Canon NP6218 Service Manual page 140

To change the cassette size, you must not only move the guide plate (horizontal,
vertical) inside the cassette to suit the copy paper but also move the paper size lever
located toward the front of the cassette (Figure 5-501) to the left or right so that the arrow
points to the appropriate paper size.
Caution:
A discrepancy between the size set by the paper size lever and the size of copy
paper will result in jams or soiling because of the wrong copying sequence.
Advise the user to be sure to match the size set by the paper size lever and the size
of copy paper.
Reference:
Paper size configurations differ from area to area; however, you may still make sure
of a specific copy control sequence for the size of paper that does not fall under the
respective category—the size, nevertheless, will not be indicated on the display.
For instance, you may use LTR paper for a metric model. (The paper size lever, in
this case, will be set to LTR.) This arrangement causes the copier to execute the
copying sequence intended for LTR copies.
