Checklist Before Troubleshooting Print-Quality

Check Printer Condition

Consumable and Long Life Maintenance Items
Check the consumable counters to determine the amount of life remaining in each Toner Cartridge,
Imaging Unit, and Fuser Unit. Replace any consumable or maintenance item that is at of near end of
life before troubleshooting print defects.
Low toner can cause problems, such as fading, streaking, White lines, or dropouts. Imaging Units
approaching end of life may produce high frequency banding and affect the printer's ability to
maintain toner density increasing calibration cycles.

Cleaning

Paper, ink debris, and dust particles can accumulate inside the printer and cause print-quality problem
such as Smearing. Clean the inside of the printer to prevent these problems.

Operating Environment

Check the temperature, humidity, clearances, and supporting surface meet specifications. Refer to
Environmental Specifications on page 1-33.

Media Condition

Paper should be fresh and stored in the operating environment for 12 hours before use for printing. The
print-quality is best when quality paper is fed from the tray. The print quality is evaluated on the
maximum size of each centerline media. Check the condition and type of media loaded. Refer to Media
Guidelines on page A-2 for details on determining proper media condition.
