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.
