WARNING
	attempting any procedures to resolve the problem.
	Check Printhead Cleaner Path
	This message appears whenever the Service Station Carriage does
	not move, either because of a bad cable connection, a defective
	motor or because of some obstacle inside the Service Station.
	ν If the Printer is new, check that the Service Station cable (which is
	the grey flat cable with the grey connector) is plugged into the Main
	PCA. Make sure that the clips of the connector are closed
	completely. Check also that the Service Station cable is not damaged.
	ν In already used Printers, power OFF the Printer and try to move
	the Service Station backwards and forwards to see whether it is
	blocked. Possible causes are: Printhead Cleaners incorrectly
	positioned, damaged or, even, pieces of paper within the Service
	Station. Remove the Printhead Cleaners or the pieces of paper
	and check whether the problem persists.
	ν If the problem disappears without the Printhead Cleaners, reinsert them
	into the Service Station and see whether the problem reappears. If the
	problem reappears, replace the complete set of Printhead Cleaners.
	ν If the problem persists even without the Printhead Cleaners, then
	replace the Service Station (⇒ Page 8-67) and recalibrate the Printer.
