The path between the sub hopper and the developing assembly is clogged with toner.

The developing assembly toner sensor
detects the absence of toner, while the
sub hopper toner sensor detects the
presence of toner. With the developing
clutch turned on, the hopper feedscrew
motor is rotated for 1 sec intermittently
194 times; still, the developing assembly
toner sensor does not detect the presence
of toner.

FK2-0358

Replace the developing assembly toner
sensor. Replace the sub hopper toner sensor.
Replace the DC control PCB.

Need to move inner finisher if you have one to get sub-hooper sensor.Second one is on developer.Sensors are the same.

Good luck.

sensors output can be checked at the DC Controller PCB

Inspect the toner motor drive and the auger mechanism for any foreign object damage

How you can check sensors for developer and sub hooper from service mode please?

E020-0000 // Recovery Sequence
The machine is not equipped with a mechanism to detect the replacement of its toner cartridge, but is designed to execute toner recovery sequence in response to the following, assuming that the cartridge has been replaced:
1. the front cover has been opened and closed after the machine has detected the absence of toner inside the toner cartridge and the developing assembly.
2. the machine has been turned off and then on after it has detected the absence of toner inside the toner cartridge and the developing assembly.
The machine's recovery sequence is as follows:
1. the machine rotates the toner cartridge motor. (intermittently by rotating it for 3 sec and stopping it for 2 sec)
2. if the toner level sensor inside the sub hopper detects the "presence of toner," the machine stops the recovery sequence.
3. after repeating the foregoing intermittent operation 20 times and if the toner level sensor inside the sub hopper still does not detect the "presence of toner," the machine will assumes that the toner cartridge has not been replaced and cause the toner cartridge motor to stop.

Thanks a lot!

some times gear of the the cylinder broken it happen once with me .
