Definition
From when the power
is turned on until
when the application
of the primary charg-
ing AC bias is started
and stopped.
After the end of
WAIT, unit the Start
key is pressed.
After a press on the
Start key, until the
leading edge is de-
tected by the paper
leading edge sensor.
From when the paper
leading edge sensor
detects the leading
edge of paper to 0.5
sec after it detects the
trailing edge of paper.
From when printing
ends until the main
motor stops.
Purpose
The machine’s mechanical
and electrical states are
checked.
The machine is ready for a
print command.
The machine starts up pro-
cess conditions and picks up
paper for printing.
The DC controller PCB gen-
erates the BD0* signal, and
the image processor PCB
sends VD0* signal and VD0
signal, thereby forming a la-
tent image on the photosensi-
tive drum and turning it into
a toner image.
The drum surface is made
free of potential and the
transfer charging roller is
cleaned.
Remarks
A check is made on the presence/absence of
a cartridge and for paper remaining inside
the machine. The machine also shifts the
WAIT state when the power ON and, in
addition, the toner bottle fitted, the reader
unit and the toner supply cover are put back,
or after returning from ESS mode.
If a shift is from last rotation of
printing on LTR or larger, the fix-
ing heater is subjected to rest heat-
ing temperature control for 5 sec.
The fixing heater is subjected to
temperature control (start-up tem-
perature control, paper passage
temperature control); scanner ro-
tation speed adjustment and
ATVC control are executed.
After last rotation, the machine shifts
to standby to wait for a print com-
mand, in response to which it imme-
diately shifts to initial rotation.
