| Re: How I fixed the \"clog from [censored]\" in an Epson 2200 An update to my original post.
Although I was able to clear the print head clogs using the cleaning fluid mentioned, I was not able to maintain a clog-free status for very long. I won't detail my journey of becoming intimately familiar with the internal workings of the Epson 2200, but I will summarize what I learned, which is: Persistent nozzle clogging is a SYMPTOM of something ELSE being wrong with the printer!
That "something else" is often a clogged purge tube (the tube that runs from the head cleaning station to the vacuum pump), or perhaps a broken/clogged vacuum pump. You can determine if this is the problem by moving the print heads away from the cleaning station. If there is enough ink there that it is pooling up, you have a vacuum problem. The print heads are basically swimming in excess ink and that is what keeps clogging them up. When it gets worse you will get brown stains on the leading edge of your prints, and nozzle checks will give muddy colors and smears in addition to the usual gaps. When it gets REALLY bad, you get ink splatters on your prints!
Lack of vacuum also means cleaning cycles are not doing anything good, for it is the vacuum applied at the cleaning station, in conjunction with the ink being pumped through the print heads, that actually cleans the print heads! Without any vacuum, print head cleaning is doing more damage than good!
The question is how to fix this. In my case, I jostled the purge tube immediately under the cleaning station by lifting the cleaning station up ever so slightly (a few mm). I was trying to get a small screwdriver in far enough to tap the purge tube, but I actually didn't get that far because I could see as I moved the cleaning station up that all of the sudden the pooled ink disappeared! You must be very careful if you try this because the cleaning station is very fragile and if you damage it, it's game over.
Once the ink started flowing through the purge tube, everything immediately started working as it should and it has been flawless since then, over two dozen prints with no problem.
I will comment that the common wisdom to leave the printer on is actually NOT VERY WELL FOUNDED! Every time you turn the printer on a brief vacuum cycle is applied to the print heads and this helps keep things in condition. I suspect those that have this belief use their printers a lot - and that is the BEST prescription for avoiding problems!
