Function
*
Adjusts the TD sensor reference voltage
(V
).
REF
Change this value after replacing the
development unit with another one that
already contains toner.
For example, when using a development
unit from another machine for test
purposes, do the following:
1. Check the value of SP2-220 in both the
machine containing the test unit and the
machine that you are going to move it to.
2. Install the test development unit, then
input the V
for this unit into SP2-220.
REF
3. After the test, put back the old
development unit, and change SP2-220
back to the original value.
*
Displays the current TD sensor output
voltage.
*
Adjusts the current applied to the transfer
belt during copying on the 1st side of the
paper.
If the user uses thicker paper, the current
may have to be increased to ensure
sufficient transfer of toner.
*
Adjusts the current applied to the transfer
belt during copying on the 2nd side of the
paper.
See above.
*
Adjusts the current applied to the transfer
belt during copying from the by-pass feed
table.
See above. If the user normally feeds
thicker paper from the bypass tray, use a
higher setting.
*
Adjusts the current applied to the transfer
belt during copying on post cards from the
by-pass feed table.
The post card mode is selected when the
by-pass tray is selected and the width is
detected as A6.
*
Adjusts the current applied to the transfer
belt between the pages.
