T3: The timing is corrected to 0 again (correction 2) when the image process
preparation period starts. This timing differs depending on the selected
paper feeding station.
Paper Feeding StationBlack Dev. Unit
Upper Paper Tray172ms
Lower Paper Tray728ms
By-pass Feed Table305ms
Paper Tray - 11,728ms
Paper Tray UnitPaper Tray - 22,284ms
Paper Tray - 32,840ms
T4: The charge corona turns on 330ms after correction 2. If the toner density
is low, the toner supply clutch turns on at this timing.
T5: The development bias changes from the non-image bias to the image
bias 930ms (641ms for color) after correction 2.
T6: According to the original size and the reproduction ratio, the scanner
return timing is decided. The timing is corrected to 0 and the charge
corona turns off.
T7: The development bias changes from the image bias to the non-image
bias 444ms (194ms for color) after correction 3.
T8: The separation corona turns off 767ms after correction 3. Then the
development unit drive clutch turns off.
T9: The main motor and non-image development bias turn off 83ms after the
fusing exit sensor detects the trailing edge of the copy paper.
