I expect my questions have been asked before so I tried to search for Canon Pro-1 and was returned "no results"... really? I must be doing it wrong!\n\nSo please let me off for asking anew:\n\nThe Pro-1 can't be left turned on all the time - it turns itself off after half an hour or so. Correct?\nCan anything be done about this?\n\nThe reason I ask is that each time it re-starts it consumes massive amounts of ink - a full set of new carts went in just FIVE off-on cycles. Is this right?\n\nThey are not OEM carts - has Canon built in a 'punishment' feature for non OEM consumables? (!!)\n\nI have been warned about the ink waste tank filling - is it true that it's a 'back to Canon' workshop job to remedy a full tank?\n\nIf I get 4 out of five "yes" replies..... anyone want a scrap Pro-1???
