Multifunction 1815
The Dell Multifunction 1815 puts a monochrome laser printer and a copier-scanner in one cabinet, and a single cartridge keeps the whole unit working: the black 310-7943. Printing, copying and faxing all draw on that one supply, which makes toner the single consumable this machine ever asks for. Below you will find it as a single cartridge and in 2, 3, 5 and 10 packs.
Multifunction machines earn their keep in small offices precisely because they replace a shelf of separate devices — and that consolidation cuts both ways. When one unit handles the office's printing and copying, an empty cartridge does not just stop the printer, it stops the copier too. Owners of the 1815 learn to treat the spare cartridge as part of the machine. The multipack listings on this page are priced for that habit, bringing the cost per cartridge down as the pack grows so the buffer stock never feels like wasted money.

Same cartridge in every row — the pack size is the only difference.
Which cartridge should you buy?
Judge by how many office jobs pass through the unit. A home-based 1815 printing and copying lightly will run a long time on a single 310-7943, and there is little reason to stock more. A small office where the machine copies contracts and prints correspondence daily should hold the 2 pack as its minimum: one cartridge working, one waiting. The 3 pack and 5 pack suit that same office once copying volume climbs, and the 10 pack is the set-and-forget choice for anyone who would rather place one order a year. In every case the arithmetic favors a buffer — the cost of a spare is small next to a day without a copier.
Chip, toner and everyday use
The chip built into each compatible cartridge lets the 1815 track toner and accept the replacement cleanly, whether the pages it prints come from the computer or the copy glass. Swap with the machine on, seat the cartridge until it locks, and let it run a test page. Yield figures for cartridges are quoted at 5% coverage, and copies of dark originals — forms with shaded boxes, for instance — spend more toner per page than typed letters do. A cartridge that fades mid-job can often be revived for a while by removing it and tilting it gently to redistribute the toner. Keep spares sealed, flat and away from sunlight.
Frequently Asked Questions
Which cartridge does the Multifunction 1815 need?
Only one: the black 310-7943. It supplies printing and copying alike, since both functions share the same laser engine.
Does copying use more toner than printing?
It can. Copies of dense or shaded originals lay down more toner than a typical text page, so heavy copying shortens the interval between cartridges.
Why buy a pack instead of a single cartridge?
Because this machine is several devices in one. A spare on the shelf protects printing and copying at once, and packs lower the price you pay per cartridge.
What warranty backs these cartridges?
Each compatible cartridge is covered by a 1-year warranty with 1-year returns.
