Switching from the color mode to the black-and-white mode

A. OUTLINE
• If more than 5 black-and-white sheets are fed consecutively from the DF in which both the color sheets and
the black-and-white sheets are stored, the pressure on the first transfer rollers /Y/M/C are released and it
shifts to the black-and-white mode.
• At this time, the switch is performed during the job, so there is a time lag between the color print and the
black-and-white print.
B. Switching sequence from the color mode to the black-and-white mode
1.
The second transfer for the previous print sheet (color) is complete.
2.
A pressure is applied only to the first transfer roller /K (the first transfer rollers /Y/M/C are in release state).
3.
Writing/K is started.
4.
The operation of the drum unit /Y/M/C, the developing unit /Y/M/C, and the toner supply unit /Y/M/C are
canceled.
C. Switching sequence from the black-and-white mode to the color mode
1.
A color print job is detected.
2.
The second transfer for the previous print sheet (black-and-white) is complete.
3. The operation of the drum unit /Y/M/C, the developing unit /Y/M/C, and the toner supply unit /Y/M/C are
started.
4.
MPC or APC is executed for the write unit /Y/M/C.
5.
A pressure is applied to the first transfer roller /Y/M/C/K.
6.
Writing /Y is started.

Count when using ACS

• There are two kinds of print count when using ACS.
A. The black-and-white mode (the first transfer roller /Y/M/C is in the release state)
Total count
Developer counter
B. The color mode (the first transfer roller /Y/M/C/K is in the pressure state)
Total count
Developer counter
*1 When the original is black-and-white, the output will be black-and-white; however, the developer counter
counts it as color print and the total counter counts it as black-and-white print.
