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： An object of the present invention is to prevent the ends of print media fed continuously from colliding with each other. The present invention is a printing apparatus including: a printing unit configured to perform print operation; a detecting unit configured to detect conveyance abnormality; a conveying unit configured to convey a preceding print medium and a succeeding print medium; a conveying path having a first area including a curved portion at which a conveying direction of the print medium is curved and a second area upstream of the first area; and an opening unit capable of opening the first area of the conveying path, wherein, in a case where a leading edge of the succeeding print medium is located in the second area at the time of the detecting unit detecting conveyance abnormality of the preceding print medium, the conveying unit conveys the succeeding print medium so that the leading edge of the succeeding print medium reaches the first area.

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.
