Our toner meets the different requirements of our systems. UTAX original toner is neither toxic nor carcinogenic. This is confirmed by the AMES test. The test results are stated in the security data sheets. Some of our copiers have a sealed self contained toner system that eliminates disagreeable physical contact with the toner. These advanced copiers leave no toner residues at all.Compatible Printers: Utax 5057 Ci, Triumph-Adler 5057 Ci, Utax 6057 Ci, Triumph-Adler 6057 Ci, Utax 6006 Ci, Triumph-Adler 5006 Ci, Utax 5006 Ci, Triumph-Adler 6006 Ci, Utax 5007 Ci, Triumph-Adler 5007 Ci, Triumph-Adler 6007 Ci, Utax 6007 Ci
