But this toner really beat now everything I have ever experienced.
When unpacking the blue toner from its protective packaging was the shell of the toner on and overflowing with blue toner granules (see photo). I have the toner then cleaned externally and so used. After a couple of print then got a thin vertical blue stripes all sides. Now I wanted to take out the toner cartridge and visually check for impurities, but since there is not much to consider (see second photo). Again, the toner is übersäät over with blue granules. I have the toner now again purified and used for lack of alternative again.
Then yesterday the black toner was empty and I was hoping that my misfortune is limited to the blue toner. But by no means, ächtst after inserting the toner scharz and squeals my printer every time you print such a way that you'd think he would have reached the end of its service life. Luckily I was able to move the old Original toner by shaking slightly to cooperate and now the squealing is meanwhile over.
I have no sympathy for printer manufacturers who can gild the truest sense their replacement cartridges, but I have absolutely no sympathy for well Glump that it is not then so cheap. When I then also read that these toners are supposed to be prepared for all sorts of ISO & DIN quality standards, it is of ever completely.
Absolutely not a single star worth, this toner.
