After I had the MX700 have felt 100 years of service and have so far had no problems with it, I got the known error messages, which pointed to the printhead. When googling then came but comments like "printhead exchange remains .. error". That's why I first hesitated to order a print head on suspicion. Have I then bought a different inexpensive multifunction device to only continue working once again can. But then I met a friend who also owns a MX700. Printhead tried -> running! So new MX700 printhead ordered, used, test pressure: everything was perfect, as out of the store. The high price was worth it for me as replacement printer had some weaknesses in the software supplied and was very noisy during the printing process.
4 stars because everything was as expected: ordered, delivered as ordered on time, works.
