I doubt an electrical or circut board issue would be fixable.īUT I have been pretty rough on the print head the past few days and just now I cleaned the electrical contacts, now I am getting the hardware failure error. Makes me think it's an electrical contact issue. For a few minutes I got all the lights to turn on and printed 1 test page, but then they stopped being recognized.

Even worse are print heads sold as new in what looks like OEM boxes and sealed in plastic bags but are refurbished in counterfeit packaging. Soaking the print head for several days may be required for best results.Ĭare must be given to letting the electronics on the print head dry thoroughly before installing the print head or else you could have an electronic short and irreparably damage the print head and/or logic assay board in the printer.Īs you know by now, buying a refurbished print head is a crap shoot.
