摘要： To shorten the time to be taken to start executing a process to handle conveyance trouble of a print medium after the occurrence of the conveyance trouble, a printing apparatus of the present invention, upon sensing of conveyance trouble by a sensing unit during a printing operation, stops the conveyance of the print medium in the conveyance trouble and any print medium located upstream of it, and moves a printing head from a first position at which the printing head performs printing on a print medium to a second position to which the printing head is retreated from the first position, in parallel with a discharge operation for conveying, to a discharge unit, any print medium located downstream of the print medium in the conveyance trouble.

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： A printing apparatus includes a first feeding part configured to feed print media from a first support part supporting the print media, a second feeding part configured to feed print media from a second support part supporting the print media, and a print head configured to print on the print media fed by the first feeding part or the second feeding part. Further, the printing apparatus includes a first conveying path where the print media fed by the first feeding part are conveyed to the print head, and a second conveying path where the print media fed by the second feeding part are conveyed to the print head. At least a part of the second feeding part protrudes in a predetermined spatial area within the first conveying path during a feed operation of feeding print media from the second support part.

摘要： An object is to provide a liquid ejecting apparatus that enables a liquid storage container to be properly and easily refilled with a liquid from a liquid refilling container without causing color mixture in the liquid storage container. The liquid ejecting apparatus includes liquid storage containers each configured to feed the liquid to a liquid ejecting portion and liquid refilling containers each configured to refill the liquid storage container with the liquid. A first fitting unit is provided around a liquid injection port in each of the liquid storage containers. A second fitting unit is provided around a liquid pour-out port in each of the liquid refilling containers. The second fitting unit is fitted to the first fitting unit to enable the liquid to be delivered from the liquid pour-out port to the liquid injection port.

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 motor control method performed by a controller includes monitoring a motor load of at least one of a plurality of motors including a first motor and a second motor driven by one common power source having a protection circuit, wherein the protection circuit is operated to shut down the power source in a case where a current value of the power source continues to exceed a threshold during a period Tg, and stopping motor drive in a case where the monitored motor load continues to exceed the threshold during a period Tn, which is shorter than the period Tg. In addition, monitoring of the motor load is skipped during acceleration operations of the first motor and the second motor when both the first motor and the second motor are driven, and then monitoring of the motor load is restarted.

摘要： A printing apparatus according to the present invention includes a feeding unit, a conveying unit, a printing unit, and a control unit. The control unit performs a successive feeding operation. An operating state of the feeding unit changes between a first operating state and a second operating state in which a feeding stop is more unstable than that in the first operating state, in a period from a start of feeding a printing medium until the printing medium reaches the conveying unit. In the successive feeding operation, a subsequent printing medium is fed without stopping until a leading end of the subsequent printing medium reaches a stoppable position. The stoppable position is arranged on an upstream side of the conveying unit. The subsequent printing medium can be stopped in the first operating state at the stoppable position.
