I received delivery of the above toner in May 2014 from tintendienst.de at a price of 54.90 with the names: WB-DEL-C1660-Y, C, M, BK HC. After the printer announcing the end of the original DELL black cartridge, I replaced it and was with the cartridge WB-DEL-C1660-BK (black) print until it was about half empty. After that first appeared in print PDF files Silhouettes or double vision in Scripture and on the side. The same appearance has also been described in on-line smart printers, scanners & Co. Forum from 13.05.2014. [...] It also describes that these silhouettes resulting from toner residues remaining on the fuser and so may lead to the uselessness of the printer. The cyan cartridge of the above delivery did not fit into the opening. The latch was blocked and had to be filed. All previously exchanged cartridges (black, cyan, and yellow) bring a lot to toner strong current, so that the toner supply tube of the printer occur strong paint residues. A perfect print image was only reestablished after an original DELL Black cartridge reinstalled and the printer-delivery tube were cleaned in the other toners. I advise against using these toners.
