Color 3700DTN

Extra trays and automatic duplexing turned the HP Color 3700DTN into a high-volume color station — departments running long print jobs rarely had to touch it. The machine uses the Q2670A black (HP 308A), shelved on this page as the Compatible HP 309A (Q2670A) Toner Cartridge Black listing, together with 311A color cartridges Q2681A, Q2682A and Q2683A. Read the color note below before ordering anything but black.

The DTN was the configuration bought to be forgotten: big trays, two-sided output, a network cable, and a place in the corner of a department that printed all day. Its toner discipline matches that role — the machine's whole point is minimal supervision, so its supplies routine is built around spares on hand and warnings acted on early.

Everything this page sells for the family sits in the table; the note under it matters for color buyers.

The color box stocked on this page is the Compatible HP 3550 (Q2671A Q2672A Q2673A) Toner Cartridge 3 Color Set — the 309A set made for the 3550 line, present here as an also-stocked listing only. A 3700DTN cannot use it: this model's colors are the 311A cartridges Q2681A, Q2682A and Q2683A, and they are not stocked on this page. The table's black row is the exact-fit purchase for this machine.

Which cartridge should you buy?

Volume discipline starts with black. Long departmental runs are overwhelmingly text, so the Q2670A is the cartridge this machine consumes in quantity — buy it ahead and keep the spare in the room, because a DTN that stops mid-run stops a department. Resist one temptation on this page: the 3 color set stocked here fits the 3550 family, not this printer. The 3700DTN's colors are the 311A Q2681A, Q2682A and Q2683A, replaced one slot at a time as each empties. If your office runs both a 3550 and a 3700, label the shelves — the boxes look like cousins and the cartridges are not interchangeable. Compatible black here carries a 1-year warranty and 1-year returns.

Chip, toner and everyday use

High-volume machines reward boring routines. Check the supply levels when you load the trays, not when a job fails; the chips report each cartridge separately, so a morning glance tells you exactly which spare to stage. Rock a fading cartridge gently once to redistribute toner, then replace it at the next natural break rather than mid-run. Keep seals intact on spares until fitting, store them flat-side down and upright in the box, and never leave a removed cartridge sitting open on top of the machine — toner dust and office air do print quality no favors.

Frequently Asked Questions

We run long jobs — how many spare blacks should a 3700DTN keep?

One fitted, one on the shelf is the working minimum for this class of machine. The Q2670A is a standard-fill cartridge, so heavy departments may cycle it quickly; the shelf spare is what keeps a long run uninterrupted.

The color set on this page is cheaper per cartridge — can the DTN use it?

No. It is the 309A set for the 3550 family. This printer's color slots take the 311A cartridges — Q2681A cyan, Q2682A yellow, Q2683A magenta — regardless of how similar the boxes look.

Does the extra tray change anything about toner?

Nothing at all. Trays change paper capacity; the cartridge set is the standard 3700 family arrangement — one Q2670A black and three separate 311A colors.

Prints fade in the middle of a long run. Is the cartridge empty?

Usually yes — fading that deepens page by page is toner exhaustion, not a machine fault. Swap the named cartridge and the run can continue; pausing to rock the old cartridge buys only a handful of pages.
