	• Focus carriage X-axis bearing tensioning arm		• Remove carriage from rail, check for freedom
		too tight or binding		of movement of tensioning arm. Lubricate if
				necessary. Position of tensioning arm should
				be no greater than 10 o’clock.
	If the pattern is excessive:		•	Check and/or adjust
	•	X-belt too tight	•	Check and/or replace
	• Worn or binding X-axis bearings		•	Check and/or replace
	• Worn or binding X-axis idler pulley		•	Check and/or replace
	• Worn or binding X-axis motor		• Check with Service Department
	•	Firmware needs updating
When homing, the arm slams	•	Bent Y-flag	•	Check and/or straighten
repeatedly for a few seconds	•	Dirty or faulty home sensor(s)	• Replace upper flex board (home sensor)
	•	Faulty flex cable	•	Replace flex cable
	• Faulty lower flex cable board		• Replace Lower flex cable board
When focusing, the Z-axis table only	•	Dirty or faulty Z-axis sensor	• Try to clean sensor(s) with compressed air,
moves in one direction				otherwise replace sensor
When using Autofocus, the table	•	Autofocus sensor and/ or reflector is dirty	• Clean sensor and/or reflector

bottom and gets stuck				Autofocus beam, check the sensor for only
				an illuminated green light. A red light, both
				lights, or no lights indicate a misalignment or
				dirty condition. Clean, re-check, re-align the
				Autofocus sensor.
When printing to the laser system,	•	Laser not turned on	• Turn on laser system
