EPS Compatible Replacement for Konica Minolta Magicolor 1600W, 1680MF, 1690MF,High Yield Pack of 4 Remanufactured Toner cartridges(A0V30HF,A0V30CF,A0V306F,A0V301F)

I ran out of black on my starter set, so I bought this whole set knowing the color ones would crap out soon too.The black replacement worked perfectly; I could see NO difference from the starter cartridge.About 6 months later (I don't do a LOT of color printing) it was time to replace the starter color toners.I replaced all 3 at the same time. The cyan and yellow were working fine so far as I could tell, but it was tough since the magenta toner was seriously faulty. The far left edge of the printout looked OK, but the 'red' faded fast. By the middle of the sheet it was very faint, and 3/4 of the way to the right edge it was 99% gone (just faint streaks). I shook the magenta cartridge vigorously, hoping to move some toner around, but it didn't help.I contacted the seller, and they PROMPTLY sent me another magenta. My color prints now all look just as good as they did with the starter set, and my printer recognized them all as new full 'Standard' cartridges. Next time I need a refill, I will buy these same ones from this same seller.I deducted the one star due to the faulty magenta PITA, but as I said, the seller took care of that VERY promptly. I'd give 4.5 stars if I could.

While I haven't had any issues with them working, they are not really comparable to the Konica toner that came with the printer. I had hopes since them were remanufactured they would produce similar quality to the oem toners. For black and white printing they work fine, but color printing the color seems to be off and is not nearly as sharp. Prints are grainy and lined, even after cleaning and adjusting the print rollers through the printer maintenance cycle.So while they were only $100.00 (for a set), it makes me sad considering the printer was only $154.00. The main problem is the actual Konica toners are anywhere between $75 - $115 EACH so they dissuade you from buying oem. I am tempted to buy a refill kit and try my luck reusing the oem toner carts, but I really don't want to ruin the printer.Bottom line is these work ok, but have made the printer mostly unsuitable for photo prints and have made it mostly black and white, defeating the reason I purchased it in the first place.I really dislike the fact that they make the toner so expensive that it is more practical to buy a new printer rather than replace the cartridges.I guess that's the 'disposable' world we live in.

I work for a private business that involves high quantities of color laser printing, and toners for the printer that we use (Konica Minolta 1600W) are pretty expensive. These help to save a lot of money, since they are far cheaper than the manufacturer brand toners. As far as we can tell, they print with decent quality and to the same page yield as the manufacturer brand toners. With this in mind, I must say that I have had an issue where I've received two Cyan toners in a package and the black was missing. That Cyan toner ended up not being recognized in our printers. So, 1 toner has defected in the 3 or 4 packs of 4 that I have bought. Overall, they seem okay with the occasional issue - not unexpected for an off-brand toner.

I was initially concerned by the low price and mixed reviews. But I couldn't be happier. I saved quite a bit of money compared to other non-KM replacements and a LOT of money compared to getting them directly from KM. The cartridges installed without any problem...no leaking toner, no messages on the printer even hinting that it could tell these weren't from KM.We use the printer quite a bit for a small family...lots of coloring pages and animal fact sheets for the kids and schematics and safety data sheets for the adults, so we use a fairly even balance of B&W and color pages. All three color cartridges still report over 90% and the black toner is at 88%. Based on these numbers, the final page count should be right at the high-capacity number from KM, so no concerns about being shorted on toner either.The print quality is excellent. No smears or smudges, even detailed circuit schematics are crisp, clear, and sharp.I think these are an excellent product at an excellent price. I've seen no issues with quality or reliability, so I can highly recommend these replacement cartridges.

So far I've only replaced the Black and Yellow toners, but the print quality is quite adequate. It's not as glossy as the OEM toner, but a fraction of the cost.I did encounter some issues replacing the actual toner, which I blame more on my own ignorance and Konica/Minolta's design, rather than this toner itself. Once I learned how to manually rotate the toner in the machine, I was in business. But before that, i accidentally dislodged the yellow toner roller, causing some toner to spill out onto my pants and carpet (oops).It'd be nice to see model-specific instructions included with the toner (e.g. instructions on how to manually rotate the toner). But either way, it's a good value.

I purchased the 4-pack as all of my starter color toners were out and I figured I'd need the black one at some point. I installed the color toners and the printer picked each up without issue. I have not tried the black one yet. As of yet, I have not noticed any issues with color printouts.The only reason I have it 4-stars instead if 5 was due to the cartridges being a little messy with spilled toner. I took each out to the garage and used canned air to blow off the bit of toner that spilled out.- Merg

Bought these to replace the starter toner cartridges in my daughter's 1650en printer. Had no problems installing these, once I figured out how to rotate the toner drum holder (insert small object like a key into the slot to the left of the toner drum and it will then rotate freely). Been used for about 2-weeks now and so far, no issues.Gave these a 4-star rating as they work great so far but I don't have much history on them yet.I would recommend this to a friend.
