The invention relates to a printer nozzle protection mechanism and method.The nozzle protection mechanism comprises supports on the two sides, a probe piece fixing front pressing plate, a correlation sensor and a plurality of probe pieces, the transmitting end and the receiving end of the correlation sensor are installed on the supports on the two sides respectively, and the probe pieces are arranged between the supports on the two sides through the probe piece fixing front pressing plate; through holes for light emitted by the correlation sensor to penetrate through are formed in the probing pieces, the probing pieces are elastic pieces, and when the probing pieces touch obstacles, the probing pieces can elastically deform, so that the through holes formed in the probing pieces do not right correspond to the through holes in other probing pieces which do not touch the obstacles. When any probe sheet touches an obstacle, the probe sheet can elastically deform so as to shield light emitted by the correlation s
