Image stabilization control execution request

• A request for execution of the complete correction control, simplified correction control,
or individual registration control is made at the following timing.
Stabilization request timing
When a new IU is detected
When a other used IU is
Upon
detected
replace-
ment of unit
When the transfer belt unit is
replaced
When the power switch is
turned ON
When there is a great change
in environmental conditions
from those when the last sta-
bilization sequence was exe-
cuted.
By main
body status
When there is a temperature
change inside the PH unit
At the end of a print cycle of
given conditions
When a malfunction is reset
Special
When all trays get empty
situation
User When engine/engine service/
selection calibration is selected
*1: Since the main body is not provided with a function that detects a new transfer belt unit,
engine/engine service/calibration must be selected and complete correction control
executed whenever the unit has been replaced with a new one.
*2: See the following for the conditions that enable execution of the stabilization control at
the end of a print cycle of given conditions.
21.1.5 Conditions enabling execution of stabilization control at the end of a print
cycle of given conditions
• The time equivalent to the number of printed pages produced by each TC is counted
after the execution of the last image stabilization sequence.
• The equivalent time counter of all TCs is reset after the execution of the image stabiliza-
tion sequence.
A. Calculation of equivalent printed page time
• The period of time through which the developing unit is driven is used for the equivalent
printed page time.
• Half of the developing unit driving time involved with 2P/J is one printed page time.
