HP 5000 manual Replace Message xx15 Replace and xx16 Replace

	Troubleshooting
	Also, after replacing the Scan-Axis Motor, perform the Scan-Axis Test
NOTE
	(⇒ Page 4-10)and check that the values are within the given limits.
	ν If the Printer still fails, replace the Main PCA ⇒ Page 8-79.
	Check Printhead Path (2)
	This is a safety shutdown and occurs whenever there is a discontinuity
	in the Printhead path, because of an obstacle, oil drops on the Encoder
	Strip, the Carriage cover touching the tube guides, etc.
	ν Switch OFF the Printer and move the Carriage from side to side
	to verify that it moves smoothly.
	ν If it still fails, check the Encoder Strip and, if necessary, clean it.
	Check Printhead Path (3)
	This is always caused by high friction in the Printhead path. Only in
	very special cases, when it happens inside the Left Hand Cover,
	incorrect assembly of the tube system causes it.
	ν Apply Oil along the complete axis of the Slider Rods with the
	User’s Slider Rods Lubrification Kit ⇒ Page 9-8.
	Replace Message "xx15 Replace" and "xx16 Replace"
	In certain circumstances (e.g. Printhead crash without Printer
	shutdown), the message "xx15 Replace" or "xx16 Replace" may
	appear on the front panel. This is due to a temporal disconnection
	between the Printhead and the flex circuit in the Carriage Assembly.
	ν Clean the Printheads and the Carriage interconnects (refer to page
	9-6, Carriage Interconnect Wiper ) and reseat the failing Printheads.
