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.) Note To get the best print quality, we suggest using the recommended paper. (See Recommended paper and print media on page 18.) b Check that the drum units and toner cartridges are installed properly.

Make sure that you choose the proper media type in the printer driver or in the machine's Paper Type menu setting. (See Acceptable paper and other print media on page 18 and Basic tab in the Software User's Guide on the CD-ROM.) Shake all four toner cartridges gently.
