Item
Indicates the TD sensor output:
V
: Current detected voltage
T
Initial: TD sensor output at last process
control data initial setting.
Previous: Previous detected voltage
V
: Last detected voltage during ID
TP
sensor compensation.
V
: Toner supply level target voltage.
REF
Indicates the ID sensor output
V
: ID sensor output while detecting
SGP
the bare drum surface (with dev.
bias and development roller
rotation).
V
: ID sensor output while detecting the

ID sensor pattern image.
V
: ID sensor output while detecting the
SG
bare drum surface (without
development bias and without
development roller rotation).
Indicates the drum potential while
detecting the ID sensor pattern
(grid voltage = –700 V).
Function
during ID sensor
compensation.
