LaserJet 5100DTN
The LaserJet 5100DTN was the fully loaded 5100 — duplexing, networking and an extra tray stacked on the 2000-era wide-format engine, so print rooms got double-sided A3 output with minimal intervention. It feeds on HP 29A (C4129A) toner, with the high-yield C4129X (HP 29X) extending the interval between swaps. This page stocks the high-yield cartridge in every form it comes in here: MICR single, two-, three- and five-packs, and a premium five-pack.
Top-of-the-line configurations get bought for the busiest corner of the building, and the DTN's corner was the print room. Duplex tabloid for booklets, network access for the whole department, tray capacity for long runs — the specification reads like a list of interruptions removed. What could not be engineered away is toner: a machine specified to be left alone still stops when the cartridge does, which makes its supply shelf the last piece of the no-intervention promise.

Which cartridge should you buy?
Buy for the print room, not the desk. The five-packs of C4129X are the default here — a DTN that duplexes long booklet runs will walk through a two-pack before anyone notices the pattern. Between the two five-packs, the premium listing is a build preference, not a capacity difference. The three-pack serves a DTN whose wide-format work is weekly rather than daily. And the MICR single belongs to whoever prints the checks: keep it labeled and separate, because in a busy print room an unlabeled cartridge is a cartridge that will be installed in the wrong job.
Chip, toner and everyday use
On a duplexing machine, judge the cartridge by printed sides. A DTN can show a low-toner estimate at what looks like half the expected sheet count simply because every sheet carried two pages of print. When the warning appears, rock the installed C4129X once and see how far it stretches; even, returning fade after the rock means the toner is truly spent. Keep the replacement in the print room itself — a machine bought to run unattended should not wait on a walk to a supply cage.
Frequently Asked Questions
What does the DTN add over the plain 5100?
Three things: automatic duplexing, built-in networking and an extra paper tray. None of them changes the cartridge — it uses the same C4129X high-yield listings as the rest of the family.
Does the 5100DTN print both sides of a tabloid sheet automatically?
Yes. Duplexing is built in; choose two-sided printing in the driver and the machine turns the sheet itself, at its full wide-format paper range.
Which listing should the print room standardize on?
A five-pack of C4129X — standard or premium build. Long duplex runs are this model's whole purpose, and small packs turn into constant reordering.
