brother TN315C High Yield Toner Cartridge Cyan

Pros: Good quality printing and photos

Cons: Whatever Brother is using to count pages, it doesn't work. It's throwing away cartridges that were in use just two weeks. I'll never buy another Brother product.

Pros: There are no positives.

Cons: Having HL-4040's in the office we had high hopes for this printer. Unfortunately, Brother has implemented some weird page counting algorithm. We print a monthly booklet--about 30 pages, With the High Yield cartridges on the HL-4040 we get 3000 pages. With the HL-4150 and these High Yield cartridges we are seeing the cartridge replacement nag screens at 400 pages and the printer stop printing at 500 pages!

What is most upsetting is we smashed open one of the cartridges and it still had over 3/4's of the toner in the cartridges but refuses to print.

You would do better to simply throw away the printer and buy new rather than waste money on toner.
