Image recording apparatus and controlling method for the same

1. An image recording apparatus which records an image by ejecting ink to a record medium fed from a feed mechanism while the record medium is being transported by a transportation belt, the apparatus comprising:

a recording head including a nozzle that ejects ink onto the record medium;

a restoration mechanism which is movable to a retracted position and to a restoration process position facing the recording head, wherein the restoration mechanism is loaded on the transportation belt when the restoration mechanism is located at the restoration process position;

a jam position detection unit for detecting a position of a stuck record medium when a record medium jam occurs; and

a restoration mechanism control unit for determining whether or not to move the restoration mechanism from the retracted position to the restoration process position based on the position of the stuck record medium when a request to operate the restoration mechanism is received while the record medium is jammed.

2. The image recording apparatus according to claim 1 , wherein when the stuck record medium is at a position at which the stuck record medium would contact the restoration mechanism while the restoration mechanism moves to the restoration process position, the restoration mechanism control unit determines to not move the restoration mechanism from the retracted position to the restoration process position.

3. The image recording apparatus according to claim 1 , wherein when the stuck record medium is positioned on the transportation belt, the restoration mechanism control unit determines to not move the restoration mechanism from the retracted position to the restoration process position.

4. The image recording apparatus according to claim 1 , wherein when the stuck record medium is stuck upstream from the feed mechanism in a transportation direction, the restoration mechanism control unit determines to move the restoration mechanism from the retracted position to the restoration process position.

5. The image recording apparatus according to claim 1 , wherein the request to operate the restoration mechanism includes at least one of a request to cause the image recording apparatus to switch over to a standby mode or low power consumption mode and a request to shut down the image recording apparatus.

6. The image recording apparatus according to claim 1 , wherein when the restoration mechanism is at the restoration process position, the restoration mechanism is at a position at which the restoration mechanism receives ink from the nozzle.

7. The image recording apparatus according to claim 1 , wherein the restoration mechanism comprises a wiping unit for wiping away ink adhering to the recording head.

8. The image recording apparatus according to claim 7 , wherein when the restoration mechanism moves to the restoration process position, the wiping unit wipes away ink on the recording head.

9. A control method for an image recording apparatus which records an image by ejecting ink to a record medium fed from a feed mechanism while the record medium is being transported by a transportation belt, wherein the image recording apparatus comprises a recording head including a nozzle that ejects ink onto the record medium, and a restoration mechanism which is movable to a retracted position and to a restoration process position facing the recording head, the method comprising:

detecting a position of a stuck record medium when a record medium jam occurs; and

when a request to operate the restoration mechanism is received while the record medium is jammed, determining whether or not to move the restoration mechanism from the retracted position to the restoration process position based on the position of the stuck record medium,

wherein the restoration mechanism is loaded on the transportation belt when the restoration mechanism is located at the restoration process position.

10. The control method according to claim 9 , wherein, when the stuck record medium is at a position at which the stuck record medium would contact the restoration mechanism while the restoration mechanism moves to the restoration process position, it is determined not to move the restoration mechanism from the retracted position to the restoration process position.

11. The control method according to claim 9 , wherein, when the stuck record medium is positioned on the transportation belt, it is determined not to move the restoration mechanism from the retracted position to the restoration process position.

12. The control method according to claim 9 , wherein, when the stuck record medium is stuck upstream from the feed mechanism in a transportation direction, it is determined to move the restoration mechanism from the retracted position to the restoration process position.
