Compatible HP 142XL W1420XL toner: installation and compatibility

Where a product page states a page yield, check its declared test protocol: ISO/IEC 19752.

What it is and which printers it fits

This is a black toner cartridge designed to replace the HP 142XL in compact office and home machines. It is compatible with exactly these models:

• HP LaserJet M211d
• HP LaserJet M211dw
• HP LaserJet MFP M236dw
• HP LaserJet MFP M236sdn
• HP LaserJet MFP M236sdw

If your printer is one of these models, the cartridge fits both mechanically and electronically. Before buying, check the reference printed on the cartridge you are removing: it should read 142XL or W1420XL. The XL version is the high-capacity one; there is also a standard variant with a lower yield, so make sure you need the 2,200-page version.

How to install it and what to do if "the cartridge is not recognised"

Close the cover and turn the machine on.

Each unit incorporates a compatible chip that reports the toner level to the printer. If, once installed, a message such as "cartridge not recognised" or "non-genuine" appears, it can usually be resolved as follows:

• Switch off the printer, remove the cartridge, gently clean the chip's gold contacts with a dry cloth and put it back.
• Turn it off completely for about 30 seconds and switch it back on to force the chip to be re-read.
• If the machine lets you carry on despite the warning, accept it: it is an informational notice and does not stop you printing.

Bear in mind that HP releases firmware updates that can block non-genuine cartridges. If your printer works fine with compatible consumables, consider disabling automatic updates to avoid any surprises.

Yield and savings compared with the original

The difference is in the price: a compatible cartridge notably reduces the cost per page without sacrificing reliability, which is especially relevant if you print regularly.

Your Startoner consumable is covered by a three-year legal conformity guarantee. Printer coverage is governed by the manufacturer’s terms and may exclude damage caused by consumables. Using a compatible cartridge does not by itself establish the cause of a fault; keep your documentation and contact us if a problem occurs.
