Question about HP OfficeJet r40 InkJet Printer
I have had this copier for years and it has always out done any of our new ones, even those especially for photos. Now get ok colors sometimes, sometimes red tones, yellow seems to clog. I have been trying to print some black and white photos, scanned in and just copying. Both ways I get blue and white. I tried using the black option for copying and the color option, still blue. Any ideas? I have a pretty new black cartridge.
HP uses a system for black that prints a base ie: Cyan / *blue then overprints it with black...
Sounds like you are either out of black or you have an ink clog?
If so... you need to use a print head cleaner like Magic Inkjet Flush you can get a kit on Ebay.
