Hello,
Well, I tried an ink switch in service mode, and it went off well with no automatic clean and no clog, as verified by before and after nozzle patterns.
I also tried regular printing in service mode and found it to work as usual, except that it did not cut off the roll length codes before printing as it does in regular mode. It does seem to read them, and to print them correctly when the roll is removed. Also, there is no setting of paper type or length in service mode when loading.
I will use service mode for ink swaps and probably for a bunch of printing. This seems to be a good solution. I may not find out if my ANC is working or not, but maybe I don't need to know!
Thanks,
Michael
