I've purchased several replacement cartridges and all have worked great.. Disapointed in delivery time on this last one as it has not yet arrived, tracking says tomorrow.
I usually use only HP products. Although this time toner cartridges are extremely expensive nearly double which has made owning this HP laser jet not nearly as economical. I found you can purchase the cartridges can at other sites the only issue is the printer will not read them. So it will not notify HP when you run out.
I bought ALL colors with X extended capacity on each one. Install took 30 seconds.. Mailed back old cartridges for recycling purposes with easy mail back instructions. A bit expensive, but I knew they would be for laser cartridges.
