It should HELP to remedy your situation. Since you've already introduced air into the internal system, it may take a while to get it out even after the carts are purged.
I left the printer for 24 hours and attempted a 'regular' cleaning. Halfway through the process my 3800 indicates that my Ink Maintenance tank is full. So, instead of dealing with re-using the exisitng one and filling it with tissue, I ran out and bought a new one. I had to turn the printer off because it was hung up. BUT I had to turn it off during the stall in the cleaning process in order to reset the Maintenance Tank. So I did that and followed the instructions provided to me for resetting the tank. BUT, after releasing the carts as per the instructions, I pulled each one out and primed them as per the excellent video on the 'inkjetcarts' website. I was going to do that anyway if the cleaning process didn't work.
After going through the whole process, at the very end, after installing the lid cover key, I got a message telling me the 'Ink Maintenance Catridge Is Nearly Full'. I attempted the procedure seven times and got the same message. So I gave up not sure where to go.
BTW I have been in touch with customer service and, lo and behold, they've added on their website instructions page to prime the carts prior to the initial install! They informed me they did this after I brought this up to them yesterday. But, they do not provide instructions on how to do this.
After talking to customer service (very helpful BTW, I must commend them) I was finally able to get everything working 100%. There is no doubt that priming the carts prior to use is the most important step. I also want to say that the inkjetcarts videos were a great resource. I've made at least 20-8.5x11's since and my prints look wonderful. The inks match the Epson OEM's very, very close. There is slightly more gloss differential (barely) but not enough to warrant not being able to sell my prints.
Thanks again for the help, there is no way I would have been able to figure this out on my own.
Regarding the 4880 vs. 3800, I can't really say. I did own a 4800 and took a huge loss reselling it due to constant clogging problems. I bought the 3800 and the quality was the exact same, with zero clogging issues with the OEM inks.
thanks for your feed-back. I myself have experience your problem before and therefore it is so important to prime the cartridge prior before installation. I hope Inkrepublic.com will rewrite their instructions to include the priming procedure before installing the cartridges. Because too much cleaning cycles will push so much air in the system, the problem will look worse, but it is not.
