APPARATUS AND CONVEYANCE METHOD - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240101379 titled 'APPARATUS AND CONVEYANCE METHOD
Simplified Explanation
The patent application describes an apparatus for printing on a print medium, with a sensor to detect the print medium's position and a control unit to adjust the print medium's conveyance based on the sensor's readings.
- Conveyance roller: A roller that moves the print medium through the printing process.
- Print unit: Responsible for executing the printing on the print medium.
- Platen: Supports the print medium and faces the print unit during printing.
- Sensor: Emits and detects light to determine the position of the print medium.
- Control unit: Adjusts the print medium's conveyance based on sensor readings before and after the light irradiation region.

Original Abstract Submitted
an apparatus comprising a conveyance roller configured to convey a print medium, a print unit configured to execute printing on the print medium, a platen arranged to face the print unit and configured to support the print medium, a sensor configured to emit light to the platen and detect light from the platen, and a control unit configured to execute first control of acquiring, as a first value, a detected value before the print medium reaches a light irradiation region of the sensor, and acquiring, as a second value, a detected value after the print medium is conveyed to include the light irradiation region, wherein the control unit further execute second control of correcting a conveyance amount of the print medium by the conveyance roller based on the first value and the second value.
