Computerhilfen.com: my printer doesnt print red

Somehow my printer doesnt print red colour anymore. I dont understand why, colour is not empty!! What else could be the reason?  ???

Hi!
Maybe the print head (right expression?) is plugged. You should try the print head cleaning program of your printer. If the print head is plugged furthermore, you can try isopropanol or ethanol. I used the last one. You should fill a flat cover of a container with the alcohol and lay the print head into this cover for about 30 minutes or longer. Then you must dry the nozzles of the print head with cotton wool or a tissue paper. Further you can put a drinking staw over the sucking nozzle in Canon printers, fill ist with ethanol an blow into it. So the residuary color in the print head should drop out of it. Or you can use an empty cartridge, fill it by using a syringe with ethanol and let the printer do his cleaning programm. After some passages, the colour should be mixed with the alcohol and fluid. Try it.
P.S.: It's always better to describe the type of printer, OS, PC..... So, which printer do you use.

Be aware, that this is a kinda expert tip. You can ruin the ink-cadridge or maybe also the printer, when doing it wrong and inserting a not alcohol-free cardridge back to the printer.

So perhaps start first only with the printers "cleaning function".

thanks guys. Yeah, that sounds kinda scary to me and I was afraid to ruin my printer. I tried the cleaning program several times, didnt help. Then I exchanged the magenta cartridge... and it worked  ;D

But this isn't so deviously as it sounds ;) I tried it on my own printer (canon S600) and it worked. Maybe the last tip is a bit (http://www.computerhilfen.de/fachbegriffe-b-BIT.html) daring but I read about the cleaning of some printer while performing the earlier tips.
Well, everybody decides himself. ;)

cheack the red ink to see if there is any [love]
