Re: Epson r340 Printhead removal

Since people read experiences others have and use them as a guide, I just want to add a caveat.

Household ammonia can be between 5 and 10% ammonia in water solution. Window cleaners are usually about 1% ammonia. A 50/50 mixture of water and ammonia (assuming that's household concentration) is between 2.5 and 5% ammonia. This is probably higher than you would wish to use in most cases, as the Epson heads are vulnerable to corrosive liquids at that concentration.

A safer concentration is about 1-2%, especially is you will be leaving things to soak with it.

I used Davy's idea of unplugging during startup to free up the printer head assembly. I took a paper towel and soaked it in 50/50 ammonia and water and layed it down and moves the printhead manually across it several times, them left it sit on the towel for 15 minutes. I just printed as pretty a photo as this thing is capable of, so thanks all. BTW, I'm using a CIS for this and I wonder if I'm going to have trouble as a result.
