Maintenance
Cleaning the External Devices
Occasionally the scanner tip or window may become partially obstructed by ink,
paper fibers, or other particulate deposits (such as wax or varnish). To ensure
reliable scanning, you should periodically check and, if necessary, clean the tip
with a soft cloth.
Note: Damaged tips for the pen wand should be replaced. Consult your dealer
or Hand Held Products Product Service and Repair Department for
details (see
Product Service and Repair on page 5-1).
QC890 Verifier
Occasionally the view window or alignment window may become dusty or dirty.
Use a soft cloth to clean both of the windows. Since the open slot of the
alignment window is where the code is “seen,” dirt on the window does not affect
the readability of the QC890 Verifier.
Note: It is not necessary, nor is it advisable, to insert anything into the open slot
on the bottom of the QC890 Verifier.
Recertification
Sending the QC890 Verifier back to Hand Held Products periodically for a factory
calibration and re-certification is recommended; however the frequency is based
on your company’s ISO procedures regarding test and measurement equipment.
When you are ready to re-certify your QC890 Verifier, please contact Product
Service and Repair for pricing and a Return Material Authorization (RMA)
number (see
Product Service and Repair on page 5-1).
