Why choose the genuine HP 125A toner cartridge
The CB542A is the standard yellow cartridge of the HP 125 series. All-in-one cartridge: toner, imaging drum and developer are replaced together, so print quality is like new at every change, with no separate drum to replace. Genuine HP toner powder matched to the fuser and paper of these printers: sharp text, even solids, no "cartridge not recognized" message. Colors stay consistent from one cartridge to the next.
One capacity only
The HP 125 series comes in a single capacity for this color (1,400 pages). Other colors: CB540A, CB541A, CB543A.
Printers compatible with the CB542A
Check compatibility on your printer's page.
Check the exact reference of your printer (label at the back or Information menu); suffixes (dn, dw, fdw, n) are variants of the same series and use the same consumables.
Page yield
1,400 pages per ISO/IEC 19798 (5% coverage per color, letter-type documents). Graphics or photo-heavy pages reduce the actual yield. The cost per page shown next to the price is calculated from the current price and this yield.
Installation and maintenance
Tool-free replacement: open the cover, remove the used cartridge, take the new one out of its bag, rock it gently to distribute the toner, pull the protective tab if present, then insert until it clicks. The printer recognizes the cartridge and resets the counter. Used HP cartridges are returned free of charge through HP Planet Partners.
Use and tips
The CB542A suits a lightly used printer (letters, a few documents a week): the cartridge (1,400 pages) lasts about 5 months at 300 pages per month and about 1 months at 1,000 pages per month.
Store the cartridge in its packaging, flat, away from light and humidity, and unpack it only when installing. At the "Low" alert, order: the printer keeps printing until "Very low" then "Replace". The driver's EconoMode extends life for drafts. Genuine cartridges preserve the printer's HP warranty.
