20130044151METHOD OF CONTROLLING A PRINTING DEVICE, AND A PRINTING DEVICE - A control method that conveys a recording medium fed from a first conveyance unit a specific number of paper feed steps after the leading end is detected by a first detection unit, and stops conveyance after conveying the leading end of the recording medium passed the second conveyance unit, second detection unit, and print unit to an initial printing position has a reference distance acquisition step that gets a reference number of conveyance steps equal to the distance between the second detection unit and the initial printing position in the specific number of conveyance steps; an actual step count measurement step that measures an actual number of steps the recording medium is conveyed during actual conveyance from detection of the leading end by the second detection unit until conveyance stops; and an evaluation step that determines if paper feed error occurred when conveying the recording medium.02-21-2013
20130044152INK JET PRINTING APPARATUS AND CONTROL METHOD THEREOF - When it is decided that the PE sensor installed upstream of the conveying roller has detected paper, the motor driving the recovery operation is stopped. This prevents paper jamming that may be caused by the reverse rotation of the motor during the recovery operation. That is, when print paper happens to remain on a conveying path for some reason, at a position where it can be driven simultaneously by both of the intermediate and the conveying rollers, the activation of the recovery operation, which is powered by the same motor that drives these rollers, can result in paper jamming because the recovery operation causes the conveying roller to rotate in a direction reverse to that of the intermediate roller. The paper jamming can, however, be prevented by stopping the conveying of the paper before it reaches a position where it is driven by the two rollers at the same time.02-21-2013
