Problem Cause Solution
The USB cable might be defective or
incorrectly connected.
●
Disconnect the USB cable at both
ends and reconnect it.
●
Try printing a job that has printed in
the past.
●
Try using a dierent USB cable.
Other devices are running on the host
computer.
The printer might not share a USB port. If
an external hard drive or network
switchbox is connected to the same port as
the printer, the other device might be
interfering with the printer. To connect and
use the printer, disconnect the other
device or use two USB ports on the host
computer.
The print job might not have arrived at the
printer.
Check the printer status queue. Also, the
Printing message should appear on the
control panel display.
Print speeds
Print speed is the number of pages that print in one minute. Print speed depends on dierent engine-process
speeds or operational pauses between printed pages during normal printer operation. Factors that determine
the print speed of the printer include the following:
●
Page formatting time
The printer must pause for each page to be formatted before it prints. Complex pages take more time to
format, resulting in reduced print speed. However, most jobs print at full engine speed.
●
Media size
Legal-size media reduces print speed because it is longer than the standard Letter- or A4–size media. A
reduce print speed is used when printing on narrow media to prevent the edges of the fuser from
overheating.
●
Media mode
Some media types require a reduced print speed to achieve maximum print quality on that media. For
example, glossy, heavy, and specialty media (for example, envelopes or photos) require a reduced print
speed. To maximize the print speed for special media types, make sure that the correct media type in
the print driver is selected.
●
Printer temperature
To prevent printer damage, print speed is reduced if the printer reaches a specic internal temperature
(thermal slow down). The starting temperature of the printer, ambient environment temperature, and
the print job size eect the number of pages that can be printed before the printer reduces the print
speed. Thermal slow down reduces print speed by printing four pages and then pausing for an amount
of time before printing continues.
●
Other print speed reduction factors
Other factors (especially during large print jobs) that can cause reduced print speeds include:
