The print job is extremely slow.
Cause Solution
The job might be very complex (if it contains graphics, for
example). ● Wait for the job to print.
● Reduce the complexity of the page or try adjusting the
print-quality settings. If this problem occurs frequently,
add memory to the printer.
The maximum printer speed is 19 ppm in black for A4-size
paper, 20 ppm in black for letter-size paper, and 4 ppm in
color (for A4 or letter). This speed cannot be exceeded even
when more memory is added. Wait for the print job to finish.
Printing speeds might be automatically reduced when
printing on special-sized media. Wait for the print job to finish.
In the printer driver, the Type or Size is set for card stock or
other special media. ● If you are printing on special media, the Type or Size
should be set to match the media. The printer prints
more slowly for some media types to provide better
quality. Wait for the job to print.
● If you are not printing on special media, set Type or
Size in the printer driver to plain paper.
● In the default settings for this printer, click the Paper tab
and ensure that Type is set to plain paper. You can
override this setting from the printer driver when you
print on special media.
An issue might exist with the driver. If you were printing by using the PCL driver, print by using
the PS driver, or vice versa.
The printer might be hot. If the printer has been printing for a long time and is hot, it
automatically slows its printing speed to prevent print-quality
defects. To restore the printer to full speed, stop printing and
wait for the printer to cool.
