When you have finished aligning the outer size change
plate with the marks for the desired paper size, fix the outer
size change plate with the two blue screws using a coin or
something similar, while slightly holding its centre front
portion and pressing it towards you.
Fasten the left blue screw before fastening the right blue screw.
IMPORTANT
If you fasten the blue screw without pressing the outer size change plate
towards you, the plate may be fixed at an angle. If you use the paper deck
with a tilted outer size change plate, paper may be fed as slanted, poor print
quality may result, and paper jams may occur. Therefore, make sure to
fasten the blue screw while pressing the outer size change plate towards
you.

Align the rear edge retainer with the marks for the desired
paper size.
IMPORTANT
If the rear edge retainer is not aligned properly, paper may become
jammed, the quality of the image may be degraded, or the inside of the
main unit may become dirty. Be sure to load paper with the rear edge
retainer properly aligned with the paper size marks on the top and base of
the paper deck.
