Recently, MMC has pioneered the use of advanced light sensing technology on Brother's Series 61 ink cartridges to successfully obtain a national invention patent license (Patent No.X), bypassing the blockade of international major brand technology patent barriers.
In the prior art, an optical sensing method has been widely used as one of detection methods for the amount of remaining ink or the presence or absence of ink in an ink cartridge for an inkjet printer. In most of the printers with optical sensors, the ink cartridge mounting parts are provided with sensors composed of a light emitting part and a light receiving part that are equivalent to each other. The structure ink box not only needs the buoyancy of the buoy and the light blocking component to be arranged by the precise technical buoyant force of the light shielding component, but also needs to provide a groove for accommodating the buoy, the shade and the arm for connecting the two on the casing, and the manufacturing and the structure thereof are relatively complex. At the same time, the instability of the mechanical action will cause the sensitivity of light sensing.
This technique successfully avoids the printer from still printing when the ink is used up, causing unrecoverable damage to the printer, and causing unnecessary time and paper waste to the user. Enables products to achieve less than 10% ink residue (currently 20% to 30% of products in the industry), saving more than 10% of the material cost. Focusing on optimizing design, saving investment, reducing project cost, reducing mechanical components, eliminating materials, processing, quality control, and assembly costs, saving 10% in cost compared to traditional process design, and maximizing resource savings.
