Dell 310-7945
The 310-7945 and its sibling 310-7943 form the black toner set for Dell's 1815, 1815n and 1815dn printers and multifunction units, joined by the alternate part numbers PF658, PF656, RF223 and NF485. This page collects the compatible listings sold under the 310-7945 number, all of them high-yield. As monochrome machines, the 1815 series need only this one black cartridge — simple to stock and simple to replace.
The 1815 line sits in the small-office and home-office tier: compact mono machines, the dn adding networking and duplex, with multifunction variants covering copies and faxes from the same single supply. Owners of these printers tend to value predictability over everything — one cartridge, known behavior, no color set to manage — and the family's split into standard and high-yield options lets light and steady users each land on the right size.

Which cartridge should you buy?
The listings here are the family's high-yield size, which suits any 1815 that prints most days: fewer changes and a lower cost per page than the standard-capacity version. A single cartridge is right for one machine in a home office; the 5-packs fit small offices that keep a shared shelf or run the networked 1815dn as a team printer. The Premium Quality build is the step-up version of the same cartridge. If your printing is truly occasional — a few pages a week — the family's standard size remains a reasonable alternative, since it gets used up while the toner is at its best.
Chip, toner and everyday use
Faded bands running across the middle of the page are this family's classic low-toner signal: take the cartridge out, rock it gently side to side to redistribute the remaining powder, and you will usually recover even print for a while — but treat it as notice to order, not a fix. Seat replacements fully so the chip makes contact, and keep the spare sealed and flat in a cool spot. On the multifunction models, remember that copies and faxes draw from the same cartridge, so total pages, not print jobs, decide when it empties.
Frequently Asked Questions
Which of these numbers is the toner cartridge?
The 310-7945 and 310-7943 numbers, plus PF658 and PF656, cover this printer's toner cartridges in their standard and high-capacity versions, while RF223 and NF485 are alternate part numbers for the same family. Match the number on your current cartridge, and do not order by printer model alone — similar Dell models use different supplies.
My prints have faded bands across the middle. What is wrong?
That pattern usually means the cartridge is running low and the remaining toner is no longer coating the drum evenly. Rocking the cartridge side to side redistributes the powder and restores density temporarily; a replacement cartridge is the lasting answer.
Does the 1815dn use a different cartridge from the 1815?
No. The 1815, 1815n and 1815dn — printer and multifunction variants alike — all take this same black cartridge family.
Standard or high yield for light use?
For a few pages a week, the family's standard-capacity size is the economical pick and will be consumed while fresh. Once the machine prints daily, the high-yield listings on this page win on both cost per page and convenience.
