Temp. & Humidity
Functions
• When IDC is detected, for plain paper, Thick, and Black, the machine independently
displays each Vg/Vdc output value that is calculated based on the density (toner
amount stuck on the belt) of the test pattern created on the transfer belt.
• Reference values: C, M, Y K Vdc: around 400 V, Vg: around 500 V
Use
• Used for troubleshooting of image problems.
Setting/
Procedure
• If the value is high, correct so that the image density becomes low.
• If the value is low, correct so that the image density becomes high.
Functions
• To display TCR (T/C ratio), IDC/registration sensor output values, and fusing temper-
ature.
Use
• Used for troubleshooting of image problems.
Setting/
Procedure
• TCR-C, -M, -Y, -K
: Shows the T/C output reading taken last.
• IDC1/IDC2
: Shows the latest IDC data.
• Temp-Heat
: Displays the latest temperature of the heating roller.
• Temp-Press
: Displays the latest temperature of the pressure roller.
• IDC Sensor Adjust 1/2 : Shows the intensity adjustment value (0 to 255) of the IDC
sensor.
• ATVC-C, -M, -Y,- K
: Shows the first image transfer electric current adjustment
value (5 to 40
P
A).
• ATVC-2nd
: Shows the second image transfer ATVC adjustment value
(300 to 4800 V).
“Reading taken last” means
• Density of toner of the latest image.
• When a test print is produced by pressing the Start key while level history 1 is being
displayed.
Functions
• To display the temperature and humidity of a specific location (AIDC sensor portion)
inside the machine and fusing temperature.
Use
• Used as reference information when a malfunction occurs.
