6.8.3 CORRECTION FOR PAPER WIDTH AND THICKNESS
NOTE: This correction is done for the bypass tray only.
The by-pass tray can be used for non-standard paper narrower than sizes
accepted by the paper trays. Thicker paper, OHP sheets, etc. can also be loaded in
the by-pass tray but adjustments must be performed with the SP modes listed
below in order to avoid jams and copy quality problems.
