Canon PRO-1 using vast quantities of ink
My Canon PRO-1 has started using absolutely VAST quantities of ink! I replaced a Matte Black cartridge yesterday, printed about 10 pictures at 6x4 and it needed replacing again! Printed 6 A4 pictures and once again it is empty. Other cartridges seem to exhibit similar behaviour, although not quite as extreme. Looking inside, there is no visible sign of ink leaking.
