Unfortunately, the first installing the toner cartridge was not entirely without problems with me. The cartridge simply would not properly lock into place and as a result, the lid would not close. After a long, fruitless search on the internet about this issue, then I have found that there is a spring-loaded locking slider for the toner supply openings at the bottom of the toner bay which was probably just a little stiff. Pushed a few times back and forth and the toner cartridges could be inserting easily. Otherwise, the device makes a very good impression. Print quality, speed is good, volume is acceptable. The unit turns quickly into standby when it is not needed and then needed just 12 seconds for the reactivation.
