17.1.3 Image stabilization control execution request
• A request for execution of the complete correction control or simplified correction control
is made at the following timing.
*1: Since the machine 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.
17.1.4 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.
