● Pre-Registration Control
To correct the feed variation at pickup and to perform the stabilized paper feed, pre-
registration control is executed.
When the paper leading edge is detected at the Pre-Registration Sensor (at Vertical Path
Sensor on cassette 1 only) on each cassette, the machine determines whether to stop the
pre-registration or not.
Pre-registration stop is determined when the following conditions are true.
• There is preceding paper.
• The preceding paper has not reached the Registration Sensor.
• Time until the Registration Sensor of preceding paper is turned OFF > / = time until the
Registration Sensor of succeeding paper is turned ON
● Cassette Heater Control
To prevent paper in the Cassette from absorbing moisture, this machine has a Cassette
Heater at the bottom of the Cassette 2.
This heater is controlled to keep the internal temperature constant.
Whenever the Environment Switch is OFF, the control is always OFF. The behavior
specifications when the Environment Switch is ON are shown below.
When the Main Power Switch is ON
While printing: OFF
While in sleep mode: ON
While in standby: ON*
* ON if the external temperature (COPIER> DISPLAY> ANALOG> TEMP) is lower than 20
deg C, and OFF if the external temperature is higher than 22 deg C.
When the external temperature reaches a temperature between 20 deg C and 22 deg C, it
remains the same as it was immediately before that.
Example 1: When the temperature rises from 15 deg C to 21 deg C The control is ON when
the temperature is 15 deg C, so it remains ON when the temperature rises to 21 deg C.
Example2: When the temperature lowers from 25 deg C to 21 deg C The control is OFF
when the temperature is 25 deg C, so it remains OFF when the temperature lowers to 21 deg
C.
When the Main Power Switch is OFF
Always ON
