My printer, which I thought was Ole Reliable, stopped printing.
Network problem? No.
Paper jam? No.
Self Tests run OK and shows that I have 15% of toner left and have printed 4935 pages since I replaced the toner.
I remember when I bought the toner, it said 6,000 pages. Well, it said up to 6,000.
Since I tried everything else, as cheap as I am, I broke down and bought another toner cartidge.
So now its printing fine again.
That old cartridge worked for me for 3 yrs 7 months. That remaining 15% should have given me another 7 months of printing at my usage.
I was robbed!
