In a method of adjusting record displacement of a serial printer including a recording head which records a plurality of lines at a time in the main scanning direction, a first test pattern which is formed of a plurality of line patterns spaced apart by a prescribed distance is recorded in the main scanning direction, the record sheet is fed by a prescribed amount, and a second test pattern which is formed of prescribed recording patterns is recorded. Based on the positional relations between the first and second test patterns, the feeding amount of the record sheet is adjusted. Since the feeding amount of the record sheet is adjusted based on the positional relations between the first and second test patterns, record displacement in the feeding direction of the record sheet can be adjusted easily, and the cost increase of the serial printer can be suppressed.

Cloth is successively conveyed by a supply roller and a take up roller over a platen which opposes an ink jet head selectively jetting ink. The platen has an opening formed at a surface opposing to the ink jet head, and an air suction opening behind the opening of the platen is connected to an air suction unit through an air path. At the time of dyeing, fluff on the surface of the cloth opposing to the ink jet head is sucked and laid down on the surface of the cloth by air suction by the air suction unit, and ink is appropriately jetted to the surface of the cloth from the ink jet head. Therefore, ink jet is not hindered by the fluff on the surface of the cloth at the time of dyeing. Therefore, ink drops can reach the desired position on the surface of the cloth, and satisfactory dyeing without any distortion in patterns is performed.

Featured is a fixing device provided in an image forming device that includes a heat roll, a pressurization roll, an application member and a blade member. The heat roll has a surface that is heated to a desired temperature by a heating source and the pressurization roll presses a recorded medium (e.g., a paper sheet) holding an unfixed image to the heat roll. In this way, the unfixed image is fixed to the recorded medium by passing it between the heat roll and pressurization roll. The application member applies a release agent to the heat roll for preventing adherence of the unfixed image held on the recorded medium to the heat roll, where the release agent is impregnated to the application member and applied to the heat roll by capillary action. The blade member controls the application of the release agent so it is uniformly applied to the heat roll and removes excessive release agent to be applied on the heat roll. The application and blade members are positioned so that opposing end surfaces are adjacent to each other. In a more particular embodiment, the blade member is positioned adjacent a tip of the capillary of the application member. This advantageously results in suppressing a remaining release agent upstream of the blade member by the application member and automatically controlling the amount of the release agent carried up by the application member. In this way, the application region in the tip portion of the application member is in a saturated state and the excessive supply of the release agent is limited, which leads to stabilization of the supply quantity and the prevention of excessive release agent. Additionally, such an arrangement also prevents the dripping of the excessive release agent when applying the release agent.

An ink jet recording device has heating device for heating ink at a suction pipe, a suction pump or a cap member. With this structure, an unsatisfactory operation of the ink jet recording device due to coagulation of ink can be prevented even when heat melting ink, or ink presenting plastic-flowability at the ordinary temperature, is used for the ink jet recording device.

In a non-printing state, a cap is moved toward an ink jet nozzle of a head, for sealing the same. Immediately before the cap comes into contact with the jet nozzle, a gear is rotated by a motor to drive a piston, for sucking air from the interior of the cap by a suction pump consisting of the piston and a cylinder. This sucking operation is continued until the cap comes into close contact with the jet nozzle, for sucking the ink from the head.

In a container, an ink exhausting detecting liquid permeable sponge and an ink permeable sponge are disposed with an isolation film therebetween. The ink exhaustion detecting liquid is oil based, and has a resistance value higher than that of ink, and a specific gravity smaller than that of ink. In usage, the isolation film is drawn out of the container, whereby the ink exhaustion detecting liquid permeable sponge is brought into contact with the ink permeable sponge.

A serial printer includes a carriage reciprocating in a main scanning direction, a reading sensor mounted in carriage, a timing fence arranged in the main scanning direction, a mechanism preventing movement of carriage in the main scanning direction, and a controlling portion detecting a set condition for image formation in accordance with read data of timing fence from reading sensor for controlling image formation. Controlling portion detects the set condition for image formation only in accordance with the read data of timing fence, so that detection of the set condition for image formation is enabled without increasing the size of an apparatus and cost, or without decreasing a processing efficiency in image formation.

摘要:
A sheet with an image formed thereon by an ink jet mechanism is held over the second sheet output tray. Then the sheet being held on the second sheet output tray is pushed out in the direction of discharge of the sheet by means of a rotating sheet discharge arm so that the sheet drops onto the first sheet output tray.
