Review on 🖨️ HP 201X CF400X Toner Cartridge: Black for Color LaserJet Pro M252dw, M277 Series - High Yield by Patrick Stephani

I bought the CF400X High Yield Black cartridge (with three color packs). SALES PAGE SHOWS CAPACITY OF APPROX. 2,800 pages. BUT, after installing and verifying that it worked, I printed a shipment status report saying I could expect 2250 pages. This corresponds to a discrepancy of (approximately) 600 pages! That's a WAY too big a number for "about". Differential! Something is wrong here. The prices aren't great, but getting fewer pages is just an insult! HP, you have to explain something!
