Hi there, I have a Phaser 4510DT printer that has lately been having issues with print cartridges. Model Phaser 4510DT Operating System(OS) 8.60 PostScript(PS) 4.11.2 Engine(Eng) 3.00.00.00 Networking(Net) 40.52.06.01.2009 Adobe PostScript 3016.101 (9) PCL 5e/6 Version 7.0.1 When I put in a toner cartridge, within 1 week it will now say "Replace Toner Cartridge" and not print. Sometimes reseating the toner will get it to print another page (just one!). Printer logs show a very low number of pages having actually been printed. Toner: Hi-Capacity 113R00712 Genuine XEROX How can I determine what the cause of this issue is?
