Query: T.C.O - High - Print quality very average -- not a good buy

I bought this printer for its low Total Cost of Ownership as the ink tanks are relatively cheap, however after about 9 months I started to get reduced print quality "banding" which are white lines or missed sections of ink from the nozzels on the Blue part of my prints which is due to blockage of the fine nozzles of the print head. No amount of cleaning could fix this which results in the requirement of a new print head. Investigations show that the cost of a replacement head is almost the same cost as the printer !!Until Canon reduce the price of replacement print heads to a sensible level i.e < 20 DO NOT buy one of these printers as you will not be impressed by the maintenance costs incurred.
