Ink jet recording apparatus

摘要

An ink jet recording apparatus is equipped with an upstream side conveyance unit arranged on a conveyance upstream side of a recording head and a downstream side conveyance unit arranged on a conveyance downstream side thereof. The ink jet recording apparatus obtains, by recording a test pattern on a sheet, a conveyance correction amount when conveyance is performed solely by the downstream side conveyance unit. The ink jet recording apparatus includes a control unit which, when effecting an arbitrary recording, effects control such that, when a sheet trailing edge leaves the upstream side conveyance unit, a rotating position of a drive side roller of the downstream side conveyance unit is the same as the rotating position of the drive side roller when the test pattern is recorded.

主权项

1. An ink jet recording apparatus comprising:
a recording head configured to record an image on a recording medium; a first roller arranged upstream of the recording head in a conveying direction and configured to convey the recording medium; a second roller arranged downstream of the recording head in the conveying direction and configured to convey the recording medium; an obtaining unit configured to obtain, in a state in which a sheet is not conveyed by the first roller and is conveyed by the second roller, a conveyance correction amount of the second roller by causing the recording head to record a test pattern on the sheet; a storing unit configured to store, in a case where the recording head is caused by the obtaining unit to record the test pattern on the sheet, a test-pattern rotating position of the second roller of when a trailing edge of the sheet passes the first roller; and an adjusting unit configured to adjust, in a case where recording of an image on a recording medium is performed by the recording head, a rotating position at which the first roller starts conveyance of the recording medium so that a rotating position of the second roller of when a trailing edge of the recording medium passes the first roller matches the test pattern rotating position.
