CEZ604 Cause: One of the charge rollers is stained. Solution: To identify the affected color, print three full-page, solid-fill A3 or DLT sheets for each of white and black, and three full-page, halftone A3 or DLT sheets for each of cyan, magenta, and yellow.

    Bands Bands Banding: General Density fluctuation occurs periodically in the vertical direction to the paper feed direction. CWH407 Cause: Density fluctuation occurs when the pitch phase between the charge roller, developing roller, paper transfer roller, and photoreceptor is different. Solution: The solution depends on the length of intervals whereby the density fluctuation occurs.
  • Page 50 5. Image Quality Problem: Lines Go to the next step. Print a full-page, half-tone A3 sheet for each of cyan, magenta, yellow, and black, and then measure by a ruler, etc., the intervals between the spots affected by density fluctuation. Perform the following solution.
