🖨️ High-Yield Aztech Compatible Toner Cartridge Replacement for HP 201X CF400X 201A CF400A: Black, 2-Pack - Efficient Ink for HP Color Pro MFP M277dw M252dw M277n M277c6 M252n M277n Printer Review

After less than 100 pages with the first black toner cartridge, pages started to print with black haze in the printable area. I replaced the cartridge with the 2nd and cleaned the pages, it prints normally. Hope the 2nd lasts longer but not breathless.

The product turned out to be complete garbage. It wasn't even 20 prints, there were problems with the press and the roller. I tried a cheaper alternative to original HP cartridges, but never again. Thank you for making this decision easy for us.

The first set of cartridges worked very well. So I bought another set. The new set worked fine for a few days, and then the documents started to print sparsely with black vertical spots. I have cleaned the cartridges to no avail. The only thing that worked was replacing the cartridges with HP brands. The second set of AZtech cartridges wasn't worth the money.

I have used Aztech toner for many years. The toners are of good quality and work well with my HP color laser printers. I only received two bad ones out of the many I ordered. The prices are much cheaper than HP toners and they are very happy to continue using their toner cartridges.
