Item Description
Method of stacking Sorting by shifting trays
face up/ face down stacking
Mode of stacking non-sort, sort (stack shift)
Source of drive ascent/descent: by coil spring (descent by paper weight)
shift movement: by motor
Size of paper for stack*1 non-sort: A3, A4, A4R, A5R, B4, B5, B5R, 11x17, LGL, LTR,
LTR-R, STMT-Rsort: A3,A4, B4, B5, 11x17, LGL, LTR
Paper type plain paper (64 to 90g/m2), recycled paper (64 to 80g/m2), eco
paper, tracing paper, transparency, colored paper, postcard,
double-postcard, 4-plane postcard, label paper, thick paper (91
to 200g/m2)
Weight of Paper for stack 64g/m2 to 200g/m2
Movement of offset in units of sets
Maximum number of sets in stack sort:500sheets(64g/m2 paper)
non-sort:250sheets(64g/m2 paper)
Accuracy of alignment sort:50mm or less(delivery direction)
20mm or more(shift direction,between stacks)
between stacks-5mm or less(shift direction,within stack)
non-sort:100mm or less
Tray full detection*2 by reection type sensor (2 pc.) monitoring height of stack
Power supply DC24V/DC5V(from host machine)
Maximum power consumption 12W or less
Dimensions 365.3mm(W)x547mm(D)x255.7mm(H)
Weight 4.2kg
Operation environment same as host machine
*1: tranceparencies, postcards and label papers may not be sorted.
*2: the machine stops printing when the stack exceeds a specic height.

Outline of the Electrical Circuitry
The circuit shown below is used to drive the shift motor according to the shift control signal
from the host machine and also to send various sensor signals associated with the shift
operation to the host machine.

Basic Operation
Shift Movement
The machine moves the tray to the front and the rear to sort stacks (offset). The tray is
driven by a DC motor, and the rotation of the motor is converted into liner movement
by means of a rack and pinion gear mechanism. The location of the tray (front, rear) is
monitored by the HP sensor mounted to the front and the rear.

Placement of Paper
The machine's tray is held up by the work of a coil spring. When paper is placed, the tray
moves down under the weight of the paper. The height of the stack in the tray is monitored
by the tray full sensor (reection type photo sensor), and the shift tray driver PCB sends the
tray full signal to the host machine when the top of the stack reaches a specic height.

Detecting the Presence/Absence of Paper
The presence/absence of paper in the tray is detected by the paper sensor mounted to the
tray.

Delivery Movement
The paper from the host machine is delivered to the tray through the shift drive unit, which
is driven by the host machine's gear mechanism.
