Abstract: A processor of a print device performs empty processing in a case where it has determined that it has received, from a remaining ink amount detector, a first signal that indicates that a remaining amount of an ink is not greater than a first prescribed amount. The processor also performs the empty processing in a case where it has not determined that it has received the first signal, but has determined that it has received a second signal. In the empty processing, the processor performs soak cleaning of a nozzle face and stores an empty soak standby flag in an EEPROM. The empty soak standby flag is a flag that prohibits the performing of a printing operation. Therefore, the print device is able to reduce the possibility that a decline in print quality will occur.

Abstract: A printing apparatus is capable of detecting the end of an ink ribbon and verifying normal mounting of a ribbon cassette. When a portion of ink ribbon sufficient for printing one character is transported, an actuator in the ribbon cassette is rotated by a predetermined amount. The rotating actuator turns on and off a switch. The number of times the switch status is changed is detected. Determining the switch ON-OFF count makes it possible to detect the ink ribbon end and to check for any abnormal winding operation of the ink ribbon. Thus a single switch arrangement permits detection of both the ink ribbon end and an abnormal ink ribbon winding operation that may occur.
