Print-Quality Troubleshooting
Checklist Before Troubleshooting Print-Quality
Check Printer Condition
Toner
Low toner can cause print-quality problems, such as fading, streaking, White lines,
or dropouts. Print a small document from different software applications to
replicate the problem and check the amount of toner available. If the toner is low,
replace the affected cartridges.
Cleaning
Paper, toner, and dust particles can accumulate inside the printer and cause print-
quality problems such as smearing or specks. Clean the inside of the printer to
reduce these problems. Refer to “Cleaning” on page 7-2.

troubleshooting. These actions may help resolve the problem without
troubleshooting the printer.
