That specific code is related to the print head moving slowly from the park to the use position.
If you remove the covers you want to check these things in order as most likly causes.
1. looking at the printer from the front, on the left side, there is a steel block lower on the machine about mid way back. See if there is any ink in it. If there is you have to remove that block and clean it.
2. Check to see if any of the print head harnesses are causing the print head to bind.
3.The cleaning blade may be stuck to the print head if the printer was not shut down properly.

    · The printer was powered off in the middle of a cleaning cycle and the wiper has frozen to the printhead.

    · A Drum Maintenance Camshaft lobe is broken and holding the Maintenance Kit?s oil roller against the drum when it should be retracted to its home position.

    · Process gearbox not being aligned correctly as described in the service manual and in Service Bulletin 714.

    · A broken left or right printhead restraint.

    · Ink spilled in the roll block preventing the printhead from tilting forwards/backwards or from traveling left/right.

    · Ink or other debris under the printhead that do not allow it to fully tilt backwards or forward.

    · The printhead wiper assembly not being aligned correctly or ink spilled in the wiper tracks on either side of the printer.

    · The printhead tilt gear not being homed correctly.

    · The X-axis motor nose cone not being installed correctly.

    · The ferrite torrid on the printhead interface cable has slipped behind the printhead causing the printhead to bind when it tilts backwards.

    · The black plastic shroud on the back of the printhead is snapped off and binding the printhead when it tilts back.

It means the printhead is stuck in the tilt position by the tilt arms. If the process motor gearbox is out of sync, it'll cause this error. Steps to resolve: Reboot the printer. Verify the lock arms rotate correctly. Check for spilled ink around the printhead (did you move it without waiting for it to cool down?) Check the process motor gears for damage. Make sure they're aligned and homed correctly. Repeat for process gear box, process shaft, and drive module shaft. Verify the headtilt gear will engage. From there, run the Tilt Axis Drive test, Process Motor test, Head Maintenance Clutch test (replace clutch if failed), and Wiper drive test (replace wiper drive system if failed)
