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
\nprocedures outlined in this document.<\/p>\n
If the Y Axis of the Engraver begins too far forward, or does not go all the way to the back of the
\nengraver during the boot process, it is likely that the Home Position Sensor is blocked by debris. To clear
\nthe debris, locate the sensor unit on the Right hand side of the Rail and direct Compressed Air into the Y-Axis position sensor slot.<\/p>\n
If the X-Axis of the Engraver reaches the left hand side of the Rail and makes a grinding noise, or does
\nnot go all the way to the right hand side of the engraver during the boot process, it is likely that the
\nHome Position Sensor is blocked by debris. To clear the debris, locate the sensor unit on the Right hand
\nside of the Rail and direct Compressed Air into the X-Axis position sensor slot.<\/p>\n
If the user is experiencing \u2018Slanting\u2019, \u2018Skewing\u2019, \u2018Waviness\u2019, \u2018Stair Stepping\u2019 or \u2018Losing Home\u2019 during an
\nengraving operation, it is likely that the belt has lost tension. Remove the Left hand side cover of the
\n\tengraver and activate the Automatic Belt Tensioner on the right hand end of the Rail.<\/p>\n
If the belt tension does not completely address the issue, the belt may be worn and will require
\nreplacement.<\/p>\n
If the user is experiencing \u2018Double Image\u2019 or \u2018Ghost Images\u2019 where the images are directly horizontal
\nfrom each other, it is likely that the belt has lost tension. Remove the Left hand side cover of the
\nengraver and activate the Automatic Belt Tensioner on the right hand end of the Rail.<\/p>\n
If the belt tension does not completely address the issue, the belt may be worn and will require
\nreplacement.<\/p>\n
Vertical double imaging can come from lens carriage not rolling straight in the track on the rail. Attempt
\nto re-seat the lens carriage rollers back into the roller tracks. If that does not fix the issue, remove the
\nLens Carriage from the engraver and inspect each of the carriage roller bearings for flat spots. Replace
\nany suspect rollers.<\/p>\n
If the images positioned are diagonally from each other it is likely a problem with one of the engravers
\nOptics. Start by checking for Scratches or Cracks in any of the optics. If Optic damage can be eliminated,
\ncheck for Optic Stability. Make sure that all of the optic bezels for the Lens and Carriage Mirror are
\nthreaded properly and screwed in tight. Check for any excess vibration in the movement of the Rail, lens
\ncarriage or belts and be sure that the Mirrors on the Left side of the engraver are mounted properly and
\nare not loose. <\/p>\n
The most likely cause for a laser to cut out is a loose or vibrating interlock. Begin checking the interlocks
\nby opening the top door of the engraver and checking to be sure that both of the silver Interlock
\nMagnets are still in place and are not loose. Next check the interlock sensors under the edge of the door
\nopening of the engraver. Make sure that both sensors are screwed in place and stable. Check Interlock
\nLED on the Right side of the engraver, it should illuminate when the door is closed. <\/p>\n
The next likely reason for laser fire to cut out during operation is Overheating. Start by ensuring that the
\nleft side of the engraver is clear of obstructions. The Zing engraver exhausts hot air from the laser tube
\nout of the bottom of the left side panel. In order to cool properly there must be no obstructions on the
\nleft side of the engraver for 12 to 24 inches.<\/p>\n
After insuring that the engraver can exhaust hot air, check that the Heat Sinks on the Laser Tube are not
\nclogged with debris. Open the left side panel and direct air at the Heat Sinks (\u2018fins\u2019) on the laser tube
\nuntil they are clear of debris. <\/p>\n
If after clearing the side and heat sinks of debris and obstructions the laser is still cutting out, remove
\nthe rear panel on the engraver and locate the Fan Control Board. Flip the switch on the fan control
\nboard to \u201cOverride\u201d. Power on the engraver and allow sitting for 15 minutes. If the laser no longer cuts
\nout, the fan control board may be malfunctioning and should be replaced. <\/p>\n
The engraver is comes calibrated from the factory for resolutions of 500 DPI. If the user is using a lower
\nresolution, try the engraving again at 500 DPI. If changing the DPI does not fix the issue engrave a 1\u201d x 1\u201d
\nfilled raster square. Measure the width of the square (fuzzy area included). Increase the Laser Match
\nsetting in the Configuration menu by 1. Resend and measure the square again. If the square has
\nincreased in width, laser match must be decreased. If the square has increased in width the laser match
\nmust be increased. Repeat until the fuzziness has gone away and the square is exactly at 1\u201d.<\/p>\n
If you are unable to eliminate fuzziness with the laser match setting, the laser tube may need to be
\nreplaced.<\/p>\n
General fuzziness comes from vibration. Make sure that all of the optic bezels for the Lens and Carriage
\nMirror are threaded properly and screwed in tight. Check for any excess vibration in the movement of
\nthe Rail, lens carriage or belts and be sure that the Mirrors on the Left side of the engraver are mounted
\nproperly and are not loose.<\/p>\n\r\n\t\t\t
