Tear down: Inkjet printer (HP DJ F4280) (part I)

Before CNY, I cleaned out some stuff from my room. One is worth to tear down to study, printer. Honest to say, I hate HP printer because its ink is too expansive. This printer hasn't printed over 1,000 sheets probably. So my brother and I decided to throw it away to clean space.
But before throw it away, I think we could tear down it and see what look like inside.

The name of this printer is HP DJ F4280, I guess it is the cost down version of consumer level, because it has only 3 motors, one for CIS (Contact Image Sensor), one for ink x-axis motion, and final one for gear train and rollers. 

首先上蓋的部分，沒有hinge，
上蓋直接扣到Scanner的flat bed的勾槽之中！

光是拆上蓋與外殼充滿了卡勾 (Hook)
