Thanks, some good info here. Mine is the G6020 also. I understand not serviceable, but had some follow up questions. So mine is several years old and regularly used, but the black cartridge needed an ink flush, i.e. 2 cleaning and 2 deep cleanings wouldn't do the trick. So I went to the manual for 5200 code and the last item was an ink flush and it worked. Used quite a bit of ink, glad there is a reservoir. How many times (cleanings, ink flushes) can this happen before the reservoir is full? When full, is the printer trashed at that time? Thanks for any help.
