PCU Reverse Interval [0 ~ 999 / 100 / 1 sheet/step]
0: Never cleans during job
2211*
Adjusts the PCU reverse interval for cleaning during a job.
When the machine has made this number of copies in the middle of a job, the
machine reverses to clean the edge of the cleaning blade. After cleaning, the
machine resumes the job. Set to a shorter interval if thin white lines appear on
printouts.
Copies after Near End [ 0 = 50 pages / 1 = 20 pages] 2213*
Selects the number of copies that can be made after toner near-end has been
detected.
If the user normally makes copies with a high proportion of black, reduce the
interval.
2220* Vt/Vsg/Vsp/Vsdp/Vts Display
2220 1 Vsp
2220 2 Vsg
2220 3 Vsdp
2220 4 Vt
2220 5 Vts Displays the individual Vt, Vsg, Vsp, Vsdp, and Vts
values.
2220 6 Vsp/Vsg/Vsdp/Vt/Vts Displays all the data used in process control, separated
by slashes (/).
2301* Transfer Current Adjust
2301 1* Normal Paper
Adjusts the current applied to the transfer roller during copying from a paper tray
when the user uses the “Normal” paper setting.
If the user normally feeds thicker paper from a paper tray, use a higher setting.

2301 2* Thick/Thin Paper
Adjusts the current applied to the transfer roller during copying from the by-pass
tray. These settings are also used if the 2nd tray is used and special paper is
selected.
If the user normally feeds thicker paper from the by-pass tray/2nd tray (special
paper), use a higher setting. If waste toner is re-attracted from the drum (this can
occur when using an OHP sheet), use a higher setting.
[0 = –2 µ A / 1 = 0 µ A / 2 = +2 µ A / 3 = +4 µ A]
2301 3* Duplex, Side2
Adjusts the current applied to the transfer roller during copying from the duplex
unit when the user uses the “Normal” paper setting.
Use this SP when the image on the rear side of the paper has a problem caused
by poor image transfer.
[0 = –2 µ A / 1 = 0 µ A / 2 = +2 µ A / 3 = +4 µ A]
2301 4* Cleaning
Adjusts the current applied to the transfer roller during roller cleaning.
If toner remains on the roller after cleaning (dirty background appears on the rear
side of the paper), increase the current.
