Table Number

Functions • To display the Vg/Vdc output values calculated for the image density of the test pat-
tern (amount of toner sticking) produced on the Transfer Belt during an AIDC detec-
tion sequence.
• Reference values: C, M, Y K Vdc: around 390 V, Vg: around 550 V
Use • Used for troubleshooting of image problems.
Setting/ • If the value is high, correct so that the image density becomes low.
Procedure • If the value is low, correct so that the image density becomes high.
10.12.3 Level History1
Functions • To display TCR (T/C ratio), IDC/Regist Sensor output values, and fusing temperature.
Use • Used for troubleshooting of image problems.
Setting/ • TCR-C/-M/-Y/-K: Shows the T/C output reading taken last.
Procedure • IDC1/IDC2
• Temp-Heat
• Temp-Press.
"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.
10.12.4 Level History2
Functions • IDC Sensor (Transfer Belt bare surface level) as adjusted through the image stabili-
zation sequence and ATVC value.
Use • Used for troubleshooting of image problems.
Setting/ • IDC Sensor: Shows the intensity adjustment value (0 to 255) of the IDC Sensor.
Procedure • ATVC (C, M, Y, K): Shows the first image transfer ATVC adjustment value
• ATVC (2nd)
