15.4 Operation timing

15.4.1 Predrive operation

• The following describe the stabilization operations executed when, for example, the main power switch is turned ON, the sleep mode is
canceled, the front door is closed, or a malfunction is reset.
Mode
• A new imaging unit is detected.
• An alternative imaging unit is detected.
• A change in environment is detected (there is a change in humidity or temperature of a predetermined value or more from the
last image stabilization sequence).
Mode 1 • There is a change in environment (temperature) inside the PH of a predetermined value or more during a multi-print cycle.
• A trouble has been reset.
• Performance of a simplified correction control sequence is not effective.
• During the sleep mode, a change in environment is detected (there is a change in humidity or temperature of a predetermined
value or more from the last image stabilization sequence). *
• When the main power switch is turned ON, a period of time of 24 hours or longer elapses after the last event of turning power
OFF.
Mode 2
• The number of printed pages produced reaches a predetermined value after the last image stabilization sequence.
• The machine is reset from the sleep state that has extended for a predetermined period of time or longer.
• There is a change in environment (temperature) inside the PH of a predetermined value or more.
Mode 3
• There is a change in environment (temperature) inside the PH of a predetermined value or more during the sleep mode.
• A 1200-dpi print command is received.
Mode 4
• A panel menu is executed.
• With "Black priority" set in image stabilization settings of the service mode, the number of printed pages produced reaches a

predetermined value or there is a change in environment (temperature) inside the PH of a predetermined value or more.
• *: An environmental check is made every hour during the sleep mode and the power supply cooling fan is driven for several sec. to take
measurement.
(1) Stabilization mode setting
• To change the type and timing of image stabilization.
• Use this function to perform the image stabilization control that suits a specific style of use according to the rate of use of color and black
of the user.

15.4.2 During a print cycle

• When the stabilization execution condition is met during printing, a specific image stabilization mode according to the condition is selected
and executed.
A change in environment is detected (there is a change in humidity or temperature of a
predetermined value or more from the last image stabilization sequence).
The number of printed pages produced reaches a predetermined value after the last image
stabilization sequence.
There is a change in environment (temperature) inside the PH of a predetermined value or more.
With "Black priority" set, the number of printed pages produced reaches a predetermined value
after the last image stabilization sequence.

15.4.3 Service Mode

• Types (modes) of image stabilization to be executed with the menu of the SERVICE MODE will be described.

during predrive.
• Black stabilization is executed if image adjustments are necessary for black print during
predrive.
• Color stabilization is executed before color print if image adjustments are necessary for color
print.
