Laser 1720DTN

Within the 1720 line, the Dell 1720DTN is the fully dressed version: the same 28-page-per-minute mono engine and 1,200 x 1,200 dpi output as its siblings, but with automatic duplexing, networking and an extra paper tray already in the box. Its appetite is modest — the high-capacity 310-8707 black cartridge is rated at 6,000 pages — while the imaging side runs on the separate 310-8710 drum unit, good for roughly 30,000 pages before it needs renewing.

The extra tray is the quiet advantage here. Load plain paper in the main tray and letterhead, forms or labels in the second, and the DTN handles a mixed desktop workload without anyone swapping stock between jobs. With a 25,000-page monthly duty cycle, it fits a busy professional desk or a small team corner that prints all day but never needs color.

Toner Cartridges for 1720DTN

Separate imaging supply: the 310-8710 drum unit, rated at roughly 30,000 pages, is replaced on its own schedule rather than with every toner change.

Which cartridge should you buy?

There is only one toner yield on this shelf — the 6,000-page high-capacity cartridge — so the real choice is quantity. A single cartridge suits a personal desk; the 5-pack listings make sense where the printer supports several people and a toner outage would stall invoices or coursework. Keep the drum out of this decision: it lasts about five toner cartridges, so budget for it separately and only when print quality, not page count, starts pointing at it.

Chip, toner and everyday use

Because toner and drum are separate units on this model, symptoms split cleanly. Fading that improves after rocking the cartridge side to side is a toner story; repeating marks or a background haze that survives a fresh cartridge usually belongs to the drum. Cartridges on this page are chipped for the 1720 family, so the printer recognizes them on insertion — if a prompt lingers, reseat the cartridge firmly and close the cover fully before assuming a fault. Page ratings assume about 5% coverage, the industry yardstick for a typical text page.

Frequently Asked Questions

Does the 1720DTN take the same toner as the 1720dn?

Yes — the whole 1720 family shares one black toner series, and the 310-8707 high-capacity cartridge listed here fits the DTN exactly as it fits the plainer models. The T in the name marks the added tray, not a different toner slot.

When do I replace the drum instead of the toner?

Plan on roughly 30,000 pages from the drum against 6,000 from each toner cartridge. If a brand-new cartridge still leaves repeating defects at fixed intervals down the page, the drum is the likely cause and swapping toner again will not cure it.

Can I make the second tray the default?

Yes — set the default paper source to Tray 2 in the driver preferences and keep Tray 1 for letterhead or special media, selectable per job. That setting lives in software; it has nothing to do with the cartridge.
