If the free adjustment program fails or is not working, you can use the WIC Reset Utility . It is a free download that checks the waste ink counter.

Many versions are available for free, but some specialized versions may be sold.

Once this counter reaches its maximum threshold (100% capacity), the printer locks itself down as a safety measure. When this occurs, you will typically see alternating flashing red lights on the printer, and a computer error message stating: "A printer's ink pad is at the end of its service life.
