6.3.2 MECHANISMS
Paper Size Detection
The machine detects paper size based on the setting that the operator chooses on
the paper size dial [A]. The paper sizes are detected by the paper size detection
switches [B] through their contact with small projections on the paper size dial.
It is therefore necessary to adjust the setting on the dial when a different sized
paper is used. If this is not done, images meant for paper sizes larger than the size
selected on the dial will be partially cut off.
In addition to paper size detection, this dial setting also provides the basis for jam
detection timing. The sensor also detects whether the tray has been inserted or not.
