吐槽一下brother激光打印机

打印机上大喇喇的写着“2600 page replacement toner cartridge"...结果印了300多页toner的灯就开始闪，提示要换，然后600页不到就一直亮着并且不让印了。。。一气之下要去amazon写差评，然后在评论里看到了以下方法（据说manual里写）：
===================
- Open the front cover and leave open while completing the following steps.
- Turn the printer off.
- Hold the 'go' button (or "start' button) while turning the printer on. All panel lights should be on.
- Release the 'go' button (or "start' button).
- Press the 'go' button (or "start' button) 2 times.
- Pause. All panel lights should be on.
- Press the 'go' button (or "start' button) 5 times.
The toner light should be off. (error may be flashing)
The paper light should be on or flashing.
- Close cover. The ready light should be the only light on.
====================
照着做一遍，果然又能打印了，给跪了。。。。
然后还学会了按3下go按钮，能印出当前的drum和toner状态，显示总共印了558页，remaining life: drum 94%, toner 100%....太坑爹了吧，这样还居然提示要换toner,强行不让打印。。。

好鸡贼。。。
