The way is gahandhabt as the toner capacity of the product is very annoying. Arbitrarily declared the software, the toner needs to be changed, even if the print quality 1A remains. In this way, proper toner could be the still used by the printer simply no longer accepted. Who does not have a replacement toner at hand can not print, regardless of whether its toner theoretically still has enough ink or not.
There are in this printer strike no warning, so that it can happen to urgently need to print pages, but to stand before a printer that just will not play. Unfortunately there is no way to overcome the Druckerstreick except a new toner to buy.
All this leads to a lot of trouble, a greater pollution than necessary and a waste of money because toner must always be changed before they are actually exhausted.
I recommend another manufacturer, because Brother seemingly at all its laser printers chooses this customer-unfriendly approach.
