The black toner cartridges K409 for the printer specified above are supposed to last for 1, 500 pages, but I can usually print about 500 pages, and *in draft mode*...

I made an enquiry with all the details and the only reply I got was what model the printer is, although I had specified the model in the online form.

After that (and I did kindly reply with the model specs, although I had already given them all the details), I haven't heard from them, not even to know if they got my email. (As I didn't get a reply after my second email I asked them if they got my email, still no reply...)

I print a lot of music and I did ask them if music perhaps needs more ink, but I didn't get any assistance.
