CONTROL METHOD OF A PRINTING DEVICE, AND PRINTING DEVICE

摘要

A printer that conveys label paper or black mark paper executes an appropriate process when conveying paper that has been spliced. While conveying label paper or black mark paper by the conveyance unit 42, the inkjet printer 5 calculates the interval at which the labels or marks are disposed based on detecting the label edges or marks by a sensor disposed to the conveyance path. An error is detected if the calculated interval is shorter than a specified length. If the calculated interval is longer than the specified length, the calculated interval is compared with the previously calculated interval. If the previously calculated interval is the same as the specified length, an error is not detected. If the previously calculated interval is longer than the specified length, an error is detected.

主权项

1. A control method of a printing device having a conveyance roller that conveys paper having detected parts at a specific interval in a conveyance direction, and a printhead that prints on the paper conveyed by the conveyance roller, comprising:
detecting the detected parts of the paper and calculating the interval between the detected parts while the paper is conveyed by the conveyance roller; detecting an error and executing an error handling process when an interval shorter than a specified length is calculated; comparing the previously calculated interval with the specified length when the calculated interval is longer than the specified length; not determining an error occurred when the previously calculated interval is the same as the specified length; and determining an error occurred and executing an error handling process when the previously calculated interval is longer than the specified length.
