Abstract
An image forming apparatus includes a platen on which an original is to be placed, a feeder configured to feed an original placed on a tray, a sensor configured to detect a sheet on the tray, a lamp provided to the feeder, a reader configured to read the original placed on the platen and to read the original conveyed by the feeder, an image forming unit configured to form an image on a sheet, and a controller. The controller is configured to control the image forming unit to form a test image on a sheet, control the reader to read the test image formed on the sheet placed on the platen, control a density of the image to be formed by the image forming unit based on a reading result of the test image.
Claims5
An image forming apparatus, comprising:
- a platen on which an original is to be placed;
- a feeder configured to feed an original placed on a tray;
- a sensor configured to detect a sheet on the tray;
- a lamp provided for the feeder, and configured to emit light when the sensor detects a sheet;
- a reader configured to read the original placed on the platen and to read the original conveyed by the feeder;
- an image forming unit configured to form an image on a sheet;
- and
- a controller configured to:
- control the image forming unit to form a test image on a sheet;
- control the reader to read the test image formed on the sheet fed by the feeder;
- and
- control the density of the image to be formed by the image forming unit based on a reading result of the test image, the lamp being turned on before the sheet on which the test image is formed is detected by the sensor,
- wherein the controller is configured to control, in a case in which the test image is formed by the image forming unit, the lamp to emit light before the sheet on which the test image is formed is detected by the sensor, and
- wherein a lighting pattern of the lamp in a case in which the test image is formed by the image forming unit is different from a lighting pattern of the lamp in a case in which the original is placed on the tray.
