Hi everyone,
I am having an issue with my Epson R260 inkjet printer. I recently tried to print a document and discovered that cyan was not printing. The printer was inactive for roughly 3 weeks. I performed numerous head cleanings and nozzle checks and nothing seemed to solve the problem. The rest of the story is long and complicated but I contacted the merchant whom I bought this printer from and he informed me that the print head on the r260's are prone to "freezing" and that I should contact Epson to follow up on their warranty. Epson claims they are not responsible because I am using a continuous ink system. I personally believe the cyan ink I was sold contained sediment and the seller does not want to admit this. I have gone back and forth with these people and I have now decided to take matters into my own hands. My question is this:
I have removed the print head assembly which contains the 6 plastic nipples on one side with the print head on the reverse. There appears to be 3 screws connecting the print head to a small plastic base which is connected to a larger plastic housing. Where these two plastic pieces join, there are small amounts of a white epoxy. Does anyone have any advice as to how I can clean this? My initial reaction is to unscrew the print head and try soaking that but I am concerned that their is a seal that might be broken between the jets and the head. Can the whole assembly be soaked in an ultrasonic bath or will this damage the pcb and connectors? A similar image of the print head can be found here:
Any advice you can give would be much appreciated. I would really love to get this printer up and running again. Thank you in advance.
