SHEET DETERMINING METHOD AND PRINTING APPARATUS |
| 摘要 |
There is provided a method that can determine the type or surface condition of a sheet with high accuracy even when performance of an optical sensor is degraded by ink mists or the like. Specifically at the time of detecting light from a sheet with a sensor to make a determination on the sheet, at least two detection values are obtained by changing a relation between the sensor and the sheet, and the type or surface condition of the sheet is determined by using the at least two detection values obtained. |
