Figure 4-9. Unseated or Defective Trailing Cable.
13. Replace both trailing cables for vertical white gaps or spaces in
the Prime pattern, jumps in color, or for irregular patterns with
horizontal lines. Also refer to Microbanding. Refer to
Disassembly for trailing cable replacement procedures.
14. Replace the carriage PWA for single or multiple color firing
related problems. Note: The carriage PWA is responsible for
printing all test patterns, calibrations, and prime patterns; i.e., a
defective carriage PWA with a defective cyan driver will cause all
printed cyan patterns to be incorrect. Only replace if this is the
case. Refer to Disassembly.
Figure 4-10. Defective Carriage PWA.
If the color test appears like this example and other printing is
faulty then the carriage PWA is defective.
