23. IMAGE STABILIZATION CONTROL

23.4 Operation timing

A. Predrive operation
• The following describe the stabilization operations executed when, for example, the main
power/sub power switch is turned ON, the sleep mode is canceled, the front door is
closed, or a malfunction is reset.
Mode
• A new drum unit or a new developing unit is detected.
• A new transfer belt is detected
• The machine recovers from a toner empty condition.
• While a warning code is being displayed.
• In the last image stabilization, the value of IDC regis-
tration sensor detection was out of the specified
Mode 1
range.
(long)
• A change in environment is detected (the threshold
value in changes in absolute humidity
relative to the absolute humidity during the last stabili-
zation sequence).
• The count of the number of printed pages is 10,000
as counted from the last LD adjustment.
• After skew adjustment reset (service mode).
• A Dmax adjustment request is received as a result of
the last gamma correction.
• The count of the number of printed pages after the
gamma adjustment is 400 or more.
• Information is provided indicating that the last stabili-
zation control was discontinued.
Mode 2
• There is a change in temperature after the lapse of a
(short)
predetermined period of time after a developing drive
stop.
• The stabilization is executed when the main power/
sub power switch is turned ON even without the oper-
ating condition (when color priority is selected).
• There is a change of a predetermined value or more
Mode 4
in temperature after the registration adjustment (only
(registration)
when exiting from the sleep mode).
• In the last image stabilization, the value of IDC regis-
tration sensor detection was out of the specified
range.
• A change in environment is detected (the threshold
value in changes in absolute humidity
Mode 5 (mono-
relative to the absolute humidity during the last stabili-
chrome, long)
zation sequence).
• The count of the number of printed pages is 10,000
as counted from the last LD adjustment.
• A predetermined period of time or more elapses after
a developing drive stop.
• A Dmax adjustment request is received as a result of
the last gamma correction.
Mode 6 (mono- • The count of the number of printed pages after the
chrome, short) gamma adjustment is 1000 or more.
• Information is provided indicating that the last stabili-
zation control was discontinued.
