Abstract
Conveyance of a sheet in an inkjet recording apparatus may be stopped under various conditions. In one example, a control device of the inkjet recording apparatus may stop conveyance on the sheet depending on the image to be formed in one or more portions of the sheet. Alternatively or additionally, conveyance may be stopped based on an amount of ink ejected or to be ejected onto a sheet, or portion thereof. The conveyance stoppage control may be used in conjunction with a corrugate mechanism in some arrangements.
Claims26
An inkjet recording apparatus, comprising:
- a first conveyor configured to convey a sheet in a conveyance direction;
- a support portion comprising a plurality of protrusions spaced apart from each other with respect to a width direction perpendicular to the conveyance direction, wherein the support portion is disposed downstream of the first conveyor with respect to the conveyance direction and configured to support the sheet from below;
- a recording portion disposed opposingly above the support portion and configured to record an image onto the sheet supported by the support portion based on print data by ejecting ink droplets from nozzles;
- a contact portion disposed between a pair of protrusions of the plurality of protrusions with respect to the width direction and in a manner that the contact portion faces the support portion;
- and
- a control device configured to:
- determine, based on the print data, a value related to an amount of ink needed to form an image, corresponding to the print data, on the sheet;
- determine whether to stop conveyance of the sheet, in a state where the sheet faces the contact portion, based on the value;
- and
- stop the conveyance of the sheet in response to determining that the conveyance of the sheet is to be stopped.

An inkjet recording apparatus, comprising:
- a conveyor configured to convey the sheet in a conveyance direction along the guide portion in a conveyance path;
- a support portion is disposed downstream of the conveyor with respect to the conveyance direction and configured to support from below the sheet being conveyed in the conveyance path;
- a recording portion disposed opposingly above the support portion and configured to record an image onto the sheet supported by the support portion based on print data by ejecting ink droplets from nozzles;
- a corrugate mechanism configured to form a corrugated shape in the sheet;
- and
- a control device configured to:
- determine, based on the print data, a value related to an amount of ink needed to form an image, corresponding to the print data, on the sheet;
- determine whether to stop conveyance of the sheet, in a state where the sheet faces the corrugate mechanism, based on the value;
- and
- stop the conveyance of the sheet in response to determining that the conveyance of the sheet is to be stopped.
