C alpha [0 ~ 400 / 150 / 10V step]
Adjusts the charge roller voltage used when paper with a small width is fed from the by-pass
tray. The paper width below which the correction starts depends on the value of SP2-309-1.
Use this SP when an image problem (such as white spots at the center of black dots or breaks
in thin black lines) occurs when paper with a small width is fed from the by-pass feed tray.
002
C beta [0 ~ 400 / 0 / 10V step]
Adjusts the charge roller voltage used when paper with a small width is fed from the by-pass
tray. The paper width below which the correction starts depends on the value of SP2-309-2.
Use this SP when an image problem (see 2-914-1) occurs when paper with a small width is fed
from the by-pass feed tray.
003
B gamma [0 ~ 300 / 200 / 10V step]
Adjusts the development bias used when paper with a small width is fed from the by-pass tray.
The paper width below which the correction starts depends on the value of SP2-309-1.
Use this SP when an image problem (see 2-914-1) occurs when paper with a small width is fed
from the by-pass feed tray.
004
B delta [0 ~ 300 / 50 / 10V step]
Adjusts the development bias used when paper with a small width is fed from the by-pass tray.
The paper width below which the correction starts depends on the value of SP2-309-2.
Use this SP when an image problem (see 2-914-1) occurs when paper with a small width is fed
from the by-pass feed tray.
