In order to ensure that my printer is working properly and that I can be able to print a good number of pages with it, I have continued to use the Lexmark C5240KH OEM High Yield Black Return Program Toner Cartridge. This is because it has been able to function properly with a good number of printers and I have thereof continued using it without coming across any challenges. The ink cartridges hold as remarkable amount of ink and toner which ensures that I am able to print a variety of documents. This comes as a necessity since I can print way more documents that would be possible with a different cartridge.
