Hi Vartkes, I live in a dryish moderate climate, and have had zero issues with my 2 year old baby. Sometimes I don't print for a couple of weeks or longer, but I always fire it up and print off an A4 test print weekly on cheapo paper when it's not in use, and generally I don't do a lot of printing. Only once did the nozzle check show signs of blockage, and a single clean had it perfect again. I also take the cartridges out and give them the recommended shake on about a monthly basis.
