It happens sometimes that there is a "runaway". - It was in this toner cartridge, which I had ordered as a reserve half a year ago, the case: the signature was reproduced as a shadow repeatedly. - No Problem! The supplier Sandte sent within one day after my complaint free another cassette plus a return slip. And this toner supplied prints that are as good as the original cartridge. Due to the good service despite lack 5 star.
