I believe you may be referring to my comment about leaving my former Epson R300 switched on permanently - I did it because it not only prevented unnecessary head cleaning etc of its six cartridges whenever it ws switched on previously, but also stopped the print head becoming clogged up...:-)
On the other hand, my current six cartridges Canon MG7550's manual advises to use it at least once a month to prevent the heads clogging up, although I must confess I've never suffered this problem with it. But it does go through a long starting up process when switched on.....:-(
I may start to leave it permanently ready to perform.......
