Compatible HP CF280A / CE505A toner: installation, chip reset and savings

If you're looking for a reliable replacement for your HP LaserJet printer in the P2000 series, the compatible HP CF280A / CE505A toner is a direct alternative to the original cartridge, with the same mechanics and a chip that your machine reads without any hassle. Here we explain which models it fits, how to install it, what to do if the "cartridge not recognised" message appears, and how much you can save compared with the original.

What it is and which printers it fits

The CF280A and CE505A references share the same physical format, so a single cartridge covers both cases. It is compatible precisely with these models:

• HP LaserJet P2030
• HP LaserJet P2035 and P2035n
• HP LaserJet P2050
• HP LaserJet P2055, P2055d, P2055dn and P2055x

Before buying, check the reference printed on your old cartridge or on the label inside the printer to make sure it matches.

How to install it and what to do if it "doesn't recognise the cartridge"

Installation is identical to that of an original cartridge: switch off the printer, open the front cover, remove the used cartridge by pulling it out gently, take the new one out of its packaging, remove the seal and the protective tab, shake it lightly from side to side to distribute the toner, and slot it in until you hear the click. Close the cover and switch it back on.

If, after installing it, a message such as "cartridge not recognised" or "non-genuine toner" appears, don't be alarmed: it's almost always an informational warning that you can dismiss by pressing OK or Continue on the panel. To force a fresh read of the chip, switch off the printer, wait about 30 seconds, take the cartridge out and put it back in, and switch it on again. On the P2000 series there is usually no need for any additional "reset", as the cartridge has its own built-in chip.

Bear in mind that HP occasionally releases firmware updates that can make these warnings stricter. If that's a concern, we explain it in detail in how HP firmware blocks cartridges, along with your rights under the legal warranty on compatible cartridges in Spain.

Yield and savings compared with the original

The savings compared with the branded cartridge are considerable: as a rule, a compatible toner substantially reduces the cost per page without sacrificing reliability.
