Black bar down the BACK of sheet
can someone explain why a Canon IP5200 smears a fat (about 6 mm) black fading bar
down the BACK (!!) of the sheet? This shows up every time the printer has been pausing for > 1/2 hour or so, after 4 or 5 printed pages this mysterious ink reservoir appears to be exhausted, the following sheets are clean - until after the next pause.

Sorry for chopping my question into parts - the site wouldn't accept it "all in one".
