This recording-medium conveying device comprises a conveying belt, the conveying belt, a belt charging unit, and a pressing roller. The conveying belt is wound around a driving roller and a driven roller so as to convey a recording medium to an image recording part. The conveying belt includes an insulating layer formed at one side contacting the recording medium. The belt charging unit is provided in contact with the insulating layer so as to charge the insulating layer with a positive charge a...

An image forming apparatus for forming an image on a recording medium by ejecting a recording liquid to the recording medium at a recording part is disclosed. The image forming apparatus includes a conveyor belt for conveying the recording medium to the recording part, the conveyor belt satisfying a relation of .gamma.>.gamma.c, wherein .gamma. (mN/m) is a static surface tension of the recording liquid at 25.degree. C., and .gamma.c (mN/m) is a critical surface tension of the conveyor belt, w...

A platen moving mechanism has a main body frame having a first recess, a head that performs processing on a sheet material, and a platen roller having a shaft portion that is inserted in the first recess of the main body frame while the sheet material is fed in a preselected feeding direction between the platen roller and the head during processing of the sheet material. A platen frame supports the platen roller and is mounted to undergo pivotal movement between an open state and a closed state....

An apparatus to control static electricity in an inkjet printer, includes a feeding roller to convey paper being fed from a paper-feeding portion to be placed under a print head; a pinch roller to rotate in contact with the feeding roller; a holder on which a shaft of the pinch roller is rotatably supported; a frame made of a metallic material, to support the holder; and a ground member to ground the pinch roller to the frame, to control the static electricity occurring in the paper passing betw...

When the trailing edge of a recording sheet is released from a nip of a first pair of rollers which hold and convey the recording sheet, on the upstream side in the conveyance path, a variance of electric power for driving the first pair of rollers is detected, and image data to be outputted to the print head is shifted to the upstream side in the conveyance direction of the recording sheet, so that the print head is driven. As a result, it is possible to prevent the positional shift of image du...

An inkjet printing system is provided, which includes a first stage mounted with a mother glass including a plurality of substrates and a plurality of alignment keys, a head unit having at least one inkjet head, an alignment key position sensor for sensing positions of the alignment keys to generate a plurality of sensing signals respectively corresponding to the alignment keys, and a transporting unit controller for aligning a position of the head unit based on a current position of the head un...

A liquid ejection head is operable to eject a liquid droplet toward a target position. A transporter feeds a first target medium toward the target position in a first direction. An ejector ejects the first target medium to the outside of the apparatus. The ejector includes a first roller and a second roller adapted to nip the first target medium transported from the target position in the first direction. A guide member is disposed at a position closer to the outside of the apparatus than the ej...

A recording system includes a first recording unit, including a recording module having a recording head and a cleaning unit which cleans the recording head, a conveying section which conveys a recording medium, and at least a second recording unit provided at a downstream side in a conveying direction of the recording medium, wherein the first recording unit records a first image portion and the second recording unit records a second image portion.

In a method for compensating for media linefeed errors in a media feed apparatus, a first correction parameter is applied during a first length of a media feed operation and a second correction parameter, which differs from the first correction parameter, is applied during a second length of the media feed operation.
