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-220 laser 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 removing the decoder module from the reader
as follows:
1. Remove wiring harnesses from decode module at J1, J5, and J13.
2. Remove 4 nuts securing the decode module to the main board and
remove it from the reader.
3. Clean the inside window glass on the reader enclosure.
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. Place decode module back in the reader enclosure. Reinstall the 4
nuts and tighten securely.
8. Reinstall the wire harnesses at J1, J5, and J13. Do not loosen or
remove any hardware other than that specified in these directions.
Any alteration to the laser alignment may result in poor reader
performance. If you have a question contact BAI at 800-528-9167.
