Hi Guys, working on Bizhub 500... 135,000 copies on meter, came up with c2803 -- TCR abnormality. Did trouble reset a number of times. Went into imaging process ran a TCR, fault still there. Added some toner to dev box, ran TCR again. Fault went away. Put the toner bottle motor under test, bottle turns ok. 300 copies later fault came back. Replaced starter, did TCR, no luck, Replaced ATDC sensor, did TCR, no luck, replaced print control board, no luck, gave the copier good vac and clean, Checked all the connections on the boards. at end of TCR run it comes up with "error 5" -- any help appreciated. Glad the weekend is here!
