Printer works unfortunately only sporadically

I use this printer now for almost a year now and own the third version of this device. The printer started the first time after about 2 months of the original, included cyan cartridge no longer be recognized (Error Code: U150 The following ink tank :) not recognized. After "Repair" by a large electronics stores (I bought the unit at Amazon.com) did this problem after another 2-3 months. It was followed by another "repair" or another device replacement. Now also an original black cartridge is no longer recognized and I am now completely swap the device with a different printer. The Canon seems generally to have the chip ink cartridges problems, so I despite the good opinions of the trade press, has generally advise against the purchase of a Canon printer. Although the device provides good print and scan results but what good is that if the device is ever useless? You are at the research on the Internet find that this problem is anything but rare! Furthermore, the scanning VERY designed loud (really disturbingly loud) and the feel of the housing is extremely cheap. All doors and hinges creak and squeak, high quality looks quite different. It is only possible to print if all 4 cartridges are inserted that is, when a magenta cartridge is empty but only one text page (S / W) wants to print, you have to take a red cartridge anyway. Meaning? Still, it is absurd that all cartridges have to be inserted for scanning. Without inserting and realized cartridges is nothing in this device. Negative falls on the size. The printer can truly be called a force Grumpy! The dimensions are 45x17x38cm (WxHxD) and taking with me already one third of the desk. Particularly annoying the rear paper tray is the one really could make a lot less space! Other manufacturers can use the much narrower! The supplied software is overloaded and not exactly clear. Why do I have a Solution menu install the seemingly only a link to the actual program is? Only a few positive points I could find:
Installation of the printer easily albeit sluggish
-The Functionality of copying without a PC I find very convenient.
-Druck- And scan quality are quite good

Due to the problems with the cartridges I can only advise against buying a Canon printer, you will have with a Canon does not last a lifetime!
