Auto Quality Start Mode
Auto Quality Start is done if the user does not select Quality Start mode. (Auto
Quality Start can be disabled with a user tool: System Settings – Mode Setting –
Auto Quality Start Setting).
In Auto Quality Start mode, the idling motion depends on how long the machine
was not in use and on the temperature detected by the thermistor [A] in the drum.
The CPU detects a low temperature condition if the thermistor [A] reports
approximately 19
°
C or lower. If the detected temperature is 29
°
C or higher, it is a
high temperature condition.
The number of drum idling rotations depends on temperature and period of
machine inactivity, as shown in the following table.
A user tool can change the number of rotations for each of these conditions
(System Settings – Mode Setting – No of Idling Rotations: Auto Quality Start).
