Whats going on w/HP21 Ink cartridges? I purchased one 3/9 fr a local Walmart that didn't work & they wouldn't take it back. I traveled to buy another one fr a office supply store 45 min fr where I live. That one worked but stopped 4/10 - less than 50 pgs.

Can I use 2 #21 black cartridges instead of one #21 black and one #22 tricolor in my HP desk jet printer F4180?

Asked by: Anonymous
Thank you for your question! No, you can print using only the black cartridge, but when two cartridges are installed there must be a black cartridge and a color cartridge in the correct slots.
