N
Check the installation status of the ATC SENSOR and the
wire between the ATC SENSOR P129 and the MCU PWB
J405 for an open circuit and poor contact. If no problems
are found, replace the ATC SENSOR. (PL6.2)

Check the wire between the DEVE MOTOR J232 and the I/F
PWB J534 for an open circuit and poor contact. If no problems
are found, replace the DEVE MOTOR. (PL1.1)
After checking that no failures are detected during normal
operation, end the Diag.
009-411 TONER MAGENTA NEAR EMPTY
Description
It is time to replace the MAGENTA TONER.
Though a usual display does not need troubleshooting, it may
be required in the following cases:
• Blocked toner
• An operation failure of the Dispense Motor
• When the machine outputs high-density prints
continuously
BSD on : CH9.11 CH9.15 CH9.16 CH9.31C
Procedure
Check that the toner in the DEVE UNIT is even.

Y
N
Repair the DISPENSE MOTOR using Generic Motor
Does Not Rotate Failure FIP. (PL6.1)
Check the Auger Mechanism for toner supply.
Run the
DC922
TONE UP/DOWN.
