Abstract

A printing apparatus includes a conveyance unit configured to be able to convey a roll sheet that is wound in a rolled shape and a cut sheet that is not wound in a rolled shape to a printing unit configured to print an image, a receiving unit detachably attached to the apparatus, the receiving unit being configured to receive the cut sheet onto which printing has been performed by the printing unit; a detection unit configured to detect whether the receiving unit is attached to the apparatus; and a holding unit configured to, in a case where the detection unit detects that the receiving unit is not attached to the apparatus, nip to hold the cut sheet onto which printing has been performed by the printing unit.

First claim

What is claimed is:

1. A multifunction printing apparatus, having a printing function and a scanner function, and comprising:
a mounting unit onto which a roll sheet that is wound in a rolled shape is mounted;
a stacking unit onto which a plurality of cut sheets that are not wound in a rolled shape are stacked;
a first pair of rollers configured to convey one of the roll sheet and a cut sheet in a conveyance direction to a printing unit configured to print an image by ejecting a liquid; and
a second pair of rollers provided downstream of the printing unit in the conveyance direction, and configured to convey one of the roll sheet and the cut sheet printed by the printing unit, wherein
the second pair of rollers holds the cut sheet, after completion of printing, while not conveying the cut sheet, and
a placement unit detachably attached to the multifunction printing apparatus, the placement unit being configured to place the cut sheets onto which printing has been performed by the printing unit.

2. The multifunction printing apparatus according to claim 1 , wherein, in a case in which the second pair of rollers holds the cut sheet while not conveying the cut sheet, the printing apparatus notifies a user that the cut sheet is held.

3. The multifunction printing apparatus according to claim 1 , further comprising:
a notification unit configured to notify a user that the cut sheet is held, in a case in which the second pair of rollers holds the cut sheet while not conveying the cut sheet.

4. The multifunction printing apparatus according to claim 1 , further comprising:
an operation unit configured to accept an operation input by a user.

5. The multifunction printing apparatus according to claim 1 , wherein, after completion of printing the cut sheet, the second pair of rollers nips the cut sheet in a state in which rotation of the second pair of rollers is stopped.

6. The multifunction printing apparatus according to claim 1 , further comprising:
a detection unit provided upstream of the second pair of rollers in the conveyance direction, the detection unit being configured to detect whether a sheet is nipped by the second pair of rollers whose rotation is stopped.

7. The multifunction printing apparatus according to claim 1 , further comprising:
a detection unit configured to detect whether the placement unit is attached to the printing apparatus.

8. The multifunction printing apparatus according to claim 1 , wherein the stacking unit is provided downstream of the mounting unit in the conveyance direction.

9. The multifunction printing apparatus according to claim 1 , wherein the roll sheet onto which printing has been performed by the printing unit is cut by a cutter.

10. The multifunction printing apparatus according to claim 9 , wherein the second pair of rollers holds the sheet cut by the cutter, after completion of printing, while not conveying the sheet.

11. The multifunction printing apparatus according to claim 1 , wherein the printing unit comprises an inkjet head that discharges ink.

12. The multifunction printing apparatus according to claim 1 , further comprising the printing unit.

13. The multifunction printing apparatus according to claim 1 , wherein the printing unit moves in a direction that intersects the conveyance direction.
