Paper Feed Mechanism - Ricoh G190 Service Manual

Paper Feed
When paper with a small width (less than A5) is put in the tray, it does not lift the actuator
[G] of the paper width sensor. Because of this, the paper width sensor detects the paper
that has a width less than A5.
6.3.4 BY-PASS TRAY FEED AND SIZE DETECTION

Paper Feed Mechanism

When the paper detection feeler [A] detects a sheet of paper, the by-pass solenoid [B]
unlocks the feed shaft stopper at the left end of the by-pass feed shaft [C].
The by-pass feed shaft has the feed roller [D] and two cams [E]. These cams move the
paper support plate [F] up and down and pushes the sheets of paper against the feed roller.
Paper Size Detection Mechanism
There is no paper size detection mechanism on the by-pass tray in this printer. Paper size
on the by-pass tray can be adjusted with the operation panel or printer driver.
