Image Quality Problems

Various situations can affect the quality of the output. Check the following conditions to ensure optimum copy and print performance.

If you still cannot resolve the problem, contact the Key Operator or a local service representative.

-Do not locate the WorkCentre Pro 421 in direct sunlight or near a radiator.

-Avoid sudden temperature and humidity changes in the WorkCentre Pro 421’s environment. When a change occurs, allow the WorkCentre Pro 421 at least two hours to adjust its settings to the new environment, depending on the severity of the change.

-Follow regular maintenance schedules for cleaning areas, such as the Document Glass, CVT and output trays. Refer to “Cleaning the WorkCentre Pro 421” on Page 5-2.

-If the copy quality is poor with uneven, faint, degraded print or a white line is visible in the direction of the paper feed, clean the Transfer Corotron Wire. Refer to “Transfer Corotron Wire” on Page 5-4.
