Focus carriage looses X-axis	∙	Mechanical interference	∙ Check if focus carriage makes contact
position and slams into the left				with material or other objects
or right side of the rail during	∙	Dirty laser system	∙ Clean all optics, rails, bearings and belts
high speed raster engraving	∙	CPU overheating	∙ Clean CPU filters, correct ambient
				temperature to be within specifications
	∙	Focus carriage X-axis bearing	∙ Remove carriage from rail, check for
		tensioning arm too tight or binding		freedom of movement of tensioning arm.
				Lubricate if necessary. Position of
				tensioning arm should be no greater
	If the pattern is excessive:			than 10 o’clock.
	∙	X-belt too tight	∙	Check and/or adjust
	∙ 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 and/or replace
	∙	Firmware needs updating	∙ Check with Service Department
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
	∙	Faulty flex cable		sensor)
	∙ Faulty lower flex cable board		∙	Replace flex cable
			∙ Replace Lower flex cable board
When focusing, the Z-axis table	∙	Dirty or faulty Z-axis sensor	∙ Try to clean sensor(s) with compressed
only moves in one direction				air, otherwise replace sensor
When using Autofocus, the table	∙	Autofocus sensor and/ or reflector is dirty	∙ Clean sensor and/or reflector
moves all the way down to the	∙	Autofocus sensor is misaligned	∙ With the Z-axis table out of the way of the
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	∙	Laser not turned on	∙ Turn on laser system

responding”				control panel. Clear laser system
				memory and try again
	∙ Single file is too large for memory		∙	Purchase more memory
		installed in laser system
	∙ Bad parallel port in computer system		∙ Try printing to another printer using the
				same port
	∙ Damaged port in CPU		∙ Replace laser system’s CPU
