Initial issue
9-393 New Toner Cartridge (Y)
When a new Toner Cartridge was installed, the level of the New Cartridge Detect Switch (Y)
remained L when it should be changed to H by the Dispense Motor drive.
Initial Actions
• Re-install the Toner Cartridge ensuring that the Dispense Motor and the Toner Cartridge
are engaged.
• Check that the New/Old Detection Switch (metal part) at the rear of the Toner Cartridge is
raised. If the New/Old Detection Switch is not raised, lift it up, then set the value of NVM
location 752-683 (Accumulative Dispense Time Value Y) to 0.
• Check that the Dispense Motor is operating; check dC330 [009-001, Dispense Motor (C)].
If the motor energizes, even briefly, check for clumping in the cartridge. Turn the auger
gear by hand and/or shake the cartridge to loosen the toner.
Procedure
Disconnect P/J405 from the MCU PWB. The fault has cleared.
YN
Replace the MCU PWB. (PL 13.1).
Remove the yellow toner cartridge and check the Dispense Motor Assembly for wear or dam-
age.
Disconnect FS180 and FS181 at both edges of the New Cartridge Detect Switch (Y).
Check continuity at both edges of the New Cartridge Detect Switch (Y). There is continuity
when the Switch is not engaged.
YN
Check the wire between the connector J405-B18 and FS181 on the New Cartridge Detect
Switch (Y) for a short circuit to the frame (Figure 1).
Replace the New Cartridge Detect Switch (Y) (PL 6.1).

9-408 Waste Toner Cartridge Near Full
The Waste Toner Cartridge is nearly full. This fault requires service only if the message
appears before the Toner Cartridge is depleted.
Initial Actions
Replace the Waste Toner Cartridge. Check the Full Toner Sensor for contaminants.
Procedure
If the problem persists, go to the 9-358 RAP.
