Frequently Asked Questions

What cartridge number does the LaserJet 1100SI actually take?

The 1100SI uses the same cartridge as the rest of its family: C4092A, the HP 92A black cartridge. There is no SI-specific toner — this compatible C4092A is the correct cartridge for your 1100SI, rated at 2,500 pages and priced at $33.71.

Does the 1100SI share toner with the plain LaserJet 1100?

Yes. The LaserJet 1100, 1100a, 1100ase, 1100axi, 1100se, 1100xi and the 1100SI all run on the C4092A, as do the LaserJet 3200 and 3200m. If your office keeps more than one of these models, a single spare cartridge on the shelf covers every one of them.

How long should 2,500 pages last in a shared workgroup printer?

It depends on the group's habits. A small team printing 30–40 pages a day will work through a cartridge in roughly three months; a lightly used SI in a side office can stretch one cartridge past a year. Bold graphics and full-page forms consume noticeably more toner per page than plain memos, so heavy form printing shortens those estimates.

The first page out looks fine but later pages fade. Why?

That pattern usually means the toner left in the cartridge is settling unevenly as the supply runs low. Rock the cartridge gently side to side to level the powder and the density should even out for a while. When rocking stops helping, the cartridge has reached the end of its rated life and it is time for this replacement.

Is there a separate drum to replace on the 1100SI?

No. On this printer family the photosensitive drum is part of the C4092A cartridge itself. Changing the cartridge renews the drum at the same time, which is why persistent background shading or repeat marks down the page almost always clear up the moment a fresh cartridge goes in.

How are orders and returns handled?

The cartridge is backed by a 1-year warranty and 1-year free returns. We ship from warehouses in IL, PA, GA and CA, and support runs Monday–Friday, 9 AM–5 PM CST. See the shipping & returns page for delivery times and the return process.

About This Toner Cartridge for the LaserJet 1100SI

The 1100SI was the network-minded member of the 1100 family, and the units still in service tend to sit in busy corners — shared by a bench, a lab or a small accounts team. This compatible C4092A is built for exactly that duty: consistent density across long runs of text, invoices and internal forms, at $33.71 a cartridge instead of original-brand pricing.

Installation is the familiar routine — open the printer door, slide the old cartridge out by its handle, pull the sealing tape from the new one, and slide it in until it seats. Keep one spare in the supply cabinet and the SI never waits on toner; our full HP toner cartridges selection covers the other printers on your network as well.
