Paper Feed Transport Mechanism
In this machine, to maintain the paper gap constant, switching the paper feed roller ON/OFF adjusts the paper feed timing.
1. The paper feed motor is switched ON, and the first sheet is supplied.
2. Just before the rear edge of the first sheet leaves the paper feed roller, the paper feed motor switches OFF.
3. When the first sheet is fed a predetermined distance by the downstream transport roller, the paper feed motor switches ON to supply the second sheet of paper.
Paper Size Detection (1st Paper Supply Tray)
Size cannot be detected only with set detection.
1st tray settings:
A4 LEF, LT LEF, B5 LEF, and A5 LEF (select with UP mode, default is A4 LEF)
Paper Size Detection (2nd Paper Supply Tray)
The end fence interlocking rotation detection plate is an automatic detection system which recognizes patterns by a 4-position push switch.
Size is detected by the detection patterns of knobs 1, 2, 3, and 4. Tray set is detected by another switch.
If there has been a change in the pattern, "MFP tray automatic size detection" control is performed continuously.
If the paper size is selected manually by user setting, the automatic size detection is overridden.
