METHOD AND APPARATUS FOR CONTROLLING EXPOSURE AND PREVENTING REVERSE LOAD IN A PRINTER OF AN ELECTROPHOTOGRAPHIC DEVELOPMENT SYSTEM

摘要

a) Method and apparatus for controlling exposure and preventing reverse charge in a printer of an electrophotographic developing system. BR/ b) A method characterized in that it comprises the various steps of starting the supply of a printing paper, starting a load block, a tracking detector (111) and a block of paper. exposing (105), and ascertaining whether the top of the paper reaches a transfer block (106) turning on the transfer block if the top of the paper reaches this transfer block; checking whether the registration detector (111) is turned off; if the registration detector is turned off, check if it is the moment when the bottom of the paper reaches this transfer block; and if it does, cut off the transfer block, perform the melting, and cut the load block.
