Correction For Paper Width And Thickness - Ricoh G179 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 print quality problems.
SP Mode SP Name
SP2001-001 Charge Bias
SP2914-001 C-alpha
SP2914-002 C-beta
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.
