  • Code: 100.03...100.99
  • Description: ITU Error
  • Remedy: Replace the ITU assembly
  • Code: 106...109
  • Description: 106.xx Printhead Error Cyan printhead error. 107.xx Printhead Error Magenta printhead error 108.xx Printhead Error Yellow printhead error 109.xx Printhead Error Black printhead error
  • Remedy: If you get a printhead error, follow this diagnostic to find the specific failure. 1. Remove the top cover. See “Top cover assembly removal”. 2. Remove the outer system board shield. See “Outer system board shield removal”. 3. Verify that all the connectors are properly seated. Check the printhead cable connectors on the printheads as well as the printhead cable connectors and mirror motor cable connectors on the system board. If the printhead and mirror motor cables are properly seated and the error remains, record the error code. Continue to the next step. 4. Select which pair of printheads to switch based on the error code. • If the printer displays one of the codes that indicate yellow or cyan, switch the yellow with the cyan printhead cable and the yellow with the cyan mirror motor cable. • If the error code indicates a magenta or a black error, switch the magenta with the black printhead cable and the magenta with the black mirror motor cable. 5. Turn on the printer and compare the new error codes with the original error code you recorded. Note: If an automatic calibration begins, 36 Printer Service Required may appear. Check the printhead cable connections. Press to clear the error. • If the error code remains the same, replace the system board. See “System board removal”. If that solves the problem, you are finished. Make sure you return all the cables to the original positions. • If the printer displays a different printhead error code, which indicates the code for the other color of the pair you switched, the printhead or the printhead cables are defective. Return all the cables to the original positions. Replace the printhead cables. If the problem remains, replace the printhead. See “Printhead removal and adjustments”.
