2232c waste toner pipe clogged

[ash_572]

this only goes out to the yellow and cyan waste tunnel. toner is builing up in the pipes causing it to overfill the pipe and spill all over the back of the machine just at rear end of the transfer unit. and then eventually the cyan, yellow and sumtimes the magenta pcu seize up causing an sc 440-02. ive cleaned up the pipes and replaced pcus and few weeks after cloggs up again. the coil in the waste pipe (cyan and yellow) had snapped leaving it with only half coil. toner pumps were replaced and the fault came back in.

had this also one time, you'll need to replace the coils and the tunnels. Its a pain in the ass job
