I have a C6500 print engine which works just beautifully but recently I have had quite some hassles with it. After about 200 prints I get spoons-ful of toner falling onto the pages and smudges all over - then after a short while I get a sting of errors (mainly C4520). After many trials and checks I realised that the "toner remover assy" which slots onto the printing belt has a lot of spent toner in it and somehow it is not transported into the spent- toner bin. I removed the "toner remover assy" and cleaned it out and also tested the "worm srew drive" which is supposed to transport the spent toner out and all works fine.
Further I also removed the "gutter system" which is supposed to remove the spent tone to the bin to see if there are any blockages, and with some patience I managed it, cleaned it all and refitted the lot (on the inside of the machine). The problem is still there which makes me believe that perhaps the motor which drives the "spent toner gutter system" is perhaps not working well. I have a I/O test list with codes of various motors which I can switch on and off by means of different codes but cant seem to find the one for the Toner removal system.
The problem is really that the spent toner from the belt is not transported out of the machine properly and keeps on accumulating in the "removal assy" on the belt and then falls out onto the colour registration sensors and the works below - needless to say that this creating a lot of mess, not to mention the times I have to remove the entire Colour registration assy in order to clean it out as well as the sensors.
Maybe someone had a similar problem fixed ot knows of any idea to try and solve this. I have also photos of the parts in question. Sorry if I did not use the right names of the various parts - hope it is clear enough.
On the one photo the red circle shows the motor which I think is defective???, the blue outlines the horizontal "Gutter system" and the yellow the mess created each time after about 200 prints. The other pic is of the horizontal "gutter system"
Any help or suggestions are very welcome
