First of all, to make sure we can offer you a quality service, your toner cartridge goes through preliminary test. The test includes density test and a test to determine whether there are dots and lines on the copy that won`t disappear after the recharge. In such cases the client is contacted by us, or if you are already at our office, the copy is being discussed with you. If everything is alright, the toner cartridge heads towards the place it’s going to get recharged. For each cartridge model we have a specialized toner, set with the necessary amount of toner according to the capacity of the cartridge, held in a hermetically sealed container to preserve the quality of the toner. Your cartridge will be recharged with high quality professional toner.
