Frequently Asked Questions

What cartridge code should I match when reordering?

C4191A — the high-capacity black cartridge behind this listing, built for the LaserJet 8100 family and its 8150 relatives. Read the code off the cartridge you remove; the big departmental machines take a cartridge sized very differently from desktop models.

How much printing does one C4191A handle?

About 9,000 pages at standard coverage. On an 8100-series machine feeding a whole department, that rating translates into long stretches between swaps even at serious daily volumes.

Why are pages coming out light on one side only?

That pattern usually means the toner inside has settled unevenly after months of sitting in one position. Removing the cartridge and rocking it gently end to end redistributes the powder; if the fade persists, the cartridge is near empty and due for replacement.

Does a departmental printer need downtime for the swap?

Barely any. The cartridge exchanges through the top cover in a couple of minutes, and the machine returns to the queue on its own. Most offices do it between jobs without anyone noticing.

What does this listing charge?

The C4191A on this page is $36.37 — a strikingly low cost of entry for a 9,000-page departmental supply, and a big part of why these older enterprise machines remain cheap to run.

What protection follows the purchase?

You get a 1-year warranty plus 1-year free returns on this HP-class cartridge. Stock is held in Illinois, Pennsylvania, Georgia and California, and our support team keeps hours Monday through Friday, 9 AM to 5 PM CST. Policies are spelled out on the shipping and returns page.

About This HP C4191A Black Toner Cartridge

The 8100 and 8150 series were built to anchor entire office floors, and they still do in plenty of organizations. This C4191A keeps that tradition affordable: 9,000 pages of dense, even black for reports, statements and forms, in a cartridge that swaps in minutes. When a machine this size stops, a department feels it — a spare on the shelf is cheap insurance. These printers also handle thick monthly cycles without complaint, and a fresh cartridge restores the crisp edge on small print that high-volume financial and legal documents depend on.
