Mine were swelling also, of course it wasn't Mutoh's fault. We bought a new one replaced it, not more than a couple of days later we started having problems again, swelling up, etc... had to take it apart and put it inside a phone book to dry out until I could get one of the new ones. Finally got the one with the mesh screen, only waited about eight weeks. Seems to be working okay now. Funny how there wasn't a problem but they found a fix??? The ink problem is really getting to me, I spent most the day on the phone with Mutoh Friday. After much discussion they will be replacing my unopened ink cartridges, I don't even want to use them as recently almost every one I have used the plastic thing has de-laminated from the bag so the machine does not know the cartridge is empty. Hopefully the new ones will not do this. Mutoh wants me to send the faulty cartridges to them. I'm not real willing to do that and told them so. They don't understand saying that they only want to help me. My thinking is if I send them in then they can pretend like it never happened. I think they should look at the ones I have returned to Fellers and also to one of their reps when I attended Sign Plus and Banners open house two weekends ago. Also funny thing on my cartridges, one has a double label, if you peel the label up you can see there was a different p/n number on it originally and another one the manufacture date has had a sticker put over it with another date on it. Just a thought but since there aren't that many of us Mutoh Falcon Outdoor users anymore do they have alot of old ink that they are re-labeling just to get rid of it and putting there problems onto us? I asked Mutoh the same thing and they said they can't imagine why there are double labels on mine, that's why they want to see them. The people I am speaking with seem very nice, but somebody there knows what's going on and just won't fess up. When I first called Mutoh on the delamination problem I was told that we were inserting the cartridges too roughly. Imagine that, we've had this printer for six years and never had this problem but now within the last year we all of a sudden are being too rough? They then said they aren't blaming us just that accidents happen especially when you are in a hurry. I love how they blame us! Like we don't know how to change a cartridge after six years! Now as of Friday the story has changed and Mutoh said there must be something broken in the cartridge support assembly. Mutoh told us to take the inks out and then the back off and they were absolutely sure there was something broken back there that was breaking the cartridges. Well we did, there's nothing in there that can make those tabs break. Nice try but not going to work, they need to figure out what is wrong with their cartridges. Nice to know someone else is having the problems with the cartridges also since they said I was absolutely the only one!
...and the cartridges are so expansive
