From: davy on 8 Mar 2010 07:10 I would try removing the ink cartridges and then removing the print head and 'try' cleaning the copper coloured looking contacts on the rear of the print head, failing this it looks like a new print head is required, these printers are well worth it I'd say. The only thing to bear in mind is when the ink waste pad gets full, the printer then will want a reset and a new waste pad, one other dodge here is people have extended the tube feeding the waste pad and feeding a waste bottle below the desk to catch all the cleaning flushes etc. These print heads as opposed to piezo heads as used in Epson's for example, basically you have a electric kettle for each pixel in the print head that boils the ink... hence the term 'bubble jet', the ink boils bursting the bubble and 'splatters' the paper in the correct place. Sadly, these are not long life devices, just like a light bulb or kettle element they will wear out with time. One cleaning trick is to dab the head on a sponge moistened with warm water and leave overnight, re insert the next day after drying by dabbing on kitchen towel, refitting doing a deep clean and then trying again.... there are many ways cleaning a print head and people will have their own different method. davy

My black only printing had a white band also much like you are describing. I tried cleaning multiple times with different approaches, all to no avail. I played with various modes with the draft and normal modes obtaining the same problem. I worked on putting my printer into a mode where it printed with the good half only and I got it to work but very slow. The mode (I can't remember) was something like Hi Res paper and photo. I believe it was put into a unidirectional scan (probably 4 swipes) which used the good portion of my head. My analysis is that 1/2 the head is used for one direction and the other half for the reverse direction. Don't know the algorithms of the Canon S/W I finally took a chance on it being the print head and purchased a new one for about $55 and now it works as new. I don't know how the original head failed, but it did. Hope this helps, Geneo
From: rencaa on 8 Mar 2010 17:40 Mickey, exactly. It looks like when the carriage goes on the right, it prints the yellow band, but, when it comes back it doesn't. That's so strange. I tried with hot water for some minutes, tried with special cleaning liquid, did deep cleaning but nothing. I'll try with davy's tip too tomorrow... I left Epson because the ink dried in the pipe, but Canon doesn't seem better...

If cleaning fluid didn't work I doubt anything else will.... I could be wrong > it prints the yellow band, but, when it comes back it doesn't It would use the same nozzles no matter which direction the head travels, only the sequence from the nozzles would be different.... are the matrixing driver chips in the head -anyone-? Not sure on the Canon, and I have a IP5000! I'd be probably trying the head in another printer.... or trying a known good one if at all possible. davy |
