Item
Indicates the exposure lamp voltage
(ID Level 4) decided during process
control data initial setting.
Indicates the toner supply level by
image area ratio on an original surface.
This data changes at every copy
through fuzzy control.
Indicates the TD sensor output:
VT: Current detected data
Initial: TD sensor output at last process
control data initial setting.
Previous: Previous detected data during
VTP:
VREF:
Indicates the ID sensor output
VSGP: ID sensor output while detecting
the bare drum surface (with dev. bias
and development roller rotation)
VSP: ID sensor output while detecting
the ID sensor pattern image
VSG: ID sensor output while detecting
the bare drum surface (without
development bias and without
development roller rotation)
Function
