*1: As the waste ink counter is reset when the logic board ass’y is replaced, also replace the 4-item set of the

drain pack ass’y (QL2 -0194) and the 3 ink absorbers (QC1-1210/1211/1212) at the same time.

*2: The waste ink absorber full error occurs when either the main waste ink absorber (drain pack ass’y) or the

borderless printing waste ink absorber (ink absorber) becomes full. For this reason, all the waste ink absorbers should be replaced at the same time.

Error Solution

Replace the print unit.
