Main code Sub code Description Ref. Page
08 01 Developing bias voltage output. After delivering the output, the machine automatically goes into the sub
code input wait state.
This is the test command used to check the developing bias voltage. The developing bias voltage is
turned on for 30 seconds.
Standard developing bias setting is –300VDC.
[7]-2(3)
02 Main (charge) corona output [ME]. After delivering the output, the machine automatically goes into the
sub code input wait state.
Standard manual exposure mode main corona grid voltage is –860±15V.
[7]-5-(D)
This is the test command used to check the main corona variance between the front and rear sides.
The corona output continues for 30 seconds.
• The main corona variance must be within 8µA between the front and the rear.
03 Main corona output [PE]. After delivering the output, the machine automatically goes into the sub code
input wait state.
Standard photographic mode main corona grid voltage is –610±15V.
[7]-5-(D)
04 Main corona output [TSM]. After delivering the output, the machine automatically goes into the sub code
input wait state.
Standard TSM main corona grid voltage is –755V±15V.
[7]-5-(D)
06 Transfer corona output [TSM]. After delivering the output, the machine automatically goes into the sub
code input wait state.
This is the test command used to check the transfer corona output (THV). The transfer corona output
continues for 30 seconds.
[7]-4-(B)
Standard transfer corona output is –57µA±4µA (F/R difference: Max. 5µA).
07 Separation corona output. After delivering the output, the machine automatically goes into the sub code
input wait state.
This is the test command used to check the separation corona output (SHV). The separation corona
output continues for 30 seconds.
[7]-6-(E)
Standard separation corona output is –100±10 V.
09 02 ADU sensor check test command ON/OFF state of each sensor can be manually checked.
When the sensor turns on, the display reverses.
