Improving Throughput when Printing Black-and-White Jobs and Full-Color Jobs

When printing intermixed black-and-white and full-color print jobs, switching from full-color mode to black-and-white mode takes time, causing loss of throughput each time the mode is switched.

When the machine prints a full-color print job followed by a black-and-white job, you can improve throughput by adjusting the number of black-and-white sheets the machine prints in full-color mode before switching to black-and-white mode.

1In the [Machine: Image Quality] group on the [Adjustment Settings for Skilled Operators] menu, change the value in [Auto Color Selection Setting].

Specify the appropriate number of sheets for your operating environment.

Value

Machine operation

1 (Minimum)

The machine will switch to the black-and-white mode for all black-and-white printing.

This does not improve throughput, but prevents the cyan, magenta, and yellow development units from working when printing black-and-white sheets.

10 (Maximum)

When the machine prints a full-color print job followed by a black-and-white job, it will switch from full-color to black-and-white mode after printing 10 black-and-white sheets.

Note

  • If you print black-and-white sheets in full-color mode, the cyan, magenta, and yellow development units will work during the black-and-white printing, resulting in a shorter replacement cycle for the photoconductor unit.

  • When the machine prints a black-and-white print job followed by a full-color job, it will always switch to full-color mode, as full-color printing is impossible in black-and-white mode.
