10. Improving Throughput
Improving Throughput when Continuously
Performing Black and White and Color Printing
When a combination of black-and-white, full-color and special color printing is performed, switching
color modes takes time, resulting in insufficient throughput.
Optimize the amount of sheets the machine prints in the current color mode before switching to another
mode.
You can switch the color mode as follows:
• From special-color to full-color
• From special-color to black-and-white
• From full-color to black-and-white
Because switching color modes takes time, increasing the amount of sheets before modes are switched
will improve throughput.
1. In the [Machine: Productivity] group on the [Adjustment Settings for Operators] menu,
change the value in 0401: [No. of Sheets for Auto Color Selection].
Optimize the amount of sheets for your operating environment.
Value Behavior
1 (Minimum) • When black-and-white printing is performed after full color printing, full
color mode switches to black-and-white mode after 1 black-and-white
sheet is printed in full color mode. Although throughput is not improved
by this setting, cyan, magenta, and yellow development units are not
used for black-and-white printing.
• When black-and-white printing is performed after special color printing,
special color mode switches to black-and-white mode after 1 black-
and-white sheet is printed in special color mode. Although throughput is
not improved by this setting, special color development unit is not used
for black-and-white printing.
• When full color printing is performed after special color printing, special
color mode switches to full color mode after 1 full color sheet is printed
in special color mode. Although throughput is not improved by this
setting, special color development unit is not used for full color printing.
