Overview

0002-7374

The machine possesses the following 2 modes of operation to suit different printing modes:
a. normal mode (other than mix of different configurations or extra-length)

T-2-3

b. Mix of Different Configurations/Extra-Length

If the originals are of different configurations or are of extra length, the following 3
detection mechanisms are used:

Item

Description

Sensor used 
(notation)

Presence/
absence of 
original

checks the presence/absence of an original in the 
original pickup tray.

original 
placement 
sensor

Original size identification

Feed 
direction

monitors the state of the post-separation sensor (on/
off) after the read sensor goes on to identify the 
original as being small or large.

post-separation 
sensor, read 
sensor

checks the length of the original placed in the 
original pickup tray; identification of LTR and LGL.

LGL sensor

Cross-feed 
direction

checks the width of the original placed in the original 
pickup tray.

original width 
volume (VR1)

identification between A4R/A5R and LTRR/
STMTR
