Measuring the paper length (When the paper is shorter than A4 length of 3802+200msec, the unit moves into 14ppm mode.)
50ms
The temperature reaches T1.
The temperature reaches T2 or T3.
Register is OFF. ~ Starting to pick up the next paper.
When the paper size setting is A4 or Letter, and the paper length is shorter than A4-sized paper, the unit makes prints at 14ppm.
Development (+) OFF ~ Then transfer current fixed 1 is turned ON (OPC and transfer roller cleaning time) Default: Development bias is OFF. SF685: 160 (setting value)*10=1600msec
The warm-up rotation time after reaching T2 (The OPC rotates for 10 seconds when the room temperature is 15
¡C or below.)
Printing start signal
The rise time of development and voltage
The transit time of the paper in an uncharged part
The initial position of paper ~ Register sensor's positioning time
Transfer ~ exposure time
(The register is turned ON. ~ transfer) - (transfer ~ exposure) time + top (compensation value: distortion of the paper) SF686=Default:078 +Offset:900
Top margin
JAM detection
0~350msec
Paper jam is found by detecting the time independently of paper length.
Paper exit operation
The unit starts to pick up the next paper 2msec after the register is turned OFF.
the number of delay stages:
60 stages (473.2ms)
When the fixer reaches the temperature of T2, the warm-up rotation (at a low temperature) will be finished, and also OPC and transfer roller cleaning time will be finished. Satisfying these 2 conditions allows the Solenoid to be turned ON.
Transfer Current Fixed Value 4
(500msec)
(900msec)
The recording paper is exited from the register roller and the motor stops. Then paper jam will be detected before the next paper is picked up. SF683: Offset value 2500+ setting value 057*10=3070msec
Transfer fixed current 4 timing starting point
Transfer control current timing starting point
Note that a gap appears when the timing is off.
Pay attention to the writing of the image because SF667 may cause SF686 to change it.
Bottom control setting after transfer: SF668 (register OFF ~ transfer)-(exposure - transfer) + bottom 5mm + compensation value (distortion of the paper: -30) SF668=(978ms-113ms)+62ms=927ms
