Ink supplying system for ink jet printer, ink supplying method for ink jet printer, and ink jet printer

摘要

An ink supplying system has a first pipe having one end that connects to a main ink tank storing ink containing no air and another end that removably connects to a primary auxiliary ink tank that receives ink from the main ink tank. A second pipe has one end that removably connects to the primary auxiliary ink tank. An ink jet head is connected to another end of the second pipe for performing printing by ejecting ink on a printing medium. A secondary auxiliary ink tank has a capacity smaller than that of the primary auxiliary ink tank and is selectively exchangeable with the primary auxiliary ink tank for removing air in the ink supplying system prior to printing by the ink jet head. The secondary auxiliary ink tank has a connection pipe that removably connects to the another end of the first pipe and to the one end of the second pipe in fluid communication therewith. The connection pipe has the same sectional area as that of the first and second pipes.
