Abstract
There is provided an image forming apparatus in which a waiting time is small and the throughput is not degraded. Therefore it is determined whether or not a delay accumulation operation is necessary at the time of performing a cap closing operation or a wiping operation. If necessary, the delay accumulation operation is performed.
Claims4
An image forming apparatus comprising:
- a print head for performing a print on a print medium;
- a sheet discharge unit configured to discharge the print medium to a sheet discharge tray with rotation of a sheet discharge roller;
- a recovery unit configured to perform a recovery operation of the print head;
- a delay accumulation mechanism for accumulating a delay amount by a delay accumulation operation with a backward rotation of the sheet discharge roller;
- and
- a determining unit configured to determine whether the delay accumulation operation is performed, wherein in the delay accumulation operation the sheet discharge tray is opened by rotating the sheet discharge roller in a forward direction exceeding the delay amount accumulated in the delay accumulation mechanism,
- wherein in a case where the determining unit determines that the delay accumulation operation is performed, the delay accumulation operation is performed at the time the recovery unit performs the recovery operation.
