New carts arrived today. Filled with Pieza Flush. Installed in printer. Did 3 power cleaning cycles with MK mode and 3 cycles in the PK mode. Did a nozzle check and everything looked fine. At this point a Message came on that the Maintenance cart was full. With the old carts I simply pulled it out, repacked with cotton balls and followed your instructions to reset. However with the new carts I did the same thing, but the message will not go away. In your HELPFUL INFORMATION I followed the instructions to reset the printer. Still the full message won’t go away. The printer is therefore shut down. Do I need a new waste tank rather than repacking the old one? or is there something else I’m failing to do.?
