Abstract
The roll paper printer of the subject invention has a control to detect failure of a paper detector in accordance with a method for detecting such failure. The printeris constructed so that the paper transportation path is open when the coverto the roll paper compartmentis open and includes a paper detectorand a control unitto determine if the paper detectoris faulty. A failure warning is provided by a warning indicator(S) to indicate failure of the paper detectorwhen the coverhas been open continuously for at least a first set time (S) and the output state of the paper detectorhas not changed even once to a no-paper state within the first set time. Preferably, the printing operation of the printeris disabled upon determining that the paper detectoris faulty to permit replacement of the paper detector. Problems attributable to paper detector failure, such as soiling the platen with ink can thus be prevented.
