So far always put toner manufacturer. Attracted by the price, I tried the experiment: => Not noticed any obvious difference in print quality (to be confirmed over time and when I would change the toner 4 - auj'hui 2/4) That said, the risk of falling on faulty or damaged toner is real. Of the 4 I have received that the bracket was broken (and reattached roughly) with visible powder leaks .... Coup bowl: this does not seem to disturb the operation of the printer .. .
