In the Printer Diagnostic tests, use
Engine Diag > Motor Test > K Mode
Solenoid
.
During this check, close the Front Cover.
Do you hear the K Mode Solenoid click
when you perform the K Mode Solenoid?
Go to step 3. Go to step 4.
3
Reseat the Feed Drive Assembly.
Does the error still occur when the power
is turned Off and On?
Go to step 8. Complete.
4
Check the connection between the MCU
Board and K Mode Solenoid.
Is P/J24 connected correctly?
Go to step 6. Reconnect the
connector P/
J24 correctly,
then go to
step 5.
5
Does the error still occur when the power
is turned Off and On?
Go to step 6. Complete.
6
Disconnect J24 from the MCU Board.
Is the voltage across P24-1 <=> ground
on the MCU Board, about +24 VDC when
the Interlock Switch (Interlock Harness
Assy) is pushed?
Go to step 7. Replace the
MCU Board.

7
Disconnect P/J24 from the MCU Board.
Measure the resistance between J24-1
and J24-2.
Does the resistance measure about 80 to
110-ohm?
Replace the
MCU Board.
