step-by-step removal/assembly procedure is provided in this section. On the left page you will

2.2 Precautions
Observe simple, common sense rules and procedures whilst servicing the unit. They include,
but are not limited to the following:
• The base of the unit has been assembled on a fixture to assure straightness all along the y-
axis. To keep this: DO NOT REMOVE THE SIDE PLATES NOR THE Y-GUIDING.
• Unplug the line cords and host cables before transporting the unit to other places.
• Reassemble ALL parts (screws, ferrite shield, etc.) to maintain EMI integrity, and guide the
loose wires afterwards with tie-wrap in the same manner they were before
• Watch for sharp edges on the metal strips etc.
• When testing the cutter, make sure that the base plate is horizontal (otherwise flat cable
tool carriage will get caught).
• When the covers are off or open:
• The printed circuits boards are electrostatically sensitive; use the proper handling
techniques. Make sure no screws or washer are left behind on the printing plate, they can
cause short circuits which can damage the circuits boards.
• Keep sensors free of scratches and dirt.
• Keep the guiding, at least dirt free where the wheels of the carriage pass.
