The price pressure forces you to place the original cartridges to so-called "compatible" to access cartridges, which are significantly cheaper. Unfortunately, you can save anything when in the "compatible" cartridges is low on toner, that instead of the promised "5000 sheets" only "a few hundred sheets (normal mix of text and images)" can be printed, as it happened to us. Unfortunately, it was not an isolated incident. We had ordered a precautionary two complete sets, both of which have shown the same behavior.
