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.

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 recommendations.
