (PL10.4.18)
PWBA MCU(PL10.7.7)
Checking the operation
1 Did you insert the paper into the paper cassette at side 2
printing?
Checking the customer operation
2 Did you insert the paper cassette into the printer until it
stopped?
Checking the customer operation
3
Did you set the correct paper to the paper cassette?
Checking the No Paper Sensor
Does the number on the screen increase by one, when the
actuator (ACTUATOR NO PAPER) of the Cassette No
4
Paper Sensor (SENSOR PHOTO) is operated?
Checked by [Digital Input]-[DI-01] of the [IOT Diag] on the
[Printer] of the diagnosis.
Checking the connectors of the SENSOR PHOTO
(Cassette No Paper Sensor) for connection
5 Check the connections between the PWBA MCU and
SENSOR PHOTO.
Are P/J23 and P/J234 connected correctly?
Checking the HARN ASSY L SIDE for continuity
Disconnect J23 from the PWBA MCU.
6
Disconnect J234 from the SENSOR PHOTO.
Is each cable of J23 <=> J234 continuous?
Checking the power to the SENSOR PHOTO
Disconnect J23 from the PWBA MCU.
7
Is the voltage across P23-9pin <=> ground on the PWBA
MCU, about +3.3 VDC?
