4-pack high-yield black toner for LaserJet P1606dn

This four-pack supplies CE278A cartridges rated at 2,100 pages each at five percent coverage. It fits LaserJet P1606dn, P1606, P1600, P1566, P1560 and M1536 series printers. Each cartridge includes a new chip for printer recognition. The set is intended for offices that print high volumes of monochrome documents.

Page-yield ceiling and single-colour output

The 2,100-page rating assumes standard five percent coverage; graphics-heavy pages will reduce actual yield. Only black toner is provided, so colour printing is not possible. The cartridges are compatible replacements, not original HP units, and rely on the installed chip for page-count tracking.

Four sealed cartridges ready for quick swaps

Each toner arrives sealed in its own packaging, protecting the powder from humidity and spills during storage. The standard LaserJet form factor slides into the printer without tools or adapters. Keeping a spare on hand avoids downtime when the active cartridge empties mid-job.

Questions about this item

Should I buy the single cartridge or the four-pack for my LaserJet P1606dn?

The four-pack gives you four high-yield black cartridges at once, so you replace them less often and keep a spare ready for the P1606dn.

What does 2,100 pages at five-percent coverage mean for everyday printing?

It means each cartridge yields roughly 2,100 pages when only five percent of each page is covered with toner; dense text or graphics will reduce that number.

Does the new chip on these CE278A cartridges work with the HP 78A slot in my M1536dnf MFP?

Yes, each cartridge includes a new chip that communicates with the HP 78A slot, so the M1536dnf MFP recognises toner levels normally.
