Abstract
An image forming apparatus includes a feeder having a tray and configured to convey a sheet, a reader including a platen, an image forming unit configured to form a test pattern, and a controller. The controller adjusts, based on a result of reading the sheet having the test pattern formed thereon, a quality of an image to be formed by the image forming unit. In a case where a sheet of a first type having the test pattern formed thereon is placed on the tray, the feeder conveys the sheet. In a case where a sheet of a second type having the test pattern formed thereon is placed on the tray, the controller is configured to display a notification representing that the sheet is not to be conveyed by the feeder.
Claims15
An image forming apparatus, comprising:
- a feeder including a tray, on which a sheet is to be placed, the feeder being configured to convey the sheet on the tray;
- a reader including a platen, on which a sheet is to be placed, the reader being configured to read the sheet on the platen, and to read the sheet conveyed by the feeder;
- an image forming unit configured to form a test pattern;
- a controller configured to:
- control the image forming unit to form the test pattern on a sheet;
- control the reader to read the sheet having the test pattern formed thereon;
- and
- control based on a result of reading the sheet having the test pattern formed thereon, a density of an image to be formed by the image forming unit;
- and
- a display,
- wherein the controller allows, in a case where a sheet of a first type having the test pattern formed thereon is placed on the platen, a first reading process in which the reader reads the sheet on the platen,
- wherein the controller allows, in a case where a sheet of the first type having the test pattern formed thereon is placed on the tray, a second reading process in which the feeder conveys the sheet on the tray so that the reader reads the sheet on the tray,
- wherein the controller allows, in a case where a sheet of a second type having the test pattern formed thereon is placed on the platen, the first reading process in which the reader reads the sheet on the platen,
- wherein the controller controls the display, in a case where a sheet of the second type having the test pattern formed thereon is placed on the tray, to display a screen for prompting the sheet on the tray to be placed on the platen on the display without allowing the second reading process, and
- wherein the first type is different from the second type.
An image forming apparatus, comprising:
- a feeder including a tray, on which a sheet is to be placed, the feeder being configured to convey the sheet on the tray;
- a reader including a platen, on which a sheet is to be placed, the reader being configured to read the sheet on the platen, and to read the sheet conveyed by the feeder;
- an image forming unit configured to form a test pattern;
- a controller configured to:
- control the image forming unit to form the test pattern on a sheet;
- control the reader to read the sheet having the test pattern formed thereon;
- and
- control, based on a result of reading the sheet having the test pattern formed thereon, a geometric characteristic of an image to be formed by the image forming unit;
- and
- a display,
- wherein the controller allows, in a case where a sheet of a first type having the test pattern formed thereon is placed on the platen, a first reading process in which the reader reads the sheet on the platen,
- wherein the controller allows, in a case where a sheet of the first type having the test pattern formed thereon is placed on the tray, a second reading process in which the feeder conveys the sheet on the tray so that the reader reads the sheet on the tray,
- wherein the controller allows, in a case where a sheet of a second type having the test pattern formed thereon is placed on the platen, the first reading process in which the reader reads the sheet on the platen,
- wherein the controller controls the display, in a case where a sheet of the second type having the test pattern formed thereon is placed on the tray, to display a screen for prompting the sheet on the tray to be placed on the platen on the display without allowing the second reading process, and
- wherein the first type is different from the second type.
