The print results of the test pattern correspond to, from left to right, [Black (K1)], [Black (K2)],

heads] and [Flush Print-heads] functions in [Maintenance]. Text, such as K1, K2, Y1, C, and M1,
are printed on the print results of the test pattern.
For example, if a print result indicates that the test pattern of K1 is not firing, select [Black (K1)] for
[Clean Print-heads] or [Flush Print-heads] to reactivate the nozzle.
