hi all i sign up here specially to seek help on my new printer and to discover more about fixing our own printers................ recently i purchased mp160 canon printer to replace my spoiled i255 canon printer.My i255 also had that waste ink tank problem and little did i know it was the programming part and not the hard ware part that will solve the problem....in the midst of trouble shooting the waste ink tank problem on the i255,i accidently spoiled my i255 printhead. Just trying to be self prepared here, in case my mp160 printer has this "waste ink tank almost full"problem in years to come, then wat should i do to reset it? many thanks for answers and comments.
