ROLINE toner cartridge: Controlled compatibility, graphics capability, print density and exact fill quantityROLINE compatible with HEWLETT PACKARD No. 131A Color LaserJet Pro200 M251n, cyan approx. 1,800 pages ROLINE quality speaks for itself! No ROLINE toner cartridge leaves our production without a final check. One by one every item must proof that it complies all demands on quality: Guaranteed compatibility, graphical competence, printing density and exact volume. Thereby a cartridge is checked with up to seven different printer models. At the same time steady endurance tests take place so that the serial production complies with the demands on quality of the Quality Management. We only release a new type of cartridge if at least 200.000 to 300.000 pages were printed without any complaints - and only what was tested by us and judged good, will be saled.
