HP 143A W1143A compatible toner: guide for your HP LaserJet 432fdn
Actualizado 18 julio 2026Share
The compatible HP 143A toner (reference W1143A) is a monochrome cartridge designed for anyone who prints in black every day and doesn't want to pay the price of the original. It yields 2,500 pages under the ISO/IEC 19752 standard and is manufactured under an ISO 9001 quality system. At Star Toner you can get it for €5.98.
What it is and which printers it works with
This is a black toner cartridge equivalent to the HP 143A, not an OEM product. It is designed and validated exclusively for these models:
- HP LaserJet 432fdn
- HP LaserJet MFP 432fdn
If your machine is one of these two, this is the correct consumable. If you want to understand the real differences between a compatible cartridge and an original one, we compare them without the hype in original vs compatible, printed side by side.
How to install it and what to do if it "doesn't recognise the cartridge"
Installation is straightforward: switch off the printer, open the front cover, remove the used cartridge, take the new one out of its packaging, spread the toner evenly with a gentle side-to-side rocking motion and remove the protective seal. Insert the cartridge until it clicks into place and close the cover.
If a cartridge not recognised or non-genuine warning appears when you switch it on, it doesn't mean the toner is faulty. Try these steps:
- Switch off the printer, wait about 30 seconds and switch it back on so the machine re-reads the chip.
- Remove and reinsert the cartridge, making sure the chip contacts are properly aligned and clean.
- If the message persists, accept it or press to continue: in many cases it is simply a warning, not a block.
Bear in mind that HP releases firmware updates that can make these warnings stricter. We explain how to handle it in when HP firmware blocks cartridges.
Yield and savings compared with the original
With its 2,500 pages at the standard 5% coverage, the yield per cartridge is the same reference standard used by the original, measured with the same ISO standard. The difference lies in the cost per page: a compatible cartridge significantly reduces the cost of every print without changing your workflow.
