LaserJet 5100TN
Networking and an extra paper tray made the LaserJet 5100TN the shared-workhorse configuration of HP's 2000 wide-format line — departments with steady A3 volume chose it and stopped thinking about paper. Its cartridges are the familiar HP 29 pair, C4129A standard or C4129X (HP 29X) high-yield, and the shelf here is all high-yield: MICR single, two-, three- and five-packs, and a premium five-pack.
The TN formula — tray plus network — turns a printer into infrastructure. The extra tray holds the second paper size so nobody hand-feeds tabloid stock, and the network connection means the whole department queues to it. Machines configured this way print more than their base-model siblings simply because they are easier to use, which is precisely why their toner planning deserves the extra minute this page asks for.

Which cartridge should you buy?
Infrastructure printers get infrastructure buying. The five-packs of C4129X exist for machines like this: a shared TN that runs dry mid-morning generates a queue of annoyed colleagues and at least one urgent, overpriced emergency order. The three-pack is the compromise for moderate departments, and the two-pack is honestly the minimum anyone should run a networked A3 printer on. Keep the MICR single segregated for check duty so nobody burns the expensive magnetic toner on meeting agendas.
Chip, toner and everyday use
Two habits keep a TN healthy. First, rotate stock: install the oldest spare first, because toner that waits years in a cupboard settles harder than fresh stock — a slow rock end to end revives most of it, but rotation is cheaper than rescue. Second, teach the department the fade test: even fading across the whole page means the C4129X is low, while streaks and repeating marks point at the cartridge's drum surface instead. The distinction saves one perfectly good cartridge a year in most offices.
Frequently Asked Questions
What do the T and N in 5100TN stand for, practically?
Tray and network: an additional paper tray over the base 5100, and built-in Ethernet. Neither changes the toner — this model drinks the same C4129X as every other machine in its family.
How many spare cartridges should a department keep for a TN?
At least one beyond the working cartridge, and a five-pack on the shelf if the printer serves a whole floor. Shared machines fail socially before they fail mechanically — the queue notices first.
Can the 5100TN share spares with our older 5000N?
Yes. Both take the HP 29 family, so one shelf of C4129X packs covers the two machines and every other model listed below.
