Abstract

A medium processing apparatus includes an intermediate stacker on which media recorded by a recording apparatus are stacked, the recording apparatus including a liquid ejection head which performs recording by ejecting liquid to media and a maintenance apparatus which performs maintenance of the liquid ejection head, and a processor which executes a process on the media received by the intermediate stacker. The medium processing apparatus executes the process after a medium which is last recorded before the maintenance is stacked on the intermediate stacker.

First claim

What is claimed is:

1. A method for controlling a medium processing apparatus including a medium stacking section on which media recorded by a recording apparatus are stacked, the recording apparatus including a liquid ejection head which performs recording by ejecting liquid to a medium and a maintenance section which executes a maintenance operation on the liquid ejection head and a post-processor which executes a post- process on the media received by the medium stacking section, the method comprising:
determining a last medium that is to be recorded on by the liquid ejection head prior to starting the maintenance operation on the liquid ejection head;
stopping recording by the liquid ejection head prior to starting the maintenance operation on the liquid ejection head;
transporting the last medium to the medium stacking section during a time period where the recording by the liquid ejection head is stopped;
stacking the last medium, which is last recorded before the maintenance operation is performed, on the medium stacking section, and
executing the post-process.

2. A method for controlling a recording system including
a recording apparatus including
a liquid ejection head which performs recording by ejecting liquid to a medium and
a maintenance section which executes a maintenance operation on the liquid ejection head and
a medium processing apparatus including
a medium stacking section on which media recorded by the recording apparatus are stacked and

a post-processor which executes a post-process on the media received by the medium stacking section, the method comprising:
determining a last medium that is to be recorded on by the liquid ejection head prior to starting the maintenance operation on the liquid ejection head;
stopping recording by the liquid ejection head prior to starting the maintenance operation on the liquid ejection head;
transporting the last medium to the medium stacking section during a time period where the recording by the liquid ejection head is stopped;
stacking the last medium, which is last recorded before the maintenance operation is performed, on the medium stacking section, and
executing the post-process.

3. The method for controlling the recording system according to claim 2 , wherein the maintenance operation is started before the last medium reaches the medium stacking section.

4. The method for controlling the recording system according to claim 3 , wherein the maintenance operation is started in response to stopping recording by the liquid ejection head on media included in targets of the post-process when a processing interval time, which is an interval of the post-process, shorter than a predetermined maintenance interval time, which is an interval of execution of the maintenance operation.

5. A post-processing apparatus comprising:
a medium stacking section on which media recorded by a recording apparatus are stacked, the recording apparatus including a liquid ejection head which performs recording by ejecting liquid to a medium and a maintenance section which executes a maintenance operation on the liquid ejection head;
a post-processor configured to execute a post-process on the media received by the medium stacking section; and
controller configured to control operations of the post-processor, wherein the controller performs the following:
determines a last medium that is to be recorded on by the liquid ejection head prior to starting the maintenance operation on the liquid ejection head;
stops recording by the liquid ejection head prior to starting the maintenance operation on the liquid ejection head;
transports the last medium to the medium stacking section during a time period where the recording by the liquid ejection head is stopped; and
executes the post-process after the last medium is stacked on the stacking section.
