If the ink printer is planned to be out of use for 30 days, it is recommended to start the machine and supply ink for 1 to 2 hours within 7 days after the interval; if it is planned to be out of use for 2 to 6 months, the ink in the machine should be drained, and the entire ink path system should be cleaned using a dedicated cleaning agent; at the same time, keep the last cleaning agent in the machine and start the machine to run for 2 hours every month.
