hp 312a vs 312x — same HP Color LaserJet Pro M476 toner family, but they are not a simple A/X 4-pack swap. Check what you actually need: a full standard set, or a high-yield black only.
312A is the standard-yield color 4-pack (CF380A / CF381A / CF382A / CF383A) — black about 2,400 pages; cyan / magenta / yellow about 2,700 each. Buy this when you need all four colors at standard yield.
312X is the high-yield black single (CF380X) — about 4,400 pages. Same black fit for the M476 printers. Fewer black swaps. Better black cost per page if black runs out first. There is no 312X color 4-pack in this series.
| Feature | 312A (CF380A set) | 312X (CF380X) |
|---|---|---|
| What you get | Color 4-pack (Bk + C/M/Y) | Black single only |
| Black yield | ~2,400 | ~4,400 |
| Color yield (C/M/Y) | ~2,700 each | — |
| Best for | Full-set / light color use | Black-heavy printing on the same printers |
| Printers | Color LaserJet Pro MFP M476dn / M476dw / M476nw | |
Not 305A / 201A / 410A. Read the label on the cartridge already in the printer. 312A and 312X serve the same machines, but one is a full standard set and the other is HY black only.
We sell a compatible 312A color 4-pack and a compatible 312X high-yield black, chips installed.
When to buy which: need black + colors together at standard yield → 312A 4-pack. Black empties first and you already have colors → 312X black. Do not expect a 312X 4-pack — that SKU is not what we sell here.
FAQ
What is hp 312a vs 312x in one sentence?
Same M476 printers; 312A is the standard-yield color 4-pack, 312X is the high-yield black single (~4,400 vs ~2,400 black).
Are 312A and 312X for the same printers?
Yes on the M476 family. The difference is pack shape and black yield, not printer fit.
Is there a 312X 4-pack?
No. 312X here is CF380X black only. For a full set at standard yield, use the 312A 4-pack.
Can I mix 312A colors with a 312X black?
Yes on fit — they serve the same machines. Mixing means each slot empties on its own schedule.
Does compatible toner void the printer warranty?
Using a third-party cartridge does not by itself void HP’s limited printer warranty. Damage HP attributes to a non-HP cartridge is a different question.
