The cartridge must be loaded in the old Cartrige At first I thought the toner cartridge did not work or fit. But I learned that ybtiner cartridges are designed to replace a secondary cartridge in the original one from ybtoner. Once I understood that it was s easy to see what to do and it worked perfectly.

Great price,great product Cartridges arrived as stated,They worked perfectly in my printer. Great all around Deal from start to finish,Definitely got this merchant locked into info..

Update to 5 stars I initially gave a two star review but definitely want to update to five. Without writing a long story, customer service does as they say! They guarantee and replace a “defective” product. I thought they were not responding to my issue but I believe I was too quick to criticize. Thank you YB Toner. You are now my go to!

I had an issue with ordering the… I had an issue with ordering the incorrect toner. I was able to get some help through the customer service and get the right item shipped to me. The product works great and it is as good as quality as I expected.

Not Satisfied. I bought toner for a business client of mine. They did not work in his almost new Canon machine and the instructions sent along to bypass the machine error message was not successful. I only give three stars because I did receive a refund for what I returned. I sense this company is operating from overseas, because their emails always came late in the evening 9-10 pm EST. I will not be buying again.
