The clerks in the stores don’t wear their masks much, these days.
I’ve been trying to clean the print heads for the last hour and I’m still not getting very far. Only black and yellow are visible and those aren’t the colors I need.
I think I’ve run through the program six times. Unngh.
Try a spot of rubbing alcohol wipe over the print heads...works well on ball gel pen points that have sat around too long.
