Improving The Print Quality - Brother FAX-2840 Basic User's Manual

Improving the print quality

If the printout has a quality problem, make a copy. If the copy looks good, the problem is probably
not the machine. Check the interface cable connections and the following steps first. And then, if
you still have a print quality problem, check the chart below and follow the recommendations.
Note
Brother does not recommend the use of cartridges other than genuine Brother Original
cartridges or the refilling of used cartridges with toner from other sources.

To get the best print quality, we suggest using the recommended paper. Check that you use
paper that meets our specifications. (See Acceptable paper and other print media
uu page 19.)
