4.3 Items to Be Confirmed Before Image Quality Troubleshooting

Print Quality Problems
Customers may need your help determining the cause of print quality issues such as streaking, fading,
or dropouts. Here are some questions that may help you determine why your customer's printer is not
printing optionally. First, confirm the following items to understand customer's operating condition.
1) Does your customer's print media fall within the Printer Media Guidelines? (Refer to "Printer Media
Guidelines").
2) Is there enough toner?
3) Has the printer been cleaned recently?
Checking printer condition
Toner
Low toner can cause print quality problems such as fading, streaking, white lines, or dropouts. Have
your customer print a small document from a different application to replicate the problem and verify
the amount of toner available for printing. When your customers print a document, the Laser Printer
Status Monitor should display a dialog box that estimates the amount of toner left in the cartridge.
If the toner is low, your customers can sometimes extend the cartridge life by removing the cartridge
from the printer, gently shaking it from side-to-side, and replacing it (Rocking the toner cartridge from
side-to-side loosens toner that may get stuck).
Cleaning
Paper, toner, and dust particles can accumulate inside the printer and cause print quality problems,
such as smearing or toner specks. Clean inside the printer to prevent these problems.
