Liquid ejection apparatus including curl reduction device, curl reduction method executed in the apparatus, and storage medium used for the apparatus

摘要

A liquid ejection apparatus includes: (a) a storage device for storing an image data set representing a plurality of images; (b) a liquid ejection head for performing an image formation on each recording medium; (c) a curl reduction device for reducing curl caused in each recording medium having the corresponding image formed thereon by the liquid ejection head; (d) an output tray for receiving each recording medium whose curl has been reduced by the curl reduction device, such that the received recording media are stacked on the output tray; and (e) a control device configured to control the curl reduction device, such that the curl caused in an earlier one of the recording media is reduced by a smaller degree than the curl caused in a later one of the recording media that has been subjected to the image formation later than the earlier one of the recording media.

主权项

1. A liquid ejection apparatus comprising:
a storage device configured to store therein an image data set representing a plurality of images that are to be formed on a plurality of recording media; a liquid ejection head configured to perform an image formation on each of the plurality of recording media, so as to form, on the recording media, the respective images represented by the image data set that is stored in said storage device; a curl reduction device configured to reduce curl caused in each of the recording media having a corresponding one of the images that has been formed thereon by said liquid ejection head; an output tray configured to receive therein each of the recording media whose curl has been reduced by said curl reduction device, such that the received recording media are stacked on said output tray; and a control device configured to control said curl reduction device, such that the curl caused in an earlier one of the recording media is reduced by a smaller degree than the curl caused in a later one of the recording media that has been subjected to the image formation later than said earlier one of the recording media, wherein said control device is configured to determine a waiting time for which each of the recording media is caused to stay in said curl reduction device, the waiting time for which said earlier one of the recording media is caused to stay in said curl reduction device being shorter than the waiting time for which said later one of the recording media is caused to stay in said curl reduction device, and wherein said control device is configured to control said curl reduction device such that said curl reduction device is caused to reduce the curl of each of the recording media by causing each of the recording media to stay in said curl reduction device for the waiting time.
