3. Measure the pitch of the bands.
Solution
1. Set the process speed to "3: Low speed" and decrease the fusing heat roller temperature 10
°C from the current temperature in IMSS (or in SP mode).

2. Print the test pattern and check the results. If the fuseability has degraded, turn on the "Toner
reduction" mode provided that the image is of 3C and image quality is maintained.
3. Again, print the test pattern and check the results. If the fuseability is still poor, increase the
heating roller temperature 5°C. (DO NOT set the temp higher than 180°C.)
4. If the problem does not resolve, replace the PCB (K/C) and/or PCB (M/Y) depending on the
color showing the problem.
