State Confirm
Item
To display the states of the
input ports of sensors and
switches when the copier
remains stationary.
I/O Check
Used for troubleshooting


when a malfunction or a
misfeed occurs.
To display the Vg/Vb out-
put values calculated for
the image density of the
test pattern (amount of
toner sticking) produced on
Table #
the Transfer Belt during an
AIDC detection sequence.
Used for troubleshooting


of image problems.
To display ATDC (T/C ratio),
AIDC/Regist Sensor output
values, and fusing tempera-
ture.
Used for troubleshooting
Level History 1


of image problems.
To display the intensity
adjustment value of the
AIDC Sensor (Transfer Belt
bare surface level) as
adjusted through the image
Level History 2
stabilization sequence and
ATVC value.
Used for troubleshooting


of image problems.
To display the temperature
and humidity of a specific
location (AIDC Sensor por-
tion) inside the copier and
fusing temperature.
Temp. &
Humidity
Used as reference infor-


mation when a malfunc-
tion occurs.
Purpose
• The operation of each of the switches and
sensors can be checked on a real-time
basis.
• It can be checked as long as the 5-V
power line remains intact even when a
cover is open.
• Reference values
C, M, Y .. Vb: around 400 V
Vg: around 550 V
The higher the humidity, the lower these


values, and the lower the humidity, the
higher these values.
• AIDC: Shows the AIDC bare surface out-
put reading taken last.
• ATDC, fusing temperature: Shows the lat-
est ATDC and fusing temperature data.
<"Reading taken last" means>
• After the last image stabilization
sequence.
• When a test print is produced by pressing
the Start key while Level History 1 is
being displayed.
• AIDC Sensor: Shows the intensity adjust-
ment value (0 to 255) of the AIDC Sensor.
• ATVC (C, M, Y, Bk): Shows the first image
transfer ATVC adjustment value (400 V to
3000 V).
• ATVC (2nd): Shows the second image
transfer ATVC adjustment value (300 V to
5000 V).
• Copier interior temperature: 0 to 100
in 1
• Temperature on Fusing Belt side: 0 to 255
°
C in 1
• Temperature on fusing pressure side: 0 to
255
• Copier interior humidity: 0 to 100% in 1%
increments
• Absolute humidity: 0 to 100 g/cm3 in 1-g/
cm3 increments
