Improving the print quality C
If you have a print quality problem, print a test page first (Menu, 4, 2, 3). If the printout looks good,
the problem is probably not the machine. Check the interface cable connections or try printing a
different document. If the printout or test page printed from the machine has a quality problem,
check the following steps first. And then, if you still have a print quality problem, check the chart
below and follow the recommendation.
a Check that you use the paper that meets our specifications. (See Acceptable paper and other
print media on page 18.)
To get the best print quality, we suggest using the recommended paper. (See Acceptable
paper and other print media on page 18.)
b Check that the drum units and toner cartridges are installed correctly.

Difficulties Suggestions
The machine will not turn on. Adverse conditions on the power connection (such as lightning or a power surge)
may have triggered the machine’s internal safety mechanisms. Turn the machine
off and unplug the power cord. Wait for ten minutes, then plug in the power cord
and turn the machine on.
If the problem is not solved, turn off the machine. Plug the power cord into a
different known working outlet and turn on the machine.
