Toner Tech- High Yield Remanufactured OEM Toner Cartridge Replacement Set (Q6470a, Q6471a, Q6472a, Q6473a) for HP 501A/ HP 3600 Set (Complete Set)

Installed this into our HP 3600 printer. Ever since the warranty expired on the device we've had no problem putting "generic" toner inside. I have to say this might be the best bang for my buck I've come across. I love how the whole set comes at one essentially at the price of a single authentic cartridge. The cartridges themselves seem to be made from the frame of authentic HP toner. Having said that, the printer recognizes the toner as HP authentic, so you won't get any alerts nor would you be voiding the warranty on your device if its still active. The only downfall to that is it looks like a used toner cartridge. But I have no issues. Toner seems to be working great on the paper. The toner level indicator seems to be going down as normal. I will buy again.

The cartridges were compatible with my printer. However, I noticed that my printer was running rough. I'm not sure if it was because of the cartridges. But, I never had that problem before. I opened the printer and checked the cartridges and the "red" cartridge was leaking. When I removed it, it spilled all over my office floor. I don't want to give toner tech a bad review. But, I have to believe that their product had something to do with it

Fast delivery. Cartridges all good & show full when installed.

Great deal compared to cost for the OEM cartridges. I had been running solely on my black toner for the past year due to the cost of replacing the 3 color toner cartridges I needed. I was skeptical about buying from a 3rd party but after a year of only black and white printing I decided to take a chance. All three were recognized as “genuine” HP supplies by the printer and the print quality looks good so far - no ghosting or streaking. Initial calibration did take a few minutes but subsequent calibrations seemed to be the normal time of about 30 seconds after power-up.

I ordered this item against my better judgement. The many 2-3 star reviews had me very concerned that this product was a dud, but the price for all 4 cartridges seemed worth the risk. I should've listened to the reviews. The color cartridges worked for about a week and now only the black cartridge works. It was worth the risk, but I strongly recommend you save your $100 and learn from my mistake.

I bought this bundled set to save money and the first two that needed replacing blue and cyan worked fine. A few months later, I'm done with my magenta cartridge and popped in today and it's not working. I believe it's a chip issue on the used cartridge. So the savings wasn't a savings at all. I would be careful about pre-buying ahead on refilled printer cartridges, as in my case you don't need to replace them all at the exact same time, then find this out later after the return period has expired.

So I have a HP 3600n since 2005 and has been a work horse. I needed refilled cartridges but didn't want to pay the enormous out of control prices that Staples or any other retail office supply store charges. I looked on Amazon and found these replacement cartridges at half the price of a "single cartrige" for the entire set! Crazy right but they were and perform great without a hitch! I highly recommend the seller for their offered products!!!

had an issue with streaking on black but it cleared up after awhile.
