WorkCentre 3345
The WorkCentre 3345 keeps its supply list as short as a supply list gets: one black cartridge, the 106R03622. Under this model's own name the cartridge is sold as a single, a 2 pack and a 4 pack, and nothing else on this page needs matching — every listing gathered here is that same black cartridge in a different quantity. The code is also the one that feeds the Phaser 3330 and the WorkCentre 3335, so the 3345 belongs to a small family of machines that all drink from the same toner well.
That sharing is the practical story of this page. Offices rarely run one machine in isolation, and a 3345 sitting alongside its 3330-series relatives asks for exactly one spare on the shelf — one box that rescues whichever machine runs dry first. Nobody has to check a label twice, nobody orders the wrong code, and a cartridge bought for one model is never stranded when another model is the one that stops.

Which cartridge should you buy?
With only one code in play, the buying decision here is purely about quantity. A single cartridge suits a 3345 that prints in short bursts with quiet weeks between them. The 2 pack is the sensible default for a machine in daily service: one cartridge in the printer, one sealed in reserve, so a low-toner warning never becomes a stopped job. Shared machines and busier desks justify the 4 pack, which cuts the cost per cartridge and stretches the time between orders. Rated yields for each option are printed on the product listings themselves. Every compatible cartridge on this page is covered by a 1-year warranty and 1-year returns.
Chip, toner and everyday use
The 3345 reads a chip on the cartridge to report toner levels, so a fresh cartridge should register as full the moment it seats — push it in until it locks rather than resting it in the bay. When pages begin to fade near the end of a cartridge's life, take it out and rock it gently from side to side; the toner still inside redistributes and usually buys a run of clean pages while the replacement ships. Keep that replacement sealed, flat and out of direct light until the day it is needed, and remember that a single-cartridge machine has no backup color to lean on — the spare is the whole plan.
Frequently Asked Questions
Which cartridge does the WorkCentre 3345 take?
One cartridge covers it: the 106R03622 black toner cartridge. On this page it is listed under the 3345 name as a single cartridge and in 2 pack and 4 pack quantities.
Is the 3345 cartridge the same one the Phaser 3330 uses?
Yes — the Phaser 3330 and the WorkCentre 3335 run on the same 106R03622 code, which is why one spare can serve every machine in this small family.
Should I keep a spare cartridge for the 3345?
It is the cheapest insurance this machine offers. Because the 3345 stops when its single black cartridge is empty, a sealed spare on the shelf turns a toner emergency into a two-minute swap.
The printer does not recognize the new cartridge. What should I check?
Open the bay and reseat the cartridge firmly until it locks, wipe nothing and touch the chip contacts as little as possible, then close up and let the machine read it again. A cartridge that is merely resting in place is the most common cause of the warning.
