CHAPTER 5 SERVICE MODE
5-17 T
<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.
