摘要:
An image reading device includes a reader, a transparent member, an opposing member, first and second conveyance rotators, and circuitry. The reader reads a sheet. The transparent member is disposed between the reader and the sheet. The opposing member is disposed facing the reader via the transparent member. The first conveyance rotator is disposed upstream from the reader in a conveyance direction of the sheet. The second conveyance rotator is disposed downstream from the reader in the conveyance direction. The circuitry cause the first conveyance rotator and the second conveyance rotator to convey a cleaning sheet at respective conveying speeds different from each other and bring the cleaning sheet into contact with at least one of the transparent member or the opposing member.
摘要:
An image reading device includes a sensor and circuitry. The sensor reads an image on a recording medium. The circuitry inspects the image and outputs an inspection result. The circuitry excludes an area of the recording medium as a first area from an area to be inspected, based on a type of the recording medium or a position of the recording medium with respect to a reading position at which the sensor reads the image, to determine a second area to be inspected. The circuitry outputs the inspection result based on the second area.
