Only with this original there are never problems, providing technical know-how!

The negative reviews I can not understand and they testify at most from the fact that the authors have little technical knowledge of ink cartridges.
All my following statements refer only to the original Canon Colour Ink Cartridge BCI-24 Color! These are an old cartridge for Canon printers, which are no longer in the market for a long time. Since hardly anyone uses these printers, the demand is minimal for these cartridges. Therefore it is in the Internet services sometimes to old stocks which are low in fact or even dried on the finish area. What many do not know well packaged cartridges losing dramatically in years of storage on weight and are therefore always empty! A full cartridge weighs capless 32.8 g and a completely empty cartridge weighs without protective cap about 18 to 19 g! So just weigh again on the letter scale, if you want to know how full the supplied cartridge.
In the finish area dried or dried are not a problem because cartridges can be as opposed to dried printheads easily again afloat! Simply enter some warm distilled water or nozzle cleaner in a saucer and reinstellen the cartridge for a while there upright (the finish in black or 3 outlets in colored facing down). Then dab with kitchen paper and Ear Cleaner sticks. Then let filled promptly with suitable inks new or refill (this applies Reanimierungsaktion other for colored and black ink cartridges without an integrated print head).
In cartridges are sponges and is located in these sponges the ink. Therefore, no sound is heard when you shake the cartridge. The nature of the sponges 3 in genuine Canon ink cartridges is compatible with many inks, which are described for the printer as compatible.
With cheap replicas which is very often not the case and reportedly matching refill color inks do not work there just yet!
With genuine Canon ink cartridges "BCI-24color" does not happen. Therefore comes to me as a self-Nachfüller only the original in question. Even Printer stations told me about Refill problems replicas.
For black cartridges there is the way with no problems replicas.
