subject: Using Infrared Inspection To Clean Flatbeds And Scanners [print this page] When the word "cleaning" is mentioned, you probably think that it"s a tedious job, which requires hours of effort. Especially, when it comes to cleaning electronic appliances, the job has to be almost perfect when dealing with the smallest parts. However, when it comes to scanners and flatbeds, there is an easy and exciting way to do the job!
To maintain scanners and flatbeds for an extended period of time, their scanning glass needs to be in top condition, meaning without dust and scratches. While you may be able to see major scratches and dirt, the fine particles may not be visible. This is why you need infrared imaging to aid in the cleaning procedure of these appliances. The process is both interesting as well as effective.To understand how this works, we first need to learn the basics of the infrared lighting.
An object is known to emit rays that are invisible to the naked eye. One these raysare infrared rays, which are based on heat emission. IR viewing devices helps convert these heat emissions into electrical images that can be displayed in the form of different colors in the screen of the computer. Thus, you can observe the problem areas inside the body of the flatbed as well as the glass of the scanner, without having to come in physical contact with it. These devicesmay project a wide temperature range and can show the smallest changesas low as 0.05 degree Celsius.
The additional infrared detector channel from the scan collects IR radiations along with resolution of three visible colors: red, green and blue. The combination of both radiation and colors is used to check for dust and scratches.
This combination works wonderfully as the three colors are invisible to infrared light, while the scratches may be seen, so the cleaning process is done smoothly. However, along with the colors,the dust particles are also missed by the IR light. This is where RGB light helps, as the dirt appears as black spots in the colored rays. Using both to your advantage, you can correct the faults.
Using infrared for cleaning is ideal to remove and reduce the effect of dust particles and harmful scratches while actually scanning the document. This results into a clear and accurate scanned image or document. Using the same technology, one may view the document placed on the glass in two different lights and correct the problems with the image using the edit tool.
With infrared technology, you can maintain your expensive scanners and get accurate images and documents from them.
