    An ink tank system in printers continuously supplies ink to a comparatively small inkjet print head. It increases the print capacity. Ink in the tank will lasts for a long time and it is refillable. How long the ink will last depends on how heavy the usage of the printer is for the user. The general warranty that companies offer for the Ink Tank system is for a period of one year or in a range of 25000 to 30000 pages.

    A multi-function printer is a type that performs multiple tasks alongwith printing such as scanning, sending fax, photo copy, automatic document feeding etc.

    Bit depth is the scanner's ability to accurately analyze and reproduce the full color spectrum of the scanned information. This increased bit depth processing helps in improving the ability to obtain detail from the darker areas of an image.

    48-bit internal, 24-bit external means that the scanner (48 bits - internal) performs the internal processing to select the best possible colors from the available shades or (palette) of colors and outputs only in 24-bit color (24 bits -external).
