Question about HP OfficeJet Pro k550 Printer
My printer is printing all the colors fine except black. Everything printed in black has streaks of white unprinted areas through it. I printed a full page of absolute solid black. It prints a full page of black with many, many white lines through it. It seems to get a little bit better over time, by printing alot of black, but that could cost more in paper / ink than a new printer. I have tried: * Replacing the print cartrige. * Replacing the print head. * Carefully cleaning the areas that interface between the print cartrige / print head and the printer. * Running all of the software service functions numerious times. * Tried all troubleshooting tips / recommendations by HP support. Anyone have any ideas? This seems crazy, what could it be? A hardware problem with the printer itself?
No cleaning was successful, finally replaced the printhead and solved the problem.

First with a clean soft cloth and a very small amt of alcohol clean off the underside of the printer carridge (the holder for the print heads) also where the print heads cleaning station is clean out any large masses of congealed link. Then remove the ink cartridge in question and with a pencil eraser gently rub the contacts and both the cartridge and the carridge replace the cartridge. Using the software tools for the printer clean and align the printheads ( if there is an option to do so). If this dosn't fix the problem try a different ink cartridge.
