13.2 Table Number
Vdc-C/ Vg-C
• When IDC is detected, for plain paper, Thick, and Black, the machine independently displays each Vg or 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.
• Used for troubleshooting of image problems.
• If the value is high: In IDC detection, the image density is judged as low, thus the Vg/Vdc value is to be adjust higher.
