Code: 009-925
Description: Waste Toner Cartridge Installation The Waste Toner Cartridge was not installed correctly.
Remedy: There is +5 VDC from J408-5 on the Engine Control Board (MCU PWB) to GND. Y↓N→There is +5 VDC from FS135 on the Waste Toner Cartridge Interlock Switch to GND. Y↓N→Check the wire from J511B on the +5 VDC LVPS to FS135 on the Waste Toner Cartridge Interlock Switch. There is +5 VDC from FS135 on the Waste Toner Cartridge Interlock Switch to GND. Y↓N→Replace the Waste Toner Cartridge Interlock Switch (PL 4.1). Check the wire between J511B on the +5 VDC LVPS and FS134 on the Waste Toner Cartridge Interlock Switch and the MCU PWB J408-5 for an open circuit or poor contact. Check the connector J408-5 between the MCU PWB and GND. If no problems are found, replace the Engine Control Board (MCU PWB) (PL 13.1).

Code: 009-926
