Abstract

The invention discloses a printer and a method for replacing a plate cylinder thereof. The plate cylinder (31) comprises a key groove (31b) and a registration mark (31c). The plate cylinder (31) is moved above or off from a printing unit (2) by a cart (5). The printing unit (2) comprises a plate cylinder hand-over mechanism (4), by which the plate cylinder (31) is handed over between two vertical frames (2a) and the cart (5), and a key groove position detection mechanism (60) for detecting the position of the key groove (31b). The cart (5) is provided with a plate cylinder rotation part (50) which enables the plate cylinder (31) to rotate around an axle center so that the registration mark (31c) can be positioned at a pre-determined position. The angle of the key groove (31b) and the registration mark (31c) around the axle center can be calculated by a control panel (7). Accordingly, the stopping time of the printer when the plate cylinder is replaced can be shortened, and the efficiency can be bettered.
