Color LaserJet 3750DN
Duplexing plus networking made the Color LaserJet 3750DN the configuration busy offices gravitated toward: shared, two-sided color printing that covered the bases for a whole workgroup. Its cartridge set is the Q2670A black with Q2671A cyan, Q2672A yellow and Q2673A magenta.
Two-sided printing quietly stretches every cartridge. A department that defaults to duplex turns long reports into half the sheets, and the toner budget follows the same direction. Combined with network sharing — many users, one cartridge set — the DN rewards a simple routine: glance at the supplies levels when you pass the machine, and keep the next black where the person who changes it can actually find it.

Which cartridge should you buy?
Buy the cartridge the printer names. On a shared DN, supplies status is visible to everyone, so there is no guessing: the low color gets a single replacement, and the others keep working. Black is the exception to buy ahead on — it serves every user on the network, so a spare black beside the printer prevents the whole group stalling on one empty cartridge. Take a complete set when the machine is being set up in a new department or when several cartridges genuinely run down together. Whichever you choose, confirm the code against the cartridge coming out; the colors stocked for this printer are the Q2671A-series codes in the table.
Chip, toner and everyday use
A networked printer tells on itself: check the supplies page from your browser before ordering, because the chip in each cartridge reports the level the estimate is based on. When you install a replacement, seat it fully and let the printer finish recognizing it before the next job arrives. Two-sided work is kind to paper but concentrates toner use on busy days, and yield figures assume only about 5% of the page is covered — a run of full-color presentations will outpace the estimate every time. A gentle side-to-side rock of a fading cartridge buys extra pages while the replacement ships.
Frequently Asked Questions
What toner fits the Color LaserJet 3750DN?
The Q2670A black cartridge and the Q2671A, Q2672A and Q2673A colors. Match the code on the cartridge you remove and you cannot go wrong.
When one cartridge runs out, should I change all of them?
Rarely. Check the supplies gauge, replace the cartridge that is actually out, and let the 3750DN use up the rest — changing everything at once discards toner you already paid for.
Does duplex printing really save toner?
It saves paper directly and toner indirectly: the same document spread over fewer, fully used pages wastes less of both than single-sided printing with half-empty backs.
Can I keep an unopened cartridge as a backup?
Yes. Leave the seal intact, store the cartridge flat in normal room conditions, and it will keep well until the day the DN calls for it.
