Precautions
Observe simple, common sense rules and procedures whilst servicing the unit. They include, but are
not limited to the following:
1.
 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 the covers are off or open:
 The printed circuits boards are electrostatically sensitive; use the proper handling
techniques.
 Keep sensors and reflection plates free of scratches and dirt.
 Keep the guiding, at least dirtfree where the wheels of the carriage pass.
