Troubleshooting Solving Image-Quality Problems Problem See: 3 Banding in yellow, red and _ green columns only, but more evident in yellow than in red and green columns. This is an indication that the yellow printhead may require servicing or could be damaged. 4 Banding in black column _ only. This is an indication that the black printhead may require servicing or could be damaged. Corrective Action Refer to 11-16, Nozzle Print Test for the yellow color. Verify this problem and see the recommended actions Refer to test 11-16, Nozzle Print Test for the black color. Verify this problem and see the recommended actions. Banding Caused by Media Advance Problems Another type of banding is caused by an inaccurate media advance. The printer prints an image in 'bands' or 'swaths' which have fixed widths depending on the advance of the media roller. If the advance of the roller differs from the theoretical advance, there will be banding (horizontal repetitive bands along the test pattern) in all the primary and secondary color columns. The bands can appear as dark bands, due to a shorter advance of the roller which causes an overlap, or lighter bands due to a longer advance causing spaces. 11-13
