The attached document talks about the most common issues observed while operating the Zing engraver as well as their most common solutions. Please be sure that the engraver is powered OFF before performing any of the
procedures outlined in this document.
Y Axis Too Far Forward on Boot
If the Y Axis of the Engraver begins too far forward, or does not go all the way to the back of the
engraver during the boot process, it is likely that the Home Position Sensor is blocked by debris. To clear
the debris, locate the sensor unit on the Right hand side of the Rail and direct Compressed Air into the Y-Axis position sensor slot.
X Axis Makes Grinding Noise on Boot
If the X-Axis of the Engraver reaches the left hand side of the Rail and makes a grinding noise, or does
not go all the way to the right hand side of the engraver during the boot process, it is likely that the
Home Position Sensor is blocked by debris. To clear the debris, locate the sensor unit on the Right hand
side of the Rail and direct Compressed Air into the X-Axis position sensor slot.
X Axis Skewing and Slanting
If the user is experiencing ‘Slanting’, ‘Skewing’, ‘Waviness’, ‘Stair Stepping’ or ‘Losing Home’ during an
engraving operation, it is likely that the belt has lost tension. Remove the Left hand side cover of the
engraver and activate the Automatic Belt Tensioner on the right hand end of the Rail.
If the belt tension does not completely address the issue, the belt may be worn and will require
replacement.
Double Image
Horizontal
If the user is experiencing ‘Double Image’ or ‘Ghost Images’ where the images are directly horizontal
from each other, it is likely that the belt has lost tension. Remove the Left hand side cover of the
engraver and activate the Automatic Belt Tensioner on the right hand end of the Rail.
If the belt tension does not completely address the issue, the belt may be worn and will require
replacement.
Vertical
Vertical double imaging can come from lens carriage not rolling straight in the track on the rail. Attempt
to re-seat the lens carriage rollers back into the roller tracks. If that does not fix the issue, remove the
Lens Carriage from the engraver and inspect each of the carriage roller bearings for flat spots. Replace
any suspect rollers.
Diagonal
If the images positioned are diagonally from each other it is likely a problem with one of the engravers
Optics. Start by checking for Scratches or Cracks in any of the optics. If Optic damage can be eliminated,
check for Optic Stability. Make sure that all of the optic bezels for the Lens and Carriage Mirror are
threaded properly and screwed in tight. Check for any excess vibration in the movement of the Rail, lens
carriage or belts and be sure that the Mirrors on the Left side of the engraver are mounted properly and
are not loose.
Laser Cuts Out
The most likely cause for a laser to cut out is a loose or vibrating interlock. Begin checking the interlocks
by opening the top door of the engraver and checking to be sure that both of the silver Interlock
Magnets are still in place and are not loose. Next check the interlock sensors under the edge of the door
opening of the engraver. Make sure that both sensors are screwed in place and stable. Check Interlock
LED on the Right side of the engraver, it should illuminate when the door is closed.
The next likely reason for laser fire to cut out during operation is Overheating. Start by ensuring that the
left side of the engraver is clear of obstructions. The Zing engraver exhausts hot air from the laser tube
out of the bottom of the left side panel. In order to cool properly there must be no obstructions on the
left side of the engraver for 12 to 24 inches.
After insuring that the engraver can exhaust hot air, check that the Heat Sinks on the Laser Tube are not
clogged with debris. Open the left side panel and direct air at the Heat Sinks (‘fins’) on the laser tube
until they are clear of debris.
If after clearing the side and heat sinks of debris and obstructions the laser is still cutting out, remove
the rear panel on the engraver and locate the Fan Control Board. Flip the switch on the fan control
board to “Override”. Power on the engraver and allow sitting for 15 minutes. If the laser no longer cuts
out, the fan control board may be malfunctioning and should be replaced.
Fuzzy Engraving
Horizontal
The engraver is comes calibrated from the factory for resolutions of 500 DPI. If the user is using a lower
resolution, try the engraving again at 500 DPI. If changing the DPI does not fix the issue engrave a 1” x 1”
filled raster square. Measure the width of the square (fuzzy area included). Increase the Laser Match
setting in the Configuration menu by 1. Resend and measure the square again. If the square has
increased in width, laser match must be decreased. If the square has increased in width the laser match
must be increased. Repeat until the fuzziness has gone away and the square is exactly at 1”.
If you are unable to eliminate fuzziness with the laser match setting, the laser tube may need to be
replaced.
General
General fuzziness comes from vibration. Make sure that all of the optic bezels for the Lens and Carriage
Mirror are threaded properly and screwed in tight. Check for any excess vibration in the movement of
the Rail, lens carriage or belts and be sure that the Mirrors on the Left side of the engraver are mounted
properly and are not loose.
