Troubleshooting
Improving the print quality
If you have a print quality problem, make a copy first (put a document on the scanner glass and press Start). 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.
Note
Using
a 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
