Point-of-sale printers are expected to perform with little of no customer maintenance. Some of the printers are equipped with optical read/imaging systems. Given the physical nature of the hardware components and a bit harsh environment, namely optical components and paper dust etc., the images are likely to become darker and drift into regions where they are not visually acceptable. The disclosed technique defines the process of combatting the problem and ensuring a good delivered image.
