ABSTRACT:
A nozzle orifice protective apparatus comprises a cap for covering an ink nozzle which cap is supplied with maintenance solution, and a maintenance solution tank for storing maintenance solution. The maintenance solution tank is made of a flexible bag and contains a specified volume of gas as well as the maintenance solution, facilitating accurate detection of the amount of solution remaining in the tank. Thus, the maintenance solution tank is simple in construction and inexpensive to manufacture.
A water-absorbing polymer is placed a waste collecting tank case so that it absorbs waste liquid such as maintenance solution and ink led from the cap into the tank case. Since the polymer which has absorbed the liquid becomes gel, replacement of the waste collecting tank case and the subsequent waste disposal are extremely simple and easy.
