If I switch off my printer for more than 1 day, when powered up, it goes into a serious head cleaning routine, does anyone know if it is better to leave powered up for this reason, speaking to epson, they say it should be switched off,, (not suprising if it chews plenty of ink),, however, I am going away for 3 weeks, and wish to avoid head clogs on my new epson r3000, having just disposed of a seriouisly messed up 2880, any advice or experience would be apreciated
