Correction For Paper Width And Thickness - Ricoh D009 Service Manual

Drum Charge

Correction for Paper Width and Thickness

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.
SP Mode SP Name

Adjustment
SP2309-001 Paper Lower Width [a]
SP2309-002 Paper Upper Width [b]

The way that these SP modes are used is shown below.
For example, with the default settings, if the paper width fed from the by-pass tray is 200 mm,
the charge roller voltage will be –1500 +0 V.
