Improving the print quality

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 17.)

Note

To get the best print quality, we suggest using the recommended paper. (See Acceptable paper and other print media on page 17.)

b Check that the drum units and toner cartridges are installed correctly.
