With the seller there were no problems, good value is OK. The printer has only granted and there were messages such unauthorized products, we can not guarantee, can not print etc ... displayed. After several attempts, the printer has stopped, the error messages and prints without problems. From the outside, the ink level can be checked and there is a lot of ink in the cartridges, as there is no sponge. During installation I had no problems. It has leaked no ink.
