Frequently Asked Questions

Prints from our ML-1640 have gone pale down one side — will a fresh cartridge fix it?

Very likely, yes. On this machine the cartridge is a single self-contained unit carrying both the toner and the imaging surface it prints through, so the classic end-of-life symptoms — fading down one side, gray text, uneven solids — are almost always the cartridge announcing it is spent. A fresh MLT-D108S replaces the whole path in one swap, which is why the pale-print problem on an ML-1640 is usually a $49.52 answer rather than a repair bill.

Is it worth buying toner for an ML-1640 of this age?

If the printer still feeds paper cleanly and prints without jams, the economics argue yes: the machine's remaining life is unlocked by a cartridge costing about 3.3 cents a rated page, far cheaper than replacing a working printer. These compact models have a reputation for outliving expectations, and this supply exists precisely because so many of them are still in daily service.

What is the cartridge code behind this ML-1640 listing?

MLT-D108S — the code in brackets in the listing title is the supply's identity, rated at 1,500 pages. It is shared with the ML-2240 and ML-2241 listings in this family, so an office running more than one of these compact machines can treat the cartridge as common stock. Check the label of the cartridge you remove; if it reads MLT-D108S, you have the match.

What does a ream of printing cost on this supply?

At the rated yield, one cartridge covers three 500-sheet reams, so the $49.52 price divides to roughly $16.51 a ream in toner terms. Dense pages pull that figure up and light pages push it down, but as a budgeting rule for an ML-1640 doing ordinary document work, sixteen to seventeen dollars of toner per ream is a fair planning number.

What cover do I get with it?

The cartridge is protected by a one-year warranty, and returns are free of charge across the same twelve months — if the unit disappoints, sending it back costs you nothing. Full terms are published on our shipping and returns page. Support answers Monday to Friday, 9 AM to 5 PM CST.

How quickly can I get one?

Orders are dispatched from the nearest of our IL, PA, GA and CA warehouses. Because an ML-1640 usually warns you with fading prints before it stops outright, most owners order at the first pale page and have the replacement fitted before the old cartridge reaches the truly unreadable stage.
