6. Ensure that the umbilicals are seated correctly, Figure 6.
Figure 6 Umbilical seating
7. Firmly tighten the screws on the umbilical clamp, failure to do so can result in ink leaks.
8. Ensure that both carriages are parked and the wiper is in the home position, all the way
up or down.
9. Ensure the harnesses are routed correctly, refer to GP 28.
CAUTION
Failure to properly prime the new umbilical will lead to permanent damage to the ink reservoir
and the new umbilical.
10. Power the machine directly into IME diagnostics mode, refer to GP 1. This will prevent the
thermals from warming up and delivering / pumping ink from the ink reservoir through the
umbilicals. When the machine has booted into IME diagnostics mode, log into diagnostics
and perform dC976 Ink Delivery Fault Recovery, to prime the umbilicals.
NOTE: If a new umbilical has been installed then run the routine a second time. A single
priming routine may not be sufficient in all cases.
11. Run the relevant diagnostic routines, refer to GP 37 Post Part Replacement Routines.
