Correction for paper width and thickness (by-pass 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.

SP2-001-1 Charge Roller Bias Adjustment Width 216 - 297 mm (Default: -1630V)
SP2-309-1 Paper Lower Width [a] Width limit (Default: 150 mm)
SP2-309-2 Paper Upper Width [b] Width limit (Default: 216 mm)
