Printhead are wearing parts, so the statement by an employee of another printer manufacturer.
Because the printer with 3.5 years of full use makes (studying texts, Power Point and color printouts) with good services, I risked the printhead exchange. 1) Avoid electrical 2) of successors will cost 190 Euro 3) wenns should really be subject to wear, then you have to live with it.
The matter was limitable where the error was due to testing. I had briefly then immediately passed the B200 error on the U051 error. By simple extension of the print head, I received the message "Printhead inserting" U052. So it was clear, the rest are still working and you kanns risk. If somewhere the print something smells burnt or not these changes appear on the display, the printer is probably really ripe for the scrap.
Hope it now goes on a few more years!
The price is very high, but I guess that is now for all products in all sorts of countries and so on system. Parts expensive repair unprofitable etc ... Too bad for the environment.
The printhead is but in the end the heart and thus with 1/3 of the price by the successor MP640 not so extremely bad. Of course, you already get for the amount of new printers, since I do not loyal to me 50 color pages per week to hunt over it ...
