In a recovering apparatus for recovering ink ejecting ports forming a plane of an ink jet head, an ink absorbing member is disposed inward of a cap and proximate to the ink ejecting ports, facing the ink ejecting ports at a predetermined distance therefrom. Large ink droplets or water droplets adhering to the ink ejecting ports are then absorbed in the absorbing member. Thereafter, the plane of the ink jet heads with the ink ejecting ports is cleanly wiped by a wiping member, thereby preventing scattering of ink droplets or water droplets away from the ink ejecting ports. A trough is located adjacent to each head, and the recovering apparatus is disposed with respect to the trough so that a distance between the recovering apparatus and the ink jet head can be reduced, thereby permitting a compact arrangement of the recovering apparatus and the ink jet head.

A printing medium feeding apparatus comprises a conveying belt, on which a roll-shaped printing medium is placed with the lower surface of the roll being in contact therewith to unwind the outer periphery of the roll. With the arrangement, setup of the roll to the feeding apparatus is completed easily by only placing the roll onto the conveying belt, as compared with a construction in which the center of a roll is rotatably supported. It is also possible to omit or simplify a transmission mechanism such as a train of reduction gears that is necessary for the case of central driving. Further, it is also possible to feed a constant amount of length at a constant drive speed irrespective of radius of the roll.

A printer includes an ink jet head, a recovery unit, a moving unit, a conveying unit and a cover. The ink jet head performs printing on a printing medium and has an ink ejection port on an ejection port forming surface. The recovery unit is used for a recovery process for maintaining an ink ejection state of the ink jet head in a good condition. The recovery unit includes a cap for covering the ejection port forming surface, a wiping member for wiping the ejection port forming surface, and an absorbing member for receiving ink ejected from the ejection port of the ink jet head. The moving unit moves the recovery unit to a position where the recovery unit faces the ink jet head and to a position where the recovery unit does not face the ink jet head, the ejection forming surface of which is oriented toward the printing medium. The conveying unit conveys the printing medium to be printed by the ink jet head. The cover contains the ink jet head and the recovery unit. The cover is arranged to be opened so that a conveying path of the conveying unit appears and to be closed to cover the conveying path.

In a printer employing an ink-jet system, for appropriately managing loading and unloading of an ink cartridge and waste ink and for obtaining appropriate ink supply system for an ink-jet head, an ink storage chamber and a waste ink storage chamber of the ink cartridge is formed integrally. Most part of the waste ink storage chamber is filled with an absorbing member. Also, at a portion where a supply needle is pierced and removed at the front end face of the cartridge, an ink absorbing member is provided. Also, among two stage structure of the waste ink storage chamber, a portion where the absorbing member is not present is defined by a partitioning wall to detect the ink exuded from the absorbing member and stored in the portion beyond the partitioning wall is detected by a detection electrode. On the other hand, when the ink is forcedly supplied from the ink strage chamber to the ink-jet head by driving the tube pump in clockwise direction, the ink supply is performed via a buffer tank. Therefore, pulsation of the ink pressure due to driving of the tube pump will not affect for the ink-jet head to make the pressure at the ink-jet head stable to satisfactorily perform ejection recovery process.

A printer having an ink container, an ink jet head, and an ink storage container for temporarily storing ink to be supplied from the ink container to the ink-jet head, the ink storage container having a closable air communicating portion communicating with ambient air. A first ink path connects the ink container to the ink storage container, defines a flow of ink from the ink container to the ink storage container, and is provided with a one-way flow restricting member for permitting only a flow of ink in a direction of discharge from the ink container. A second ink path connects the ink storage container to the ink container and defines a flow of ink for returning an excess amount of ink over a predetermined liquid amount in the ink storage container to the ink container. An opening/closing member opens and closes the air communicating portion to ambient air. A buffer container is provided at a portion of the first ink path between the one-way flow restricting member and the ink storage container and is capable of maintaining a predetermined liquid amount. A transfer member transfers ink from the buffer container and is provided at a portion of the first ink path between the buffer container and the ink storage container.

A printing apparatus is capable of freely selecting a plurality of sheet feeding units each having a different controlling method. It is discriminated as to which one among plural kinds of sheet feeding units is fitted, and printing and a motor for a sheet feeding-unit are controlled based on the result of the discrimination from an output from a sensor disposed on the sheet feeding unit. Especially, in the case that a roll shaped paper feeding unit is fitted, it is judged that a printing medium reaches the position where printing can be started when a TOF sensor detects black color, and in the case that a cut sheet feeding unit is fitted, it is judged that the recording medium reaches the position where printing can be started when the TOF sensor detects white color.

An ink jet printer comprises a wiper member for wiping the surface of the ink jet recording head. The ink jet recording head and the wiper member move in the same direction each other to wipe the surface of the ink jet recording head by one operation. In this way, the stabilized wiping is always possible to keep the head surface in an appropriate condition of ink discharges, hence obtaining images in beautiful print quality with the stable ink discharges.

A cleaning method for removing a recording ink from a surface of a recording material conveying belt of a recording apparatus. The method includes the steps of detecting a recording material jam; press contacting a cleaning member to a surface of the recording material conveying belt in response to the detected jam, thus removing from the belt surface an improper discharge of recording ink; and separating the cleaning member from the surface of the conveying belt after cleaning for a period of time. The period of time is determined based upon an amount of the recording ink discharged onto the conveying belt surface.
