Whats the model of Goldbuddy you have.. Such as a platinum, world platinum, Gold buddy voice or voice +, etc?
Id refrain from cleaning the printhead any more, its just using ink at this point. Let me ask you this.. How long ago did that error begin to occur?
And also, have you tried unplugging the printer completely from power.. removing all ink tanks.. And then plugging it back in to see if you get a different error code?
