we are do it yourselfers cannot tell you how much money we have saved over the years. the printer carriage you cannot remove it has no grey flipper so I seen on you tube someone had the top off of one to get to the carrage and cartiridge. but he didn't video how to get the fax/multip print loader off the top so you can actually see the carriage. thinking black carriage filter may be plugged as with a glove some crumbly ink came out. please advise. i love this printer just want to keep running it if I can GREAT MACHINE I think it may just need some TLC and small parts...Want to try before sending it in which I would not do given the repair costs more than a new one...please advise
