For Dell colour laser owners needing yellow refill

Suits users of the listed Dell models who want a cost-effective alternative to the original 331-0779 cartridge. Not suitable for monochrome-only printers or for devices that require a different cartridge code. Buyers who need black, cyan or magenta toner must purchase those colours separately.

Check printer model and environment before ordering

Confirm your printer appears in the compatible list: 1250C, 1350CNW, 1355CN, 1355CNW, C1760NW, C1765NF or C1765NFW. Ensure the operating environment stays within 10 to 32.5°C and 20 to 80% RH. Store unused cartridges between -20 and 40°C at 20 to 80% RH.

Questions about this item

Which Dell printer models will accept this yellow cartridge?

It fits the Dell 1250C, 1350CNW, 1355CN, 1355CNW, C1760NW, C1765NF and C1765NFW printers listed in the compatibility data.

Can I keep using the black, cyan and magenta cartridges already in my Dell 1355CNW?

Yes. This yellow cartridge replaces only the Dell 331-0779 colour slot, so the other three cartridges remain in place and continue printing.

How can I confirm the cartridge is printing correctly after installation?

Print a test page and check that yellow areas appear solid at the rated 5 % coverage; the cartridge is rated for approximately 1400 pages under that standard.
