How long should HP toner cartridges last?
It depends on what you’re printing and how often. “Page yield” is the number of pages – tested under ISO-19798 – that the cartridges can produce before they run out.
Of the cartridges suitable for the HP colour LaserJet 150a, the 117A standard capacity toner cartridges have a page yield of 1000 pages for the black and 700 pages for each of the three colours.
How do I refill my HP LaserJet toner cartridge?
Today, it’s not worth the trouble to refill a toner cartridge. It’s possible, but messy, and often results in lower quality print if the toner isn’t distributed in the cartridge. Also, many toner cartridges would need their chip replaced or reset and neither of those is easy for the casual user.
Before the days of reliable compatible options, it was certainly worth thinking about refilling toner cartridges, but these days the best way to save money is to buy compatible cartridges.
