I have a 7500DN since July 2015. It has printed about 4500 pages (thick card stock 230 gsm mostly).
My first problem is that only cyan has a light line.
I've change image units among all colors, but still only the cyan has the problem.
I've cleaned the leds, still the same.
I've bought a new cyan toner, stil the same.
I've use printer's troubleshouting menu and suggestions, nothing.
Any idea, any help, please?
The other problem is that specialy red color (not pure magenta) has often smears, even from the first months of printing, but the last semester things are much more worst.
Thanks for any help
