2) The initiation for printing (paper): yes it is a bit long and it may surprise the first time. Nevertheless, I made an impression in black and white (I do not know if this is related) yesterday and the printer has printed in 5 seconds.
The print quality on A4 paper: very good, and the front office / back (also very convenient). It is also possible to change the settings in the drying time between the two impressions; this can be useful.
Highly practical too: the cassette or paper tray before charging. It's a small drawer where you can load a lot of leaves and goes under the printer.
The rear tray is for other functions mainly photos. I have not yet printed photos.
Just a tip: in the cassette that contains A4 paper, paper weight criteria are required; gold, that wish to print a sheet of business cards on a cardboard A4 paper, it is not possible to use the tape before or the rear tray according to the printer settings.
The means to do so: in the "Product Overview," "Changing the settings of the machine from your computer", "Definition of ordinary paper source" select "Rear Tray" as the paper source. After the work, we must put the right parameters.
Thus, I could put my cardboard sheet in the rear tray normally intended to photos and the printer selected this tray for printing.
3) Scanner: convenient, fast and correct result.
4) Printer Commands are easy to use; the LCD screen is large and features are clearly marked.
5) user guide: it is very well done with clear and detailed explanations.
For printing and scanner: There has specific parameters and functions according to the selected software.
I continue to explore the possibilities of this printer and I must be happy with this purchase I recommend.
Only small problem: the ink cartridges that look to run out quickly especially 2 colors (cyan and magenta); but it is the lot of many printers I think.
That day January 20: Just a little precision on the printer startup that is long. I managed to reduce this time to a few seconds (test performed 5 times!):
Without touching anything at any parametrage I first prepared my document to be printed visual on the computer before turning on the printer; Then I turn and when the wifi stops flashing and before the printer will do its "check up" with carriage passage, etc .., I send the document for printing; a few seconds after printing begins.
