发明名称 Printer and control method for a printer
摘要 A carriage 11 carrying a printhead 7 moves on a transverse axis X by a carriage moving mechanism 15, and is detected by a first sensor 18 at a standby position 11B at one end of the range of movement. When the carriage 11 is at the opposing position 11A, the printhead 7 and head frame 12 are moved vertically by the head moving mechanism 17, and are detected at the up position 12A by the second sensor 19. When the position of the printhead 7 and carriage 11 are unknown, the control unit 1a of the printer 1 executes a recovery process that moves the carriage 11 to the opposing position 11A side, detects when the carriage 11 becomes locked at the opposing position 11A, and determines the position of the carriage 11.

主权项 1. A printer comprising: a printhead; a platen; a carriage that supports the printhead; a carriage moving mechanism configured to move the carriage in a first direction between an opposing position and a standby position, the opposing position being where the printhead is opposite the platen, and the standby position being where the printhead is not opposite the platen; a head moving mechanism configured to move the printhead in a second direction between a first head position and a second head position when the carriage is at the opposing position, the second direction crossing the first direction, the first head position being where a gap between the printhead and the platen is a first distance, and the second head position being where a gap between the printhead and the platen is a second distance that is shorter than the first distance; a second sensor configured to detect the printhead and disposed at a position at which movement of the printhead by the head moving mechanism is changed to movement of the carriage by the carriage moving mechanism; a first sensor disposed to a first detection position in a range where the carriage moving mechanism moves the carriage, and configured to detect the carriage; and a control unit configured to control movement of the printhead and the carriage based on a signal of the first sensor and a signal of the second sensor; wherein the second sensor is disposed to a second detection position in a range where the head moving mechanism moves the printhead, and configured to detect the printhead, the first detection position and the second detection position are different; the first detection position is the standby position; the second detection position is the first head position; and the control unit is configured to change movement of the carriage by the carriage moving mechanism and movement of the printhead by the head moving mechanism, when the printhead is at the second detection position and the carriage is at the opposing position.
