The topic of nozzle clogging is one which pops up frequently here at the LuLa forum. I’ve read some harrowing experiences from very distressed photographers in connection with clogging problems, particularly regarding Epson printers. Having said that, perhaps no Epson printer has such a good reputation for clogless operation than the 3880. This has certainly been the case with my own Epson 3880, and though I can’t claim to have ever come even close to having left my printer ‘unused’ for 6 months, several months have passed on a few occasions before resuming printing, usually without the need for any nozzle cleaning or, at worst, just a single pass to free up those one or two stubborn nozzles. One thing I’ve often heard here from other photographers is that room humidity plays a vital role. Those photographers living in dry climates seem to have more - and more often - problems with clogging. Though I don’t live in a dry climate myself, I do use a humidifier during the winter months in order to help put back some of the humidity normal heating often removes.
Hope you continue enjoying your 3880 for many maintenance-free years to come!
