d. Turn on the printer and note the new error codes.
• If an automatic calibration begins, 36 Printer Service Required may appear. The printhead and
system board are working correctly and the printhead cable connections should be checked.
Press Go to clear the error.
• If the error code remains the same, replace the “System board”. If that solves the problem, you
are finished.
• If the printer displays a different printhead error code, which indicates another color, the
printhead or the printhead cables are defective. See the following table for the printhead codes.
For example, the printer originally displays the printhead error code 108 (yellow). After switching the
signals using the diagnostic tool, the printer displays the printhead error code 106 (cyan).
4. Remove the printhead diagnostic tool.
5. The problem is in either the printhead cables or the printhead. Replace the printhead cables. If the problem
persists, replace the printhead. See “Printhead removal and adjustments” on page 4-60.
Note: Replace and adjust only one printhead at a time.
