CHAPTER 5 SERVICE MODE

COPIER>DISPLAY>HV-STS

<HV-STS>

Indicates the measurements taken of voltage/current.

PRIMARY
	Indicates the level of current of primary charging in relation to photosensi-
	tive drum resistance detection control (APVC).
	Unit: µA
	Reference:
	• If 353 µA or less, the drum unit can well be used.
	• 353<485 µA or less, the drum unit may be used without a problem.
	• 485 µA or more, the drum unit should be replaced.
TR
	Indicates the mode selected for the level of current of transfer charging.
	0: transfer constant voltage mode, 1: transfer constant voltage mode (mid),
	2: transfer constant voltage mode (max.), 3: transfer constant voltage mode
	(min.)
BIAS
	Indicates the developing bias DC level (in V)
TR-V
	Indicates the voltage level in relation to transfer charging roller resistance
	detection control (ATVC). (in V)
	Reference:
	1500 to 6000V:	the transfer charging system is normal.
	6001V or more:	the transfer charging roller may have a locking fault.
	1499V or less:	leakage and a transfer charging roller fault
		are possibilities.
		COPIER>DISPLAY>SENSOR
<SENSOR>
Indicates the condition of sensors.
DOC-SZ

Indicates the size of the original detected by the original size sensor.
