2.3 Daily
The lint/waste box on the instrument should be cleaned daily. The
vacuum on the box is relieved using the vacuum
ON/OFF switch
on the top.
Use the handles to open the lint/waste box doors. Remove all
fibers from the lint box by hand. Close the door when finished.
Clean the filter inside the waste box with a brush (or vacuum
cleaner). Make sure all loose material is removed.
Upon completion, close the door. The door MUST be closed for
proper operation.
Clean the color window with a soft, damp cloth (do not use
abrasives or corrosive agents).
Inspect the computer's cooling fan filters and clean if necessary.
Inspect the system’s vacuum motor filter and clean it with a brush
or vacuum as needed.
Inspect the rear door fans and filter. Clean if necessary.

Calibration Tile Care
The calibration tiles are the reference for all color and trash measurements on
the colorimeter.
When calibration tiles are not maintained in good, clean
condition, they can affect system calibration. Proper calibration is essential to
produce accurate testing results. Often, when a significant drift of Rd or +b is
noted while testing, calibration tile condition is responsible.
Uster recommends that users follow the guidelines below.
•
The tile set assigned with the unit should STAY with the unit. The tile set
will normally maintain its calibration value throughout the life of the
instrument. It is recommended that each set be checked against a
master tile set every two to three years. This is to allow re-adjustment in
the unlikely event that the Rd or +b values change or shift.
These small
shifts are usually minimal when compared to a shift in color grade.
