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

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.

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)
