Abstract
A blotter for ink absorption in ink-jet printers includes two parts of a cellulose fiber material, one adjacent the other and in physical contact, beneath the service station and on the base of the printer. The blotter parts have the capacity to simultaneously absorb at least the contents of four ink cartridges, and will last the lifetime of the printer. As a consequence of the blotter of the present invention, ink from leaky ink cartridges and ink overflow from ink cartridge maintenance are absorbed and contained. Over time, the water in the inks which has been absorbed by the blotter parts will evaporate and an additional volume of ink can be absorbed.
