I have been meaning to respond to this since you posted it, but haven't had a chance until now.
Thank you for your input, and we have also received successful reports from customers who have done this one their own. It's great to resolve a stubborn clog/blockage, and get the channel printing fully again, but I have a few concerns I'd like to explain.
If you have ink installed in a pro model printer (with internal ink lines and dampers between the cartridges and print head), and experience a stubborn blockage that isn't fixed by following our manual cleaning procedures or cleaning thru the Epson utilities, flushing the channel is often the next thing to try, followed by replacement of the dampers and other parts. Due to the absence of power clean cycles with the R3000 printer model, cleaning is a little different than other models that do have this cleaning feature. Desktop printer models that don't have ink lines and dampers that connect to the print head, can often be cleaned and saved from serious clogging using our PiezoFlush solution and print head cleaning kit. The print head cleaning kit can also be used to flush a pro model print head- but the dampers and ink lines should be disconnected first, and cleaning kit connected/used directly on the print head channels.
Dampers have very thin plastic membranes, which are fragile and necessary for proper function. If a damper membrane is damaged, it will effect ink flow and must be replaced (can not be repaired, and won't work if broken). Excessive pressure can damage a damper, or blow out a connection seal somewhere in the internal ink system. Even if you don't cause physical damage to the printer, if you inject PiezoFlush into the ink line of a printer with ink installed to try clearing a clog, then reinstall the cartridge and discover the clog is freed/fixed- then that is awesome, but you need to keep in mind that you now have a few ml of pink PiezoFlush mixed with ink in the line, which will make it's way to the print head and effect your output. There's no way of knowing exactly when the pink PiezoFlush will make it's way to the print head, or how long it will take to be fully out, so I would suggest wasting some ink and doing a few power clean cycles or printing pure sheets of that channel to ensure pure ink for accurate/consistent output.
Just wanted to share the risks involved. We always have a long to do list and have a lot going on, but a big and important item on our list is to make MANY more videos, including more extensive printer cleaning and possibly even some basic repair- so be sure to keep an eye on our newsletters, forum and website for lots of new and cool things on the way!
Best regards and happy printing~ Dana
