AZ Compatible Toner Cartridge Replacement for HP 124A use in Color Laserjet 1600 Color Laserjet 2600N Color Laserjet 2605DN Color Laserjet 2605DTN (Black, Magenta, Cyan, Yellow, 4-Pack)

I've had them about a week. They fit and they work. I tried to follow the instructions the best I could but they weren't too helpful, even with the pictures. It said to remove a strip that was nonexistent as far as I could tell, and to gently shake the cartridges at a 45 degree angle to evenly distribute the toner. I did all of this. However, the colors aren't bold at all. They are fairly faint and I have to run them through twice to get decent opaqueness. This unfortunately isn't very conducive because if you don't align the paper perfect, it will looked blurred. I'm hoping it will work itself out, but it may not.

Read the whole review. So, when I first got these, I thought I got rooked. My colors were fading on my printer, so I ordered these new cartridge. Then, I replaced my old cartridges with these, and they weren't any better than the old ones. So, I started looking around on the Internet, and it turns out that there is a problem with dust in the HP printers that causes light printing, especially in the magenta color. You have to tear your whole machine apart and clean the lenses and mirrors. So I did. Then, I printed a test page with these new cartridges and they print great. Look as good as the originals. By the way, I put my original cartridges back in, turned on the override (because all that printing with dirty mirrors makes the cartridges decrement their counter on their chips) and it turns out the blue one streaks and needed to be replaced. So, I left all the old ones in except a blue one from this pack, and now I have beautiful prints.

I was getting horrific streaking from leaking cartridges and no amount of self clean routine would help. The cost of new cartridges for a color laser is nearly equal to a new low-end color laser printer, but I decided to take a chance and I'm glad I did. The AZ Supplies cartridges appear to the HP2600N to be OEM supplies with no problems. The printer is now producing good quality color printing. Each of the cartridges is well packed and protected by an inner sealed light tight bag inside an air cusion sleeve, in a cardboard box. The 4 cartridge boxes are then enclosed in a fitted cardboard box to make a sturdy shipping case. I'm pleased to be able to continue using the HP2600N rather than sending it to the recycle pile.

I highly recommend this seller. This is a very high quality set of re-manufactured cartridges for my HP color laserjet. I've bought cheaper ones from other vendors before, but they leaked toner, and wound up making streaks after very few pages printed, and did not last very long. I've been using this set for a month now, with many printed pages, and they're still printing out perfect, solid, color pages. It was definitely worth the small amount of extra money to buy this brand. The next time I need a set, I'm going to buy from this seller again.By the way, the package included a flyer with the vendor's phone and email address, and their commitment to quality. I emailed them with a question, and got a prompt reply answering my question.

These cartridges arrived professionally packed and easy to install. Initially the print quality appeared to work, but after approximately 20 pages one color (red) started to bleed onto the pages.We contacted Amazon returns and explained that only ONE cartridge had an issue. Amazingly enough, the vendor quickly sent us a replacement (red) cartridge within a couple of days.The vendor and Amazon worked well together to resolve this issue. I am a satisfied customer.

The quality of the yellow cartridge is lacking. It leaves yellow blotches down the left side of the page. I would not buy this product again.Update 4-16-2016I finally decided to spring the $$$ to replace these low-quality cartridges with genuine HP cartridges. After doing so I discovered that the printer would no longer print vivid, accurate colors. I tried every option available—repeated cleanings, resetting to manufacturer's default settings, etc., and nothing would make the printer work properly.The bottom line is this "bargain" of a cartridge set ruined my expensive printer.I've now replaced the printer with a newer HP color LaserJet model and will absolutely, positively NEVER try 3rd party cartridge replacement products/refills again! Lesson learned the hard way.

Didn't start printing correctly until about 150 pages. Yellow stills leave line on paper because of drum. Only 1 cartridge had a pull strip. For the drums to be 100% new they all look different.

I bought these replacement cartridges for my school HP 2600N printer in January 2015.This is a classroom printer for which I have to pay for my own toner. Being a teacher, this printer is used infrequently and not at all during the summer so these are basically new cartridges. According to my printer I have more than half of my ink left. But the yellow cartridge is leaking all over the inside of the printer and getting all over the roller causing my copies to have yellow film all over them.The blue cartridge front cover is falling off.This was clearly a sub quality product which I am going to have to replace before it ruins my printer.
