AUTO SPEED
MONO 32PPM
COLOR SPEED
MIXED SPEED
If the first page of a print job is black
and white, the MFP runs at 32ppm
(pages per minute). When a color page
is detected the MFP slows down to
20ppm for the rest of that job.
This setting operates in the same way
as AUTO SPEED, except that the MFP
runs at 32ppm until a color page is
detected. To achieve this speed the MFP
requires an additional 10 – 20 seconds
to warm up and 30 –60 seconds to cool
down when switching to 20ppm for
color pages. This setting is therefore
most appropriate when the majority of
print jobs are entirely black and white.
The MFP runs at 20ppm for all print
jobs. This setting is most appropriate
when the majority of print jobs are in
color.
The MFP automatically switches
between 20ppm for each color page and
32ppm for each black and white page.
When black and white pages are
printed, the 3 color drums are
automatically lifted to maximize their
working life. This operation imposes
delay each time the MFP switches
between color and black and white
printing. However, the 30 –60 second
cool down delay described for MONO
32ppm is avoided by limiting mono
speed to 20ppm. This setting may be
preferred for mostly black and white
printing with some color pages, or
where most print jobs are entirely color
or entirely black and white.
