Dana, Walker, et al
I just installed a new MK ultra HD cart into my 3880. Printed a number of pages using the flush tiff through QTR calibration mode and everything was fine. Did a nozzle check and saw there was two spots that needed unclogging so used the automatic nozzle check. Immediately there was a very loud clicking noise every time the head passed - it finished the cleaning with a “cleaning error”. I then ran another regular nozzle check and each pass gave a very loud clicking noise and unfortunately now the lower 1/5 of the MK channel is clogged. I tried printing just a regular small print and the noise was on every head pass. My concern is what is that very loud clicking sound - any ideas?
Please any help would be appreciated.
