I needed to replace my black ink (for the first time) shortly after being self-quarantined & needed it quickly as I was now working from home. I was concerned it would take a very long time to arrive since everyone was buying everything online & deliveries were taking several days to several weeks to arrive. Much to my surprise, it arrived very fast & the cartridge was SO easy to replace. I love my printer and have never had a problem in the 8 months I've had it.
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.
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'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.
