Frequently Asked Questions

Who honestly needs drum units four at a time?

Offices running more than one Dell Laser 1720 or Laser 1720dn, and single-printer offices with genuinely heavy volume. A drum is a wear part with a 30,000-page life, so a small fleet eats through units on a predictable schedule — and every change is unplanned downtime if the replacement is not already in the building. This 4 pack of 310-8710 drums exists for the stockroom shelf, not for a home printer that sees a few pages a week.

What does buying four do to the price per drum?

It brings each 310-8710 down to $46.35. Four drums bought singly would cost $240.84; the 4 pack is $185.39, a saving of $55.45. Spread over the 30,000-page rating of each unit, the drum cost of a printed page falls to roughly 0.15 cents — the cheapest way to buy this drum, and the saving comes from the pack size, not from a lesser part: all four units are the same drum sold singly.

How far does 120,000 pages of drum life actually go?

Each drum contributes up to 30,000 pages, so the pack holds 120,000 pages of imaging life in total. Put it in office terms: a printer doing 2,000 pages a month takes about fifteen months to wear out one drum, so four units cover roughly five years of that machine — or get shared across a fleet of 1720 and 1720dn printers, where the same stockpile turns over much faster. Either way, drum changes stop being emergencies and become routine shelf stock.

How do we know it is the drum — not the toner — that needs changing?

Drum wear has a signature: spots or marks that repeat at the same interval down the page, vertical streaks, a gray film over the whole sheet, and output that looks washed out even right after a toner change. The quick test is to fit a toner cartridge you know is good; if the same repeating marks stay in exactly the same places, the drum surface is worn and the 310-8710 is the part to replace. Toner problems fade unevenly and improve with a new cartridge — drum problems don't.

Should every 1720 owner stock four drums?

No — and we would rather say so. If your Laser 1720 prints lightly, one drum can last years, and tying up $185.39 in spares that sit for a very long time makes little sense; the single unit or the 2 pack fits that pattern better. The 4 pack pays off when drum changes are a recurring event — several printers, high monthly volume, or a hard requirement that a worn drum never stops work while a shipment is in transit.

How do warranty and returns work on a pack of four?

All four units are compatible Clever Supplies drums covered by a 1-year warranty and 1-year free returns, under the terms set out on our Shipping & Returns page. The pack ships from the closest of our IL, PA, GA and CA warehouses, and if anything in it gives you trouble, support is available Monday to Friday, 9 AM to 5 PM CST. Keeping the units sealed until their turn comes protects both the drums and your options.
