REQUIRED MAINTENANCE
The BA-220 DualBeam laser window should be cleaned both inside and outside as needed
with a non-abrasive glass cleaner.
The internal reader optics should be cleaned at 6 month intervals with 100% denatured
alcohol and soft material such as tissue or soft toilet paper. DO NOT USE OPTICAL
CLEANING MATERIAL SOLD FOR CAMERA LENSES.
The internal optic pieces to be cleaned are:
1. Each of the 8 sides on the gold mirror wheel in the upper right corner of the reader should
be cleaned using a wet (100% denatured alcohol) tissue followed by a dry tissue. This
wheel is a metal part that is polished to a reflective surface, so use light pressure to
prevent scratches.
2. Below the gold mirror wheel is a small silver mirror to clean.
3. Below the small silver mirror is a glass lens in a silver block to clean.
REQUIRED MAINTENANCE
The BA-440 window should be cleaned as needed with a non-
abrasive glass cleaner. Optical components inside the reader should
be inspected and cleaned at 6 month intervals. These include:
•
Window glass both inside and
outside
•
8 sided gold mirror wheel
(Polygon)
•
Small mirror below gold wheel
(Polygon)
•
“Fisheye” lens in the silver block
below the small mirror
Optics should be cleaned with 100% denatured alcohol and soft
material such as Kleenex® or cotton balls. DO NOT USE LENS
CLEANING MATERIAL or OPTICAL WIPES. These will scratch the
metal of the gold wheel and degrade reader performance. Cleaning is
best accomplished by following these steps:
1. Remove 6 flanged nuts from bottom of reader.
2. Lift hood/cover straight up off of the reader.
3. Clean inside/outside the window glass on the reader hood/cover.
4. Clean all 8 mirror sides on the gold wheel (polygon).
5. Clean the small mirror directly below the gold wheel (polygon).
6. Clean the lens in the receiver block located below the small mirror.
7. Replace Desi-Paks if necessary.
8. Replace the reader hood cover over the unit.
9. Reinstall and tighten the 6 flanged nuts on the bottom of reader.
Do not adjust or remove any hardware not specified in these
directions. Any change to the optical alignment may result in poor
reader performance. If you have questions contact 800-528-9167.
