What this product is

A three-pack of compatible toner cartridges in cyan, magenta and yellow from eSquareOne. Each cartridge is rated for approximately 1400 pages at 5% coverage and replaces Dell 331-0777, 331-0780 and 331-0779. The set is designed for use with Dell 1250C, 1350CNW, 1355CN, 1355CNW, C1760NW, C1765NF and C1765NFW printers.

Who this suits and who it does not

Suitable for owners of the listed Dell colour laser printers who need a full set of colour toners at high yield. Not suitable for monochrome-only printers, for printers outside the compatibility list, or for users who require original Dell-branded cartridges.

The specification that decides fit

The cartridges must match the Dell 331-0777, 331-0780 and 331-0779 part numbers and fit the compatible Dell models listed. Verify your printer model against that list before ordering.

Questions about this item

How do I install the cyan cartridge into my Dell 1355CNW and what step is often missed?

Open the front cover, pull out the old Dell 331-0777 unit, shake the new cartridge gently side-to-side five times, remove the orange sealing tape completely, then slide it in until it clicks; the step most people skip is removing the full length of sealing tape before insertion.

What part will need replacement after the cyan toner runs out at 1400 pages?

Each cartridge in this 3-pack is a single-piece toner unit; when the 1400-page yield is reached you replace the entire cartridge — there is no separate drum or developer unit to change on the Dell 1250C series.

At what temperature does print quality start to degrade during long print runs?

The cartridges are rated for continuous operation between 10°C and 32.5°C; sustained printing above 32.5°C can cause toner to fuse unevenly and produce faded or streaked output first.
