So, you see, your "大量" is different from mine.

That (200-300 pages) is nothing. My main printer is Brother DCP-8085DN. I like it a lot as it has network connenctivity and duplex features in addition to copy and scan features. You can use copy and scanning features if you have a network.  As "- yanon-" mentioned, a high yield toner cartridge like TN-580 just literally lasts "too long".

Good luck with yours!
