Abstract: A transfer control method of continuous paper includes controlling a transfer amount of the continuous paper based on a rotational amount detected by a roller feeding amount detecting unit which detects the rotational amount of a paper feed roller, when each page of the continuous paper is printed, and when the printing on each page is completed, performing a cueing process of transferring the continuous paper until a printing start position of a next page reaches the printing position. The cueing process includes transferring the continuous paper until the continuous paper reaches a reference transfer position based on the feeding amount of the tractor detected by a tractor feeding amount detecting unit for detecting a feeding amount of the tractor and after the continuous paper reaches the reference transfer position, setting the transfer amount of the continuous paper as a target feeding amount.
Abstract translation: 连续纸的转印控制方法包括：当连续纸的每页被打印时，基于检测到供纸辊的旋转量的辊供给量检测单元检测到的旋转量来控制连续纸的转印量， 并且当每个页面上的打印完成时，执行传送连续纸的提示过程直到下一页的打印开始位置到达打印位置。 提示过程包括传送连续纸，直到连续纸基于由拖拉机供给量检测单元检测到的拖拉机的进给量到达参考传送位置，用于检测拖拉机的进料量，并且在连续纸到达参考转印 位置，将连续纸的传送量设定为目标供给量。

Abstract: A medium transporting apparatus includes an endless conveyor belt having an outer surface to which a sheet P adheres, at least two rollers, which are a first roller and a second roller, around which the conveyor belt extends. The second roller is located downstream of the first roller in a medium transporting direction. The medium transporting apparatus also includes a backing plate that supports an inner surface of the conveyor belt at a position between the first roller and the second roller. In the medium transporting apparatus, the backing plate includes a hollow-containing portion that is formed at an upstream end of the backing plate in the medium transporting direction. The hollow-containing portion has a plurality of hollows formed therein in a width direction that intersects the medium transporting direction. The plurality of hollows are formed in a support surface that supports the conveyor belt.

Abstract: A recording device includes a recording unit configured to perform recording to a medium, a conveyance belt disposed facing the recording unit and configured to convey the medium, a first blade and a second blade configured to make contact with the conveyance belt and scrape out a residual of the conveyance belt, and a switching mechanism configured to switch the first blade and the second blade. When the first blade is moved to a first position where the first blade makes contact with the conveyance belt, the control unit moves the second blade to a second position where the second blade is separated from the conveyance belt, and when the second blade is moved to the first position where the second blade makes contact with the conveyance belt, the control unit moves the first blade to the second position where the first blade is separated from the conveyance belt.

Abstract: A printing apparatus includes a print section configured to perform printing on a medium, a supply path configured to supply the medium toward the print section, a feeding roller configured to feed the medium along the supply path from an upstream side to a downstream side in a transport direction, a toothed roller provided on the downstream side of the feeding roller in the transport direction, a drive source configured to rotate the feeding roller and the toothed roller, and a controller configured to control driving of the drive source. The controller performs rotation control for rotating the feed roller prior to the rotation of the toothed roller with which the medium has collided. The controller performs the rotation control when the controller determines that the grammage of the medium is greater than or equal to a threshold value.
