  • Patent number: 8783982
    Abstract: A media processing device and control method for a media processing device enable accurately setting and detecting the home position of a carriage without using a dedicated sensor. Scales 56, 62 having a plurality of wide slits 65 formed at equal intervals and a narrow slit 66 at one end 56A, 62A are disposed parallel to carriage shafts 53, 60. Carriage sensors 55, 61 scan the scales 56, 62 while the carriages 52, 58 move bidirectionally, and detect the wide slits 65 and the narrow slits 66. To initialize the carriages 52, 58, the carriages 52, 58 are moved specific distance L away from the one end 56A, 62A, and the carriages 52, 58 are then reversed and moved until the carriage sensors 55, 61 detect the narrow slits 66. The home position HP is set based on where the narrow slit 66 is detected.

  • Patent number: 8721020
    Abstract: The throughput of a serial printer is improved. A inkjet printer 100 has a print unit that prints on a print medium; a first transportation unit that conveys the print medium in the primary scanning direction; a second transportation unit that conveys the print unit in a secondary scanning direction substantially perpendicular to the primary scanning direction; and a control unit that controls the transportation operations of the first and second transportation units, so that the time required to move the print unit from the stop-printing position where the print unit finishes printing one print area to the start-printing position where transportation for printing the next print area starts is shortest. The control unit also determines a transportation range that may include the print unit going beyond the stop-printing position when the print unit prints the one print area.

  • Patent number: 8616794
    Abstract: In a printer that prints to continuous paper, starting to backfeed the recording paper for printing the next print job before the user cuts the previously printed page can be prevented. The printer prints while conveying recording paper delivered from fanfold paper through a transportation path, and after printing cuts the recording paper using a cutter disposed near the paper exit. When printing ends, the control unit positions the perforation at the trailing end of the printed page to a cutting position, and sets a tear-off state holding the recording paper where positioning was completed. When new print data is received while in the tear-off state, the recording paper transportation operation is prohibited and the tear-off state is continued until a preset delay time passes. When the delay time has passed, the recording paper is immediately fed back and indexed for the next print job.
