摘要： A recording apparatus includes a print head, a recovery unit, a type obtaining unit, a threshold obtaining unit, and a calculation unit. The print head forms an image by applying a recording material to a recording medium. The recovery unit performs a recovery operation for recovering an ejection state of the print head. The type obtaining unit obtains a type of the recording medium on which the image is to be recorded. The threshold obtaining unit obtains a threshold for performing the recovery operation corresponding to the obtained type of the recording medium. The calculation unit calculates a count-up value by adding, in response to recording on the recording medium, an addition value set for each of types of recording media. The recovery operation is performed in a case where the count-up value calculated by the calculation unit exceeds the threshold obtained by the threshold obtaining unit.

摘要： A recording apparatus includes a conveying unit, a supporting unit, and a static elimination unit. The conveying unit conveys a recording medium in a first direction to a recording area where recording is performed by a recording unit. The supporting unit supports the recording medium conveyed by the conveying unit and includes an abutment surface that abuts the recording medium when the supporting unit supports the recording medium. The static elimination unit eliminates static from the recording medium in a static elimination portion. The static elimination portion is not provided at a position opposed to the abutment surface and is provided at a position not opposed to the abutment surface in the supporting unit.

摘要： For a printing apparatus, a first conveyance speed for a first printing medium is determined according to first print data to be printed on the first printing medium and a second conveyance speed for a second printing medium is determined according to second print data to be printed on the second printing medium that follows the first printing medium along a conveying path. In a case where the second conveyance speed is equal to the first conveyance speed, a conveyance operation of the second printing medium is started before the first printing medium is discharged from the conveying path. In a case where the second conveyance speed is different from the first conveyance speed, the conveyance operation of the second printing medium is started after the first printing medium is discharged from the conveying path.

摘要： A recording apparatus includes a conveyance unit, a conveyance path, a double-sided conveyance path, and first and second charge eliminators. The conveyance unit conveys a recording medium having first and second surfaces in a first direction through the conveyance path to a recording area where recording is performed by a recording unit on the first surface. The recording medium then passes through the double-sided conveyance path before recording is performed on the second surface. The first charge eliminator eliminates charges from the first surface and is disposed at a position downstream of a junction between the conveyance path and the double-sided conveyance path in the first direction and upstream of the recording area in the first direction. The second charge eliminator eliminate charges from the second surface and is disposed downstream of the junction in the first direction and upstream of the recording area in the first direction.

摘要： The present invention is to provide a printing apparatus capable of correctly detecting an origin of a conveying roller for conveying a print medium at the time of its rotation with a simple configuration that does not accompany an increase of cost. For this purpose, the printing apparatus is equipped with a lock mechanism (a lock link lever) for stopping rotation of the conveying roller at a predetermined rotational position and saves a count value of a rotation amount of the conveying roller when the conveying roller is locked by the lock mechanism concerned as origin information. After this, driving of the conveying roller is controlled based on the saved origin information and a phase of rotation of the conveying roller obtained from the count value of the conveying roller.
