I purchased a Canon G3200 printer on Sept 1, 2017. It failed with a printer feed problem 5 months later and was replaced by Canon. The replacement printer has now failed 8 months after receipt,with error codes 5B00 and 5B01 (apparently an ink absorber is full). For the past 3 months it has stopped printing black with increasing frequency, and all that I could do to get the black ink flowing again was to do a cleaning. First, a normal clean worked, then only a deep clean, and finally only about 3 deep cleanings would clear it up. I am told by Canon Service that I should not be doing a deep cleaning myself (although I'm not sure who would do that if not me). I was told that air got into the feed mechanism because the caps on the ink reservoirs were loose. They are firmly installed.
I was told that even though this printed had failed after 8 months, because it is a replacement printer, there is nothing they can/will do.
So, two of these fairly expensive printers have failed in just over a year of combined use and Canon says I am simply 'out of luck' - go buy another one.
I have used Canon Cameras for many years and have been pleased with them all. My previous Canon printer, a Pixima MG5220, which was less expensive and had an actual, real, duplex printing mode, also served well for many years.
I am disturbed with the apparent quality decline in the G3200 series, and Canon's response. I will not be purchasing another Canon printer.
