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
