Here are some possible solutions to print quality problems:
Blurring, Smears, and Streaks - These issues can be caused by a defective toner cartridge or a toner cartridge not installed correctly.
To fix toner streaks, first, print several blank pages to see if it fixes the print quality. Next, try cleaning the internal components of the printer such as the laser scanner/mirrors.
If this doesn't work, re-install the toner cartridge.
