Hi Martin,
If the printer does not use the ink monitor chips on it, you can simply
fill the old cartridge with a mixture of isopropyl alcohol and a window
cleaner which contains ammonia. I know ammonia is a bit hard to come by
in the UK.
However, most chemists (Drug stores) should have access to it, Yo want
to create a final dilution of between 1 and 2% ammonia, so if you must
be a stronger version, you need to dilute appropriately. So if you can
make a water ammonia mix that is about 3-4% and then add 50% isopropyl
alcohol to that, it will drop it to around the acceptable concentration.
If you have the types of cartridge which require the ink monitoring
chips, there are now resetters for these sold on ebay and elsewhere,
which are battery operated and good for indefinite resetting of
cartridges. I don't know how specific they need to be in terms of model
numbers. The ones for Epson printers only work with a couple of models
per type of resetter.
Once you reset the chip on the cartridges, you can refill them with
cleaning fluid. I don't know offhand where in the UK one can buy
commercial cleaning cartridges for Canon printers, unfortunately.
