On the printer's LCD panel- push the Menu button, then select Printer Setup (push right arrow/Menu button to select), scroll down to Auto Cleaning and push the right arrow to select, then select *OFF.
I have the auto cleaning cycle and auto nozzle checks disabled on all our printers, and they are all working very well with both ConeColor and Piezography inks.
The printers are programmed to keep some ink flowing to help avoid the print head from drying out, so some amount of regular cleaning is good for the health of the machine, and I expect uses less ink to maintain the printer than you would have to use doing cleaning cycles if the print head did dry out and you were fighting with clogging caused by dried ink in the print head.
I hope this answers your question.
Best regards and happy printing~ Dana
