Brother DR-2250

First of all, the quality is good and the price is high enough We ordinary consumers buy a printer toner cartridge without ink. One is to go out to add toner. Those who require quality will buy a new toner cartridge. The key point of this pit is that there is no toner bin. What does the pull-down menu on the web page mean by "toner drum separation technology"? Now it costs 4% of tuition to finally understand what is "toner drum separation", and the cost of adding a toner bin is more than 600; And I can't return the goods when I open the package. Tell me to buy a drum powder warehouse again How can I know that there is no drum powder warehouse without opening the package? Can I send it to make a B-ultrasound? They won't do it! Besides, my printer is new. The toner cartridge is also original, but there is no ink. I want a new shelf, but it is useless. Keep it for standby? When the original shelf is worn out, it is estimated that this shelf will also be scrapped, so the friends who bought it must be careful not to be trapped!!!
