Maintenance Procedures
The DenOptix QST System is designed for many years of trouble-free operation. It is
manufactured from the highest quality components to ensure excellent performance.
Maintenance that can be performed by the operator is minimal.
Cleaning the System
If the scanner, imaging plates or carousel becomes contaminated, clean in accordance with the
directions given on page 4-10,”Preparing for the next patient”. If, however, a component merely
becomes soiled, clean as follows:
Cleaning the Scanner
Turn off the DenOptix QST scanner, as described on page 4-10, before cleaning.
Wipe the outside surfaces with a paper towel dampened with a cold sterilant
solution or household, non-abrasive cleaner (window cleaner works well). DO NOT
SPRAY OR SOAK THE SCANNER. Wipe the inside of the carousel well with a very
slightly damp cloth. Be careful not to allow running or dripping solvents into the
DenOptix QST scanner. This could cause damage to the electronics inside. Allow to
air dry before plugging in or turning back on.
Cleaning Imaging Plates
Imaging plates should be handled carefully. For the best images, take care not to
scratch them and keep them dust-free. Use the following procedure to clean them:
1. Use lint-free, 100% cotton gauze (not cotton balls). Gently wipe the cotton
gauz
e over the dry imaging plate surface. Wipe back and forth and then in a
circular motion.
2. To clean any remaining stains, dampen the gauze in anhydrous (water-free)
isopropyl alcohol and wipe using the same motion as above.
3. Completely dry the surface by wiping with another piece of cotton gauze.
Ensure that the imaging plate is completely dry before use.
