Abstract
A paper feeder, a control method thereof, and an image forming apparatus having the same are provided. The paper feeder includes a moving member to push paper loaded on one paper loader to another empty paper loader. With regard to operation of the moving member, the stop time of the moving member may be variable based on a paper size input by a user, which enables a stop position of the moving member to be automatically adjusted based on the paper size, resulting in enhanced user convenience.
Claims19
A paper feeder comprising:
- a paper feeder housing provided in an image forming apparatus;
- a first paper loader placed in the paper feeder housing to load paper to be fed into the image forming apparatus;
- a second paper loader placed in the paper feeder housing to load paper to be fed into the first paper loader;
- a movement unit having a moving member to move the paper loaded on the second paper loader to the first paper loader;
- and
- a controller to control the movement unit such that the moving member is moved to move the paper loaded on the second paper loader to the first paper loader if the first paper loader is out of paper and such that a stop time of the moving member is variable based on the size of paper input by a user during movement of the moving member.
A control method of a paper feeder comprising a first paper loader placed in a paper feeder housing of an image forming apparatus to load paper to be fed into the image forming apparatus, a second paper loader placed in the paper feeder housing to load paper to be fed into the first paper loader, and a moving member to move the paper loaded on the second paper loader to the first paper loader, the control method comprising:
- receiving a paper size input by a user;
- moving the moving member to move the paper loaded on the second paper loader to the first paper loader if the first paper loader is out of paper;
- and
- stopping the moving member at a stop time variably set based on the received paper size.
An image forming apparatus comprising:
- a paper feeder housing;
- a first paper loader placed in the paper feeder housing to load paper to be fed into an image forming unit;
- a second paper loader placed in the paper feeder housing to load paper to be fed into the first paper loader;
- a movement unit having a moving member to move the paper loaded on the second paper loader to the first paper loader;
- an input unit to receive a paper size from a user;
- an image forming control unit to control the image forming apparatus and to transmit the paper size input via the input unit;
- and
- a controller to control the movement unit such that the moving member is moved to move the paper loaded on the second paper loader to the first paper loader if the first paper loader is out of paper and such that a stop time of the moving member is variable based on the size of paper transmitted from the image forming control unit during movement of the moving member.
A paper feeder comprising:
- first and second paper loaders to load paper thereon;
- a movement unit having a moving member to move the paper loaded on the second paper loader to the first paper loader;
- and
- a controller to control the moving member to move the paper loaded on the second paper loader to the first paper loader if the first paper loader is out of paper and to vary a movement distance of the moving member based on the size of paper input by a user during movement of the moving member.
A control method of a paper feeder to feed paper to an image forming apparatus, the control method comprising:
- receiving a paper size input by a user;
- moving a moving member to move the paper loaded on a paper loader to another paper loader if the paper loader is out of paper;
- and
- stopping the moving member at a stop time variably set based on the received paper size.
