The Printer Does Not Recognize the Ink Cartridge or Only Prints in One Color

and here is a Replacement Printhead if needed(limited quantities)

I have cleaned the printhead, troubleshot the pinthead problems (there aren't any), but my printer still does not print blue. What should I do next? Should I buy a replacement printhead?

I cleaned the printhead. However, the printer has gone from being unable to print blue, unable to print black, unable to print anything. It cannot print test page. What do I do with a totally non-functioning printer.

b10227,

It is either the Dell Series Color cartridge, I'd first try Cleaning Dell ink cartridges

If that does not work, then it may be the printhead.

The printer should be able to print a test page(alignment) with full color. I have a similar issue and suspect the color cartridge. I am slow to replace it as school is almost over and then the printer will sit for an extended period without use, so I try printing everything I need in black.

Rick

I did as you suggestted. The printer went from not ptinting blue, to not printing black, to not printing anything- including a "test print page".  I now have no way to print. What would you suggest now?

b10227,

I would check to make sure the cartridge is seated properly.
