Review on Boost Your Printing Efficiency with Brother Genuine TN660 2-Pack High Yield Black Toner Cartridges, Offering an Approximate Page Yield of 2,600 Pages per Cartridge by Andrew Enriquez

Be careful I bought 2 packs as a spare when it came time to replace the ink in my printer I put one of the new packs in first but after the first few pages there printing was light on parts of the page, after contacting the brothers I replaced the photoconductor but it didn't work and I switched to other packs of ink cartridges. However, the problem persisted. Not wanting to spend more time and money, I ordered and replaced one of the SAME printers! The new printer had a small ink cartridge and worked great. When this ink cartridge was running out, I decided to go with the last of the two packs. a cartridge that has been used for 2 days but i encountered the same problem! So I had a brand new printer that was showing the same bad printing problem in the middle of 1/3 of the page when using these ink cartridges! I never thought 2 bullets was bad. The new one from the store works perfectly! Of course these cartridges were bad, I ordered a lot of items from Amazon, but I can not do anything with these two devices. I have to throw them away with minimal use and cannot return them as it has been more than 30 days since the date of purchase.
