Abstract

A printing apparatus that includes a holding unit configured to hold a roll sheet performs supplying the sheet by rotating the roll sheet held by the holding unit; nipping and conveying the supplied sheet; performing printing on the conveyed sheet; detecting occurrence of a print medium jam of the sheet; and, if the printing apparatus has detected a print medium jam of the sheet, performing a control process of supplying the sheet in a state in which the conveying is stopped.

First claim

What is claimed is:

1 . A printing apparatus comprising:
a holding unit configured to rotatably hold a roll sheet; a conveyance roller configured to convey a sheet pulled out of the roll sheet in a first direction; a carriage configured to carry a printhead that discharges ink on the sheet conveyed by the conveyance roller; a cover configured to cover at least a part of the carriage and not cover the holding unit; and a display unit configured to display prompting for cutting a loop of the sheet that is formed between the holding unit and the carriage and that is formed outside of the cover, wherein the loop is convex upward.

2 . The printing apparatus according to claim 1 , wherein the display unit displays prompting for cutting the loop in a case in which a jam of the sheet has occurred.

3 . The printing apparatus according to claim 2 , further comprising:
a detecting unit configured to detect occurrence of the jam.

4 . The printing apparatus according to claim 2 , wherein the display unit displays a display item for being pressed by a user in a case in which the jam has occurred.

5 . The printing apparatus according to claim 2 , wherein the display unit displays the instruction prompting for cutting the loop in response to an operation by a user after the jam has occurred.

6 . The printing apparatus according to claim 5 , wherein the operation includes pressing a display item displayed on the display unit.

7 . The printing apparatus according to claim 1 , wherein the loop is formed upstream of the carriage with respect to the first direction.

8 . The printing apparatus according to claim 1 , wherein the loop is formed between the holding unit and the conveyance roller with respect to the first direction.

9 . The printing apparatus according to claim 1 , wherein the loop is formed by pulling out the sheet from the roll sheet held by the holding unit.

10 . The printing apparatus according to claim 1 , further comprising:
a cutter, arranged downstream of the carriage in the first direction, configured to cut the sheet.

11 . The printing apparatus according to claim 10 , wherein the cutter has an engaging part engaging with the carriage.

12 . The printing apparatus according to claim 11 , wherein the cutter moves in a second direction crossing the first direction by engaging the engaging part with the carriage.

13 . The printing apparatus according to claim 1 , wherein, in a case in which the carriage does not move normally, the display unit displays the prompting for cutting the loop.

14 . The printing apparatus according to claim 1 , wherein the holding unit is not covered with a cover.

15 . The printing apparatus according to claim 1 , wherein the printhead performs printing in a state in which the roll sheet held by the holding unit is not covered.

16 . The printing apparatus according to claim 1 , wherein the carriage mounts a tank configured to store ink to be supplied to the printhead.

17 . The printing apparatus according to claim 1 , wherein the conveyance roller further conveys a cut sheet.
