Error code
7,007.4x: PM_FAULT_HEADTILT_STALL
The process motor stalled while tilting the head.
7,008.4x: PM_FAULT_HEADTILT_NOT_ ENGAGED
The printhead tilt is not engaged, so it didn't tilt back properly or the printhead is stuck in
the tilted position by the tilt lock arms. The process motor gear train getting out of sync
can also cause this error.
7,009.4x: PM_FAULT_HEADTILT_PARK_ ERROR
The printhead is tilted back but not in the park arms and restrained properly. This is due
to the wiper assembly not moving up far enough for the park arms to hold it.
