Quality ok, aaaaber ink consumption

At the end I still have a regard to the use of compatible cartridges!
For print quality mußich not say much, which is very good and in the reviews of the MG6250 and 6150 described enough (same printing units)
I bought him as a successor of my MP780, because I have individual cartridges at Canon and if necessary even the printhead (80) can change.
But what Canaon now afford with the ink consumption borders on rip-off. After 3 weeks in use I have 12 photos 10x15, 2 CD labels and 4 Letter A4 pages printed, the printer will not shut down with me, not about power socket and not via the switch on the printer itself - it is always on standby.

Every day before I started an expression he has a 3-fold purification run performed (indicated by the 3x same sound sequences in the 2 minutes, the cleaning time. After printing Anyway, a brief cleaning. After 1 week and 6 pictures the first bars of the fuel display were disappeared.
After now 3 weeks and the aforementioned number of copies have all 4 colors are exchanged, only the two black do not have a bar. The gray cartridge which should be optimized for the SW pressure, incidentally, was the first empty (for a CD label in SW.
I had previously made a Pixma MP780 even having clean runs, but the Patonen were 1/3 larger and the number of cleanings was highest 1/3 of the MG8250.

Incidentally, I have again decided on a Canon, because it not only has the advantage of each color has (have meanwhile also others) but because the print head is interchangeable, or at least to clean removable, which is very beneficial for the use of third-party inks. Kick it out irregularities in the printed image on, I take out the print head and put it (without cartridges) for 2-3 hrs. In a cleaning liquid (Liqui-Jet) and everything is OK.

The condition of the cartridge is detected by a red LED from a sensor in the printer. LED permanently on = cartridge is full / fine. LED flashes = cartridge is empty. LED off = cartridge is faulty and is not accepted.
From Lizensgründen use some manufacturers of compatible cartridges not normal red LED special infrared LED. To prevent the use of such cartridges Canon has something new came up. The new printers of the 2011 models sitting an IR filter in front of the sensor. Thus, the printer's infrared LED no longer detects and reports a defective cartridge.

Update:
Now that the first set of cartridges "cleaned empty" was now something Eigenatiges. If I (also after days of rest) some prints now, so printing starts a few seconds after the print command has been created. The printer does not advance "Putz hour" more. It seems as if the printer once replaced after the first merit of 85 euros for a set of new cartridges for normal operation. Let's see how long that lasts.
