Seems strange but my MP620 which I picked-up second-hand from a friend only worked for a couple of weeks before dying with the error: U052, incorrect printhead installed. I have refiled the cartridges with Hobbicolors ink. The coincidence is that my previous printer, an MP610, also died with a faulty printhead error. The only conomality between the two is that I used the same Hobbicolors inks to refill both, is it possible that these inks are causing the failed print heads?
Here in Poland were very popular Brother printers, because:
- there were no chips
- great opportunities for refilling
And there were many folks who sent the printer for warranty repairs after printhead failure.
They had to pay, because the serviceman just looked at ink absorber and he have nothing more to do. The case was clear - it was not the first set of an OEM inks, but dozens of regenerations.
