Compatible HP 435A / 436A toner: installation guide, chip reset and savings

The compatible HP 435A / 436A toner is a black powder-toner consumable for HP LaserJet Pro laser printers in the entry-level range.

What it is and which printers it fits

It is a monochrome (black) cartridge that combines the toner and the drum in a single unit, just like the original. It is compatible with the following models:

• HP LaserJet Pro M1132
• HP LaserJet Pro M1212nf MFP
• HP LaserJet Pro M1217nfw MFP
• HP LaserJet Pro P1102
• HP LaserJet Pro P1102w
• HP LaserJet Pro P1109
• HP LaserJet Pro P1109w

If your device doesn't appear on this list, don't force the installation: first check the exact code of the cartridge you currently have fitted, usually printed on the cartridge label itself or in the printer manual.

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

Installation is identical to the original: 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, shake it horizontally a few times to distribute the toner evenly, remove the plastic seal and fit it until it clicks into place. Close the cover and switch on.

These models (P1102, M1132, etc.) do not use an electronic chip like higher-end devices, so the "cartridge not recognised" error is uncommon. If a warning does appear, try these steps:

• Confirm that you have completely removed the orange seal and the protective covers.
• Reinstall the cartridge, making sure it seats fully on both sides.
• Switch off the printer, wait 30 seconds and switch it back on to force a fresh read.

If your device does show block messages due to a software update, check our guide on how HP firmware blocks cartridges before updating.

Yield and savings versus the original

This cartridge is calibrated to deliver page coverage equivalent to that of the original on everyday office documents. The savings versus the branded consumable are significant, since compatible cartridges sit consistently below the OEM price while keeping the same laser technology. To understand what each page really costs you, we recommend reading our analysis of the real cost of printing, and if you have doubts about the quality, we ran a comparison of original vs compatible printing side by side.

To verify print quality after installing it, you can use a print test page and check the sharpness of the black.
