Figure 1-30 1x500-sheet paper feeder circuit diagram Pickup-and-feed operation (PF) The paper feeder uses same mechanism of the product for the pickup-and-feed operation. The rollers used in the paper feeder are driven by the feed motor (M101) of the product through the gears. Pickup and feed sequence of operation (PF) 1. The lifting plate moves up to the position where the paper can be picked up after the product is turned on or the paper feeder cassette is installed. 2. The DC controller drives the feed motor (M101) when it receives a print command from the for- matter. 3. The DC controller outputs a pickup command to the paper feeder driver. 4.
The paper feeder driver turns on the PF pickup solenoid (SL1600) when it receives a pickup command.
Accordingly the PF pickup roller, PF feed roller and PF feed roller 1 rotate to pick up ENWW 1x500-sheet paper feeder 41 Paper feeder +3.3V +24V M Motor +3.3V generation circuit Solenoid +24V DC controller Switch Sensor Paper feeder driver Paper feeder/Paper deck Paper feeder +3.3V +24V M Motor +3.3V generation circuit Solenoid Switch Sensor Paper feeder driver +3.3V +24V +3.3V generation circuit Paper feeder driver Paper feeder/Paper deck +3 gene cir .3V ration cuit Component Description Motor M1600 Paper feeder lift motor Sensor PS1600 Paper feeder media presence sensor PS1601 Paper feeder media stack surface sensor 1 PS1602 Paper feeder media stack surface sensor 2 PS1603 Paper feeder media path sensor Solenoid SL1600 Paper feeder pickup solenoid Switch SW1600 Paper feeder media size switch
