To replace the X-Axis belt on an Epilog FiberMark laser, you must remove the X-Axis rail to allow access to the bearing guard and proper belt routing. This procedure involves three phases: removing the rail, replacing the belt, and reinstalling the rail and associated components.<\/p>\n

To complete this procedure you’ll need a phillips screwdriver, scissors, and a replacement nylon tie for the ribbon cable. The steps include removing the rail, slackening and replacing the belt, re-securing the rail, and performing final alignment checks.<\/p>\n

Procedure<\/h2>\n
    \n
  1. \n Power down and remove side panels.<\/strong><\/p>\n

    Turn off the machine and unplug it. Remove both left and right side panels by unscrewing the six screws on each side (four on the side, two on the rear).<\/p>\n

  2. \n Disconnect the air assist line.<\/strong><\/p>\n

    Remove the air assist connector from the X-Axis assembly by pressing the ring and pulling the connector free.<\/p>\n

  3. \n Unplug the white ribbon cable.<\/strong><\/p>\n

    On the right side of the X-Axis rail, depress the thumb clip on the white ribbon cable connector and pull it down to unplug.<\/p>\n

    \"Disconnecting\n <\/li>\n

  4. \n Loosen green-cased screws.<\/strong><\/p>\n

    Loosen the two green-cased screws near the right side (one near the ribbon cable, one near the X motor) and the single green-cased screw on the left side.<\/p>\n

    \"Right-side
    \n \"Left-side\n <\/li>\n

  5. \n Remove the X-Axis assembly.<\/strong><\/p>\n

    Lift both sides of the rail to free it from the brackets. Slide the left side forward to clear the chassis and lift the assembly out carefully.<\/p>\n<\/li>\n

  6. \n Slack the X-axis belt.<\/strong><\/p>\n

    On the left side of the X-Axis rail, loosen the pulley tension screws. Press the pulley toward the machine to release belt tension and retighten the screws to hold the pulley in the slackened position.<\/p>\n

  7. \n Detach the old belt from the laser head.<\/strong><\/p>\n

    Remove the screws and plates securing the belt to the lens assembly, leaving the belt routed but detached.<\/p>\n

    \"Belt\n <\/li>\n

  8. \n Install the new belt.<\/strong><\/p>\n
      \n
    1. Attach one side of the old belt to the new belt with a stapler, then pull the opposite end of the old belt to fish the new belt through the routing path.<\/li>\n
    2. Attach one side of the new belt to the lens assembly and secure with screws.<\/li>\n
    3. Cut the belt to proper length, seat under clamps, and tighten the screws.<\/li>\n
    4. Check pulley alignment; ensure the belt runs centered without rubbing.<\/li>\n
    5. Retension the belt by loosening the pulley screws, allowing the pulley to snap into position, then re-tighten the screws.<\/li>\n<\/ol>\n<\/li>\n
    6. \n Reinstall the X-Axis assembly.<\/strong><\/p>\n

      Reverse removal steps to reinstall the rail. Replace the ribbon cable tie with a new nylon tie, reconnect the air assist line, and secure all screws.<\/p>\n<\/li>\n

    7. \n Reinstall panels and final checks.<\/strong><\/p>\n

      Reattach side panels, reconnect power, and test X-Axis motion. Verify proper belt tension and alignment. For the detailed alignment procedure, refer to the FiberMark Alignment tech note linked on the right.<\/p>\n<\/li>\n<\/ol>\n<\/article>\n\r\n\t\t\t
