Phaser 6125/6130 Color Laser Printer Service Manual 3-81
Error Messages and Codes
6 Check the K Mode Solenoid for
resistance
Disconnect P/J24 from the MCU
Board.
Is the resistance across J24-1 and
J24-2 about 80 to 110-ohm?
Replace the
MCU Board
(page 8-59).
Replace the
Feed Drive
Assembly
(page 8-22).
7 Check that the Feed Drive Assembly is
properly installed. If not, install
correctly.
Does the error still occur when the
printer is powered on?
Go to step 8 Complete
8 Check the connections between the
MCU Board and K Mode Sensor.
Are P/J26 and P/J261 connected
securely?
Go to step 10. Reconnect the
connector(s) P/
J26 and/or P/
J261 correctly,
then go to step
9.
9 Does the error still occur when the
power is turned OFF and ON?
Go to step 10. Complete
10 1. Disconnect J26 from the MCU
Board.
2.Measure the voltage across P26-1
<=> ground on the MCU Board.
Is the voltage about +3.3 VDC?
Go to step 11. Replace the
MCU Board
(page 8-59).
11 1. Remove the Feed Drive Assembly
from the printer (page 8-22), but let
P/J261 and P/J24 remain
connected.
2. Perform the K Mode Sensor test
(page 4-23): Service Mode >
Sensor Test > K Mode Sensor.
During this check, close the Front
Cover.
Does the voltage change, when a piece
of paper is inserted into the gap of the
K Mode Sensor?
Replace the
MCU Board
(page 8-59).
Replace the
Feed Drive
Assembly
(page 8-22).
