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.
