its life might be shortened. When replacing, use a conductive mat, soldering iron with ground wire, etc. to
protect the laser diode from damage by static electricity.
And also, the SI and IC are same as above.

any screws are used inside the unit. To prevent the screws from missing or dropping, etc. always use a magnetized
screwdriver in servicing. Several kinds of screws are used and some of them need special cautions. That is, take care of
the tapping screws securing molded parts and fine pitch screws used to secure metal parts. If they are used improperly,
the screw holes will be easily damaged and the parts can not be fixed.
