keep the printer on and it wont get clogged beyond regular auto clean. also make sure it does not stand near heating and that the room it self is not really dry (is anyway not healthy). One big office flower does all clima a printer need :-)
Print a test muster once a week or when you can, not because you have to, but because 100 muster prints are cheaper then one cleaning and clean office paper also takes dust and rests of the art papers with it.
cover it in plastic cover against dust
if you use cartridges for long time, take them every half year out and shake them, then put back in.
epsons are made for work, they usually dont like to sit around, but 90% of issues is by just thinking that something so precise and using so thick ink can be placed near heating and left drying out without power for weeks. It cannot work.
and yes, when you have some jets clogged, dont just manically start cleaning. Each pixel (point to be precise) is printed several times over and have so high resolution that unless 2-3 nearby jets are clogged you should not see it on photo print.
Our printers sometimes sit few weeks without use and wont get clogged. Biggest clogg we had was a spider though.
if you anyway get some messy clogg, then look again at prices of inks for small printers and forgive and pet your printer with love
