Cutter routine troubleshooting a photoelectric protection Tianjin production of full paper cutter malfunction, after emergency treatment machines still work, but because there is no protection detection, very worried about the safety of the operator, resulting in inefficiency . Remove the circuit board, visual inspection, found that the substrate discoloration around the power bridge rectifiers, bridge rectifiers judge has burnt out, replace bridge rectifiers powered test, still no response.

The operator of the circuit board attached to the machine, and in accordance with normal operating procedures, checking optical protection function is working, hands over the photocell, Dongguan label printing production, falling knife immediately stopped, tried several times, were normal . Failure thus excluded. In our lives applications stickers printed products, some of which are needed to paste stickers, then for self-adhesive stickers printed products in excess of that dirt imagine how we should carry out its dirty dirty deal with it?
