Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
If the following seems a little incomplete, I ask for a little understanding - in my time zone in the US it is after midnight, and I will shortly be retiring to sleep. But I need to give you what answer there is to your question.
I suspect that, unfortunately, there may be no direct way of finding out your printer's page usage in a given period - except to print printed-page-count reports periodically (or, at the beginning and then again at the end, of the period you want to find out about), and note down whenever you change a cartridge or cartridges.
The reports that detail page-counts that I could find, for this printer, are as follows:
which shows, for each cartridge, the pages printed, and the pages remaining in the cartridge.
which shows PCL pages, PCL 6 pages, PS pages, pages that were jammed or mispicked in the product, monochrome (black and white) or color pages; and reports the page count
and doubtfully the
which prints out the service report. I doubt it contains page counts, but it might.
(If you need help with the specifics of printing out these report pages, let me know... but I frankly might be not responding for some hours or up to 9 hours, depending upon how long I sleep. I must ask some patience of you, please. I'm sorry the situation isn't any better at the moment.)
