摘要:
A porous absorbent can be formed using recycling materials, which makes it possible to provide at lower costs an excellent capability of absorbing ink or the like, as well as an excellent handling performance. The porous absorbent contains at least virgin fiber, old paper fiber of waste newspaper, and hemp fiber, and an ink jet recording apparatus is provided with such porous absorbent for absorbing waste ink discharged from the recording head thereof.

A recording apparatus is capable of preventing both contamination on a recording surface due to a contact of a recording medium on an ink discharging surface even when recording on the recording medium with a concave/convex portion and an ill-discharged state of an ink. The recording apparatus has a feeding unit for feeding a recording medium and a recording head as a recording unit for recording an image on the recording medium fed by the feeding unit. A first guide member (shaft) and a second guide member that serve as a correcting mechanism are provided upstream in a feeding direction from the recording head, for correcting the concave/convex portion of the recording medium.

In an ink jet recording apparatus having an ink jet head, an ink discharge from the head is executed to maintain and recover the discharge performance thereof. A cap is located opposite to the ink jet head when the maintaining and recovering ink discharge is performed, and receives the discharged ink. A waste ink tank receives ink exhausted from the cap. An ink pump transports ink received by the cap to the waste ink tank by performing idle suction. The number of times the idle suction is performed is variable, and is controlled by a control unit. The idle suction includes idle suction for recovery suction and idle suction for idle discharge. The idle suction for recovery suction is characterized as suction of ink when the cap caps the ink jet head, and the idle suction for idle discharge is characterized as suction of ink when the cap is communicated with atmosphere. The number of times of the idle suction is less for the idle suction for idle discharge than for the idle suction for recovery suction.

An ink jet recording apparatus having an ink jet recording head and a cap. The apparatus includes a recording head, the recording head having a discharge port face with a discharge port arranged thereon, and a recovery device, the recovery device including the cap for covering the discharge port face, the cap having an interior and including a body portion and an edge portion opposing the discharge port face and having a leading end, the edge portion including an elastic member for covering a periphery of the discharge port, wherein during a capping operation a plane defined by the leading end of the edge portion is not parallel to the discharge port face and the edge portion is not displaced in a direction different from a capping direction between the cap and the ink jet recording head. A part of the leading end of the edge portion in contact with the discharge port face defines a contact portion between the leading end of the edge portion and the discharge port face, and the contact portion increases during the capping operation as the leading end approaches the discharge port face and gradually comes into contact with the discharge port face, the discharge port face being capped with the entire leading end of the edge portion in contact therewith when the capping operation is terminated.
摘要:
An ink jet recording apparatus includes a recording head for recording by discharging ink on a recording medium and a plurality of waste ink storage members connected in series for receiving waste ink from only one recording head and provided within empty space in the apparatus. The waste ink is exhausted by a discharge recovery process in order to maintain a state of ink discharge in said recording head at least in a good condition. Each waste ink storage member includes an aperture on its surface covered with a breathable fabric to allow air into the ink storage member.

The present invention provides an image recording apparatus with an image recording unit for recording an image on a recording medium, a first conveyor for conveying the recording medium to an image recording portion of the image recording unit while bending the recording medium along a drive convey roller by means of the drive convey roller, and a second conveyor for conveying an elongated recording medium having a plurality of pin holes to the first conveyor. A guide capable of changing a contact area between the recording medium and the drive convey roller at a curved portion of the recording medium along the drive convey roller is also provided.
摘要:
A discharge maintaining and recovery apparatus which maintains and recovers a state of ink discharge from a recording head which discharges ink on a recording medium. The apparatus comprises an ink receiver capable of receiving ink, and a transporting device which connects the ink receiver to an exhaust ink receiving member. The ink receiving member receives ink exhausted by the discharge maintaining and recovery process and the transporting device transports ink to an exhaust ink receiving member. In addition, a controller controls a first discharge maintaining and recovery process for exhausting ink by driving the recording head, and a second discharge maintaining and recovery process for exhausting ink by driving the transporting device.
摘要:
A recording apparatus performs recording with an ink jet recording head that is capable of ejecting ink onto a recording medium. The recording apparatus includes an ink receiving section disposed at a position to be able to oppose an orifice-formed face of the recording head, a preliminary ejection unit for causing ink ejection from discharging orifices toward said ink receiving section by driving said recording head to remove causes of defective ink ejection, an absorption unit for absorbing ink remaining in the ink receiving section as a result of ink ejection by the preliminary ejection unit, and a dry absorption control unit. The dry absorption control unit causes ink absorption by driving the absorption unit when a number of preliminary ejection caused by the preliminary ejection unit, from the time of an absorption previously executed by the dry absorption unit during recording, exceeds a predetermined number.
