Barcode Reader Required Maintenance

BAI barcode readers are optical devices and must be able to “see” the decal in order to read

it. Accordingly, the optics and window must be reasonably clean to get the best performance.

The only required maintenance on the readers involves cleaning the window and optics. No

adjustments or alterations are required or allowed. Routine maintenance tasks are separated

below into external (outside of the reader) and internal (inside the reader) cleaning.

Exterior Maintenance:

The outside of the reader window should be cleaned as needed. The interval between

cleanings will depend on the environment where the reader is located. Using glass cleaner on

the exterior is fine, as we do not intend to place a decal on the reader window. For best

performance, clean the window whenever it appears to be dirty and also clear away any

obstructions such as webs, insect cocoons or nests.

Internal Maintenance:

At six month intervals the optics on the inside of the reader should be cleaned and inspected.

While the reader is open for cleaning the desiccant bag (to control humidity) should be

discarded and replaced with a new one. The preferred cleaning agent is 100% denatured

(wood) alcohol, which can be found in the paint section of most hardware or building supply

stores. Do not use rubbing alcohol, it contains 70% alcohol and 30% other stuff that

does not evaporate. We are trying to remove junk from the optics, not add to the mess. Use

soft tissue such as Kleenex® or soft toilet paper to clean the reader.

Warning: Do not use optical cleaning material for camera lenses. This is intended for use

on glass and will scratch the metal optics in the reader. Also, soft fabric such as cotton is not

recommended, metal bits or dirt tend to catch in the material and scratch the metal optics.

Recommended cleaning supplies:

100% denatured alcohol

Soft tissue such as Kleenex® or soft toilet paper

Follow these general steps to perform the interior maintenance:

1. Open the reader.

2. Locate humidity card and look at the circles. If all are pink, the desiccant bag must be

replaced. Be sure to do this first, if you delay the card will start to measure and report

the humidity of the outside air. We are only concerned with humidity inside the reader.

3. Remove the old desiccant bag and humidity card. They can be disposed of in the

trash, there are no harmful chemicals in them.

4. On the BA-220, remove the decoder module for cleaning. On the BA-440 the decoder

module can be cleaned in its normal position.
