Color LaserJet 8550MFP
For large departments, the Color LaserJet 8550MFP brought late-90s laser printing in a color MFP package — one machine at the center of a department's document work. Years after launch, replacement toner for it remains easy to find: it runs on the HP 60A cartridge family, meaning C4149A black, C4150A cyan, C4151A magenta and C4152A yellow. The compatible versions of all four are stocked on this page as singles and sets.
An MFP earns its keep in more ways than a plain printer — it is the machine the department walks to — and that traffic shows up in its supplies. Copying and walk-up printing add pages nobody counted in the print queue, so an 8550MFP can reach the end of a cartridge sooner than its owners expect. The printer's own supplies-status page is the honest source here: print one before reordering and buy against real levels, not guesses.

Which cartridge should you buy?
Replacement on this machine is per color: when the status page shows one cartridge low, a single C4150A, C4151A or C4152A — or the C4149A black — puts it right without touching the others. The four-color sets are for the moments when several cartridges are low together, or when a department simply wants a complete spare set on the shelf: the standard 8500-series set, the premium build of the same codes, and the set packaged under the 8550MFP's own name all carry the same four cartridges.
Chip, toner and everyday use
If the 8550MFP does not recognize a new cartridge, work through the simple causes first: reseat the unit firmly, confirm the protective seal came away completely, and check the contacts for toner dust. Still rejected? Move the cartridge to a different slot to rule out a slot problem before concluding the cartridge is at fault. Toner levels for each of the four cartridges can be checked from the control panel's supplies menu or on a printed supplies-status page — worth doing before any big job on a shared machine.
Frequently Asked Questions
What toner does the Color LaserJet 8550MFP take?
All four 60A-family cartridges must be installed: C4149A, C4150A, C4151A and C4152A. Any set marketed as a replacement for those exact codes works in this machine.
Why does my 8550MFP not recognize a new toner cartridge?
Usually the seal or the seating: reseat the cartridge firmly and make sure the protective seal was fully removed, since leftover seal material and dirty contacts are the common causes. If it still refuses, try the cartridge in a different slot to isolate the problem.
How do I check toner levels on the 8550MFP?
Open the supplies or consumables menu on the control panel to see each cartridge's remaining level, or print a supplies-status page from the device menus for a snapshot of all four at once.
Should the whole set be changed when one color empties?
No — each cartridge is consumed independently, and copying and printing draw them down at different rates. Change the empty one and leave the rest in service.
