d blocked even after normal purging, then try the powerful purging (“P” switch in
purging board has to be kept pressed for few seconds and then required color switch has to be pressed).
Head Blotting
Head blotting refers to the process in which the head surface area is cleaned with the help of tissue paper
or cloth. Blotting removes ink drops adhering to the Print Head nozzle surface. Gently touch with a clean
recommended head cleaning tissue on the head’s nozzle plate. One should make sure that the tiss
ue is
clean, soft, and also does not have any chemicals on it.
