The good thing is equipment does cause me a bad feeling

Print, scan, copy - all three functions met the unit normally pretty neat. All of a sudden, however, occurred color distortions in the blue / green area. These were also received after I replaced the filled yet to 1/4 cyan cartridge and had made good dozen cleaning / intensive cleaning followed by Sample Print. This reminds me fatal to the previous best of my about 10 inkjet printers. There was also a Canon model (whose name me but is no longer present after a data loss). This one day persistently refused the pressure by saying that the waste ink tank (or so) would be full. A service technician my suppliers knew this saying, and told me it was a programmed Canon limiting the life of the appliance. I was able to dispose of it properly If it turns out that even with this device, a similar trick is incorporated, this was my last Canon.
