Fuser clean-up purge sheets system for duplex reproduction apparatus

An improved method of cleaning imaging material from a fuser of a copy reproducing apparatus in a fuser cleaning purge cycle after an inadvertent interruption of the operation of said reproducing apparatus in which said fuser was potentially contaminated with imaging material from a copy sheet being fused, wherein said reproducing apparatus has an alternative duplex copying path, comprising:

• automatically sequentially feeding a preset limited number of preexisting conventional clean copy sheets in said copy reproducing apparatus through said fuser to function as fuser cleaning sheets to remove said potentially contaminating imaging material from said fuser,
• then feeding said same fuser cleaning sheets through said alternative duplex copying path of said reproducing apparatus back to and through said fuser a second time, with sheet inversion, so that these fuser cleaning sheets are inverted before said feeding through said fuser said second time,
• and then purging said same fuser cleaning sheets, to complete said fuser cleaning purge cycle;
• wherein said preset limited number of preexisting conventional clean copy sheets used as fuser cleaning sheets in said fuser cleaning purge cycle is four or less sheets;
• wherein said fuser has a fuser roll, and every area of the circumference of the fuser roll is contacted by said fuser cleaning sheets a minimum of four times during said fuser cleaning purge cycle;
• and
• wherein said fuser cleaning purge cycle is automatically initiated in response to sensing that a copy sheet was stopped in said fuser during said interruption of the operation of said reproducing apparatus.
