GUIDE ASSY L150 and GUIDE ASSY SD R150
The GUIDE ASSY SD R150 can be adjusted to different paper sizes by moving it to the left or right.
The guides come into contact with the left and right edges of the paper and hold it in position. The
GUIDE ASSY SD L150 moves simultaneously with the GUIDE ASSY SD R150.
LOCK EXTENSION
The 150 Paper Cassette is so constructed that it can cope with the length of the paper in the
direction of travel by moving the position of the HOUSING EXTENSION150 forward and backward.
The LOCK EXTENSION is adopted as a mechanism for holding the HOUSING EXTENSION150 in
position.
GUIDE ASSY END150
This can be adjusted to different paper sizes by making a forward or backward adjustment. This
makes contact with the rear end of the paper, and holds it in position in the forward and rearward
directions.
The paper size to which the cassette is set is transmitted to the LINK SW SIZE 1/2/3 via the GEAR
SECTOR and RACK SIZE by the GUIDE ASSY END150. The three LINK SW SIZE units turns ON
or OFF respectively according to the transmitted paper size. The paper size is detected by
transmitting the ON/OFF information to the Size Switch in the GUIDE TRAY LEFT. The types of
paper that can be automatically detected are as follows:
Legal 14" SEF
Legal 13" SEF
Executive SEF
LEVER BTM LOCK and STOPPER GEAR
These are at the rear end of the cassette (i.e. the exit path of the paper). When the cassette is
inserted into the printer, the protrusions on the Feeder trigger the mechanism that depresses the
LEVER BTM LOCK, slides the RACK BTM LOCK 150, and then simultaneously unlocks the GEAR
PINION and GEAR PB R of the STOPPER GEAR.
PLATE ASSY BTM
The force pushing up the PLATE ASSY BTM is supplied via the SPRING BTM UP150 by unlocking
the LEVER BTM LOCK and STOPPER GEAR. When the PLATE ASSY BTM is pushed up, the
supplied paper and ROLL ASSY NUDGER touch each other.
LOW INDICATOR
The LOW INDICATOR is installed only on the 550 Paper Cassette. The amount of paper remaining
in the cassette is indicated by the LOW IND FRONT. As the amount of paper reduces, the PLATE
ASSY BTM rises and the LOW IND FRONT goes down in the GUIDE INDICATOR.
