Abstract
A printer performs automatic calibration of a sheet-detection sensor by acquiring a measurement voltage and setting a threshold according to predetermined conditions. Sheet presence or absence may be determined based on voltage variation during optional sheet feeding. A registration flag may suppress repeated calibration. This configuration reduces user intervention and allows stable detection regardless of sheet type.
Claims9
A printer, comprising:
- a calibration module configured to execute calibration of setting a threshold value for a measurement voltage value of a sensor configured to detect whether a sheet is present or absent;
- and
- a condition determination module configured to determine whether a condition for executing the calibration is satisfied,
- wherein the calibration module is configured to acquire the measurement voltage value from the sensor when the condition determination module determines that the condition is satisfied, and set the threshold value based on the acquired measurement voltage value.

A printer control method, comprising:
- executing calibration of setting a threshold value for a measurement voltage value of a sensor configured to detect whether a sheet is present or absent;
- and
- determining whether a condition for executing the calibration is satisfied,
- wherein the executing of the calibration includes acquiring the measurement voltage value from the sensor when it is determined that the condition is satisfied in the determining, and setting the threshold value based on the acquired measurement voltage value.
