8.6.1 500-Sheet Paper Feeder
8.6.1.1 Function
•
500-Sheet Paper Tray:
This Tray can accommodate up to 500 cut sheets of plain paper.
The Tray is provided with a Paper Guide at the rear part on its right side. When the Paper
Guide is set to a desired paper size, the straps of the Actuator on the left side of the Tray are
expanded or compressed. The middle part of each strap thereby projects or retracts, forming
the pattern of projections (number and position) which corresponds to the paper size. The
projections press the Size Spring on the Feeder PWB against the Paper Size Switches.
The Tray is provided with a slot for allowing paper from the lower (bottom) Feeder to pass
through into the printer between the handle portion at the front and the body portion which
accommodates paper.
•
500 Paper Size PWB Assembly:
Three Paper Size Switches, Tray Latch Spring and Tray Actuator Spring are mounted on this
printed wiring board.
•
Paper Size Switches:
These switches are directly mounted on the PWB. They are “On” when being pressed by the
Size Spring. The Tray (loaded or unloaded) and the size of paper are detected by the combi-
nation of On and Off switches.
•
Tray Actuator Spring:
The Tray Actuator Spring presses the Size Spring against the Paper Size Switches with the
pattern of projections corresponding to the paper size.
•
Tray Latch Spring:
This Latch is a spring which secures the 500-Sheet Tray in place.
