4.2 Cassette Feed
When the fixing rollers reach the specified temperature while a cassette with paper is in the
printer, the READY lamp changes from flashing to lighting.
When the engine controller circuit receives PRNT or PRFD signal from the video controller
circuit, the paper feed motor starts rotation. About 0.2 seconds later, the printer actuates the
tray1 pick-up roller solenoid and the pick-up roller makes one rotation. This feeds paper to the
photosensitive drum.
