DSM745E
Some departmental copiers spend half the day waiting for work; the Gestetner DSM745E was built for the floors where that never happens. Sitting near the top of Gestetner's departmental range, it pairs robust paper handling with a high-capacity toner system so interventions stay rare. That system is the Ricoh MP 3500 black cartridge, part number 884922, rated for roughly 30,000 pages a time.
Heavy-use machines punish small consumables, because every toner stop lands in the middle of somebody's deadline. The DSM745E answers with long runs between changes and hardware specified to keep moving — the same Ricoh-engineered platform the brand has sold for years, scaled up for departments that treat the copier as shared infrastructure rather than an occasional convenience.
Toner Cartridges for DSM745E
| Cartridge | Color | Page Yield |
|---|---|---|
| 884922 — Single cartridge | Black | 30,000 pages |
| 884922 — 2 Pack | Black | 30,000 pages |
| 884922 — 4 Pack | Black | 30,000 pages |
Which cartridge should you buy?
All three listings contain the same MP 3500 compatible cartridge rated at about 30,000 pages, so decide by how painful a toner-out day would be. A department that prints against deadlines should not be running on a single cartridge with no backup; the 2-pack is the minimum sensible stock for this machine, keeping one unit in reserve at all times. The 4-pack suits floors where the DSM745E is the primary device or where several family machines share one supply cabinet — the per-cartridge price is the lowest of the three, and a single order covers roughly 120,000 pages of output. Singles remain useful for satellite machines that see only occasional use.
Chip, toner and everyday use
On installation the machine reads the cartridge chip, confirms the new unit and resumes tracking toner life from full. The 30,000-page rating assumes 5% coverage per page; long runs of dense originals will consume toner faster, which heavy-use floors should factor into their reorder timing. Keep reserve cartridges sealed and stored flat in a cool spot away from the copier's warm exhaust side. When a cartridge nears the end and output fades on one side, rocking it gently end to end evens out the remaining toner and can carry the machine through the last jobs of the day.
Frequently Asked Questions
Which toner does the Gestetner DSM745E use?
The Ricoh MP 3500 black toner cartridge, part number 884922, rated for approximately 30,000 pages.
Does the DSM745E use the same toner as the DSM735E?
Yes. Its sibling the DSM735E runs on the identical 884922 cartridge, so departments operating both models stock a single toner type between them.
Are these original Gestetner cartridges?
No, they are compatible cartridges made to match the original's fit and page yield, backed by a 1-year warranty and 1-year returns. For a machine working this hard, the savings per cartridge add up quickly across a year of changes.
How do I know when to reorder?
Watch the machine's toner gauge and reorder when the reserve shelf is down to its last cartridge. At typical departmental volumes a single 884922 covers a long stretch, but heavy coverage shortens it, so floors that cannot afford downtime usually reorder at the 4-pack size before the current cartridge empties.
