This certainly sounds interesting, and my HP printer has been acting up. But I'm curious now about head cleaning. I had an Epson printer back some years ago, and although it made nice prints when it worked, it used huge amounts of ink cleaning its heads, often requiring 6 or 8 cleaning cycles before it would make a print, and eventually clogging completely, with apparently no way to fix it other than sending it back to Epson. I got an HP that replaced its jets with every ink change, and worked great, but it broke. The next HP has been less satisfactory, doing cleaning cycles often when it starts, but at least it allows one to take the carriage out and wash it when it clogs. Has Epson improved here? I like the idea of not having to replace ink cartridges so often, but it's pointless if the printer stops working anyway.
I've heard of others in the past having similar problems with Epsons: great if you do lots of photos, but terrible if you do only occasional ones.
