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 and a platen; a carriage that supports the printhead movably in the direction increasing or decreasing the gap between the printhead and the platen; a carriage moving mechanism configured to move the carriage to an opposing position where the printhead is opposite the platen, and a standby position where the printhead is not opposite the platen; a head moving mechanism configured to move the printhead between a first head position where the gap between the printhead and platen is a first distance, and a second head position where said gap is a second distance that is shorter than the first distance, when the carriage is at the opposing position; and a sensor configured to detect the printhead and is disposed to the position of change between movement of the printhead by the head moving mechanism and movement of the carriage by the carriage moving mechanism.
