[H] Epson R200

[Winterlight]

I own a Epson R200 that I only use for photo, and CD/DVD. So I don't use it 
that often. I am not concerned about ink replacement, but I am worried 
about clogged heads. The manual recommends that I print at least once a 
month, and ink cartridge replacement every six months or less as needed.

My question is, should I leave this printer OFF with heads parked when not 
in use? Will this help prevent head clogging?
