933 - Mirror Motor - Locks/Lost Hsync* (*Horizontal Sync) Have you gone through this exercise yet: These errors usually indicate a failure in the HYSNC signal to the printhead. Check the continuity of the cables connected to J5 and J4 on the system board. If incorrect, replace the defective cable. The voltage at J4-1 measures approximately +5 V dc.
