Cleaning the Printhead
If printing is faint, cleaning the Printhead may improve results.
Choose one of two Printhead cleaning modes ( Head Cleaning A or Head Cleaning B), depending on the problem to re-
solve.
• Head Cleaning A
Use this mode if printing is faint or contains foreign substances. This method of cleaning consumes the least amount of
ink.
It takes about three and a half minutes to complete.
• Head Cleaning B
Use this mode if no ink is ejected at all, or if Head Cleaning A does not solve the problem.
It takes about four minutes to complete.
