Printing apparatus, method of inspecting nozzles for abnormalities, and program |
摘要 |
A printing apparatus records a predetermined test pattern on printing paper, and reads the test pattern by means of a scanner. The scanner reads the test pattern at a resolution lower than the resolution of a recording head. This allows the automatic and fast reading of the test pattern. Additionally, the printing apparatus performs an interpolation process on read data, and judges whether there is an abnormality in nozzles or not, based on the read data subjected to the interpolation process. This reproduces the positions of and spacing between lines recorded on the printing paper with high accuracy to achieve the exact judgment as to whether there is an abnormality in the nozzles or not. Therefore, an inspection with a high degree of reliability is accomplished.
