By-pass: Image Area
005
Adjusts the transfer current for copying from the by-pass tray.
If the user normally feeds thicker paper from the bypass tray, use a higher
setting.
By-pass: Leading Edge
Adjusts the transfer current for copying at the leading edge of paper fed
006
from the by-pass tray.
Increase the current to separate the paper from the drum properly in high
humidity and high temperature conditions.
No Image Area (SSP)
008
Adjusts the transfer current for copying.
2309* Current: Paper Size Correction (SSP)
Paper Lower Width (a)
Adjusts the lower paper width threshold for the transfer current, charge
voltage, and development bias corrections.
001
Use this SP when an image problem (e.g., insufficient toner transfer) occurs
with a small width paper. If the paper width is smaller than this value, the
transfer current will be multiplied by the factor in SP2-309-3 (paper tray) or
SP2-309-5 (by-pass).
Paper Upper Width (a)
Adjusts the upper paper width threshold for the transfer current, charge
002
voltage, and development bias corrections.
As for SP2-309-1, but the factors are in SP2-309-4 (paper tray) and
SP2-309-6 (by-pass).
