Ink stack conservation

(1)Clean the waste ink on the ink stack platform regularly to keep the ink stack clean.

(2)Regularly drip cleaning fluid into the ink cap to prevent the waste ink tube from being blocked by waste ink for a long time.

(3)Regularly clean the rubber ring on the top of the ink cap with a cleaning fluid to prevent the rubber from hardening due to the use of solid waste ink for a long time, which will affect the ink absorption effect.
