Maintenance
The IMAGETEAM 4400/IT4700 Imager provides reliable and efficient operation
with a minimum of care. Although specific maintenance is not required, the
following periodic checks ensure dependable Imager operation:
Cleaning the Imager's Window
Reading performance may degrade if the Imager's window is not clean. If the
window is visibly dirty, or if the Imager isn't operating well, clean the window with
a soft cloth or facial tissue dampened with water (or a mild detergent- water
solution). If a detergent solution is used, rinse with a clean tissue dampened with
water only.
The Imager's housing may also be cleaned the same way.
!
Caution:
Do not submerge the Imager in water. The Imager's housing is not
water-tight.
Do not use abrasive wipers or tissues on the Imager's window -
abrasive wipers may scratch the window.
Never use solvents (alcohol or acetone) on the housing or
window - solvents may damage the finish or the window.
Inspecting Cords and Connectors
Inspect the Imager's interface cable and connector for wear or other signs of
damage. A badly worn cable or damaged connector may interfere with Imager
operation. Contact your Welch Allyn distributor for information about cable
replacement. Cable replacement instructions are on the next page.
