Switching The Deck Paper Size; Detecting The Level Of Paper In The Deck - Canon CLC 1120 Service Manual

CHAPTER 10 PAPER DECK

2. Switching the Deck Paper Size

The deck copy paper size may be changed by moving the guide plate inside the deck and then
entering the new paper size in service mode (OPTION>ACC>DK-P) at time of installation or at the
request of the user.

3. Detecting the Level of Paper in the Deck

The deck is capable of finding out an approximate volume of copy paper inside its
compartment using the deck paper level upper sensor (PS107), deck paper level lower sensor
(PS108), and deck paper absent sensor (PS102). It sends the result of its finding to the copier,
which in turn will indicate the level on its control panel.
Table 10-101 shows the relationship between the level of copy paper and the states of sensors
and the indications on the control panel.
