judged.
Remedy Identify■the■cause■of■the■error■whether■it■is■due■to■
mechanical■problem■to■open/close■the■Toner■Cap■or■problem■
at■the■Toner■Container■Cam■HP■Sensor■side.■■
1.■Check■if■the■Toner■Container■Cam■HP■Sensor■is■soiled■
and■the■installation■of■the■sensor.■■
2.■Rotate■the■Set-on■Drive■Shaft■a■little■with■the■attached■
tool,■and■check■the■service■mode■(COPIER>■I/O>■DCON>■
P024■bit7)■to■see■that■the■output■value■of■the■sensor■is■
changed.■■
Since■it■is■difficult■to■check■the■screen■while■rotating■it,■
repeat■the■operation■to■rotate■it■a■little■and■check■the■screen■
until■the■value■is■changed.■■
If■it■is■normal,■the■output■value■of■the■sensor■is■changed■
when■opening/closing■the■Toner■Cap.■Even■if■it■is■normal,■be■
sure■to■perform■step■4■and■later■steps.■■
2-1.■If■there■is■an■error■in■rotation■of■the■Set-on■Drive■Shaft,■
check■the■drive■system■such■as■gears.■■
If■it■is■damaged,■replace■the■Set-on■Drive■Unit■and■then■
perform■step■4■and■later■steps.■■
2-2.■When■the■Set-on■Drive■Unit■is■not■driven■although■the■
Set-on■Drive■Shaft■rotates,■check■if■it■is■driven■by■removing■
the■Hopper■Unit.■■
If■it■is■not■driven,■replace■the■Hopper■Unit■and■then■perform■
step■4■and■later■steps.■■
2-3.■When■the■output■value■of■the■sensor■is■not■changed■
