Problems solved by technology

However, it is difficult to reliably wipe off the ink mist adhering to the entire area of ​​the nozzle surface because the ink mist adhering to a position away from the ink overflow cannot be sufficiently redispersed.

Embodiment 1

[0122] The linear speed (moving speed) of the wipers 35a to 35c in the ejection wiping operation when the recording heads 17a to 17c of the first embodiment are returned to operation, and the ink nozzles 18 passing through the wipers 35a to 35c are compared. The difference in the stretching effect of the ink when the ejection amount of the ink was changed was investigated. First, an experimental machine was produced in which wipers 35a to 35c were mounted on a carriage 31 that reciprocated along the ink discharge surface F of the recording heads 17a to 17c and moved in the direction of approaching or separating from the ink discharge surface F. The test machine was obtained by attaching a rubber scraper made of EPDM (Shore hardness 60, impact resilience about 60%) having a width of 30 mm, a height (protrusion amount) of 7 mm, and a thickness of 1.5 mm.

Embodiment 2

[0132] The linear speed (moving speed) of the wipers 35a to 35c in the ejection wiping operation when the recording heads 17a to 17c of the first embodiment are returned to operation, and the ink nozzles 18 passing through the wipers 35a to 35c are compared. The difference in the ink mist removal effect when the ink ejection amount was changed was investigated. The structures of the recording heads 17a to 17c and the wipers 35a to 35c, and the composition of the ink 22 are the same as those of the first embodiment.

[0133] As an experimental method, after ink mist is attached and dried on the highly waterproof ink ejection surface F in advance, the linear velocity of the wipers 35a to 35c and the ink from the ink nozzles 18 passing through the wipers 35a to 35c are compared. The wiping degree of the ink mist adhering to the ink ejection surface F when the ejection wiping operation and the ink wiping operation were performed while the ejection amount was changed was observed. ...

Embodiment 3

[0138] The linear speed (moving speed) of the wipers 35a to 35c in the cleaning and wiping operation when the recording heads 17a to 17c of the second embodiment are restored, and the ink nozzles 18 that are passing through the wipers 35a to 35c are adjusted. The flow rate of ink coming out (by pushing down Figure 7 The difference in the stretching effect of the ink when the flow velocity of the ink flowing in the second supply channel 25 was changed by the piston 21b was investigated. The structures of the recording heads 17a to 17c and the wipers 35a to 35c, and the composition of the ink 22 are the same as those of the first and second embodiments.

[0139] In addition, when the wipers 35a to 35c were brought into pressure contact with the highly waterproof ink discharge surface F so that the overlapping amount of the wipers 35a to 35c and the ink discharge surface F was 1mm, the wipers 35a to 35c were visually observed. The linear velocity of 35c and the flow velocity of...

Abstract

A recording-head recovery system includes a wiper, a drive mechanism, and a control portion. The control portion is capable of performing a recording-head recovery operation which performs successively: a purged ink placing operation in which ink is forcibly pushed out of a ejecting nozzle and the purged ink is placed onto a nozzle region; a ejecting wipe operation in which the purged ink is wiped away by moving the wiper along an ink ejecting surface, applying and spreading the ink over the ink ejecting surface by ejecting the ink from an ejecting nozzle in synchronization with timing when the wiper is passing the nozzle region; and a ejected ink wiping operation in which the ejected ink applied and spread over the ink ejecting surface is wiped away.

Description

technical field [0001] The present invention relates to an inkjet recording device that performs recording by ejecting ink onto a recording medium such as paper, and more particularly to a recording head recovery system that wipes ink with a wiper after forcibly ejecting ink from a nozzle of the recording head. Removes ink adhering to the ink ejection surface. Background technique [0002] Recording devices such as facsimile machines, copiers, and printers record images on recording media such as paper and OHP sheets. According to the recording method, they can be classified into inkjet type, line dot type, and thermal type. In addition, the inkjet recording method can be classified into a tandem type which performs recording while scanning the recording head on the recording medium, and a line head type which is fixed on a The recording head on the main body of the device performs recording. [0003] The line head type inkjet recording apparatus has a line head type inkje...
