Hello from Germany,
I have a 4690MF with only 15.000 printed pages which I bought new in 2011. I realized that when there is an issue with the toner cartridge (although it is still full) and sometimes when there is a "paper size error" the 4690MF declares the toner cartridge to be empty (by somewhat "burning" the chip on the cartridge). So I just exchanged the toner-chip and could print on with the same cartridge (as long there is enought toner left in the cartridge).
The last time this happened ("toner Y empty"), I made a mistake: because the chip supplier messed up the drum and toner chips, I mounted a drum chip to the toner cartridge and put it in the 4690mf. The error message then was "toner Y not installed" (instead of "empty").
I then realized the drum chip which looks a little bit different from the toner chip. So I installed a new toner chip, tried with other Y toner cartridges, but the message "toner Y not installed" is still there, and I cannot print.
I assume that using the wrong chip I killed some electronic part in the printer.
Do you have any idea or help for me to get that fixed, or did I really kill my 4690MF...?! There is still hope that it's just a fuse or something that can be replaced.
Thanks for your help and best Regards
