5.3.6 Detaching the outer covers

How to open the upper cover
Unless the correct procedure is followed when removing the upper cover, the outer
covers may be damaged, and the plastic claws may be broken. Be sure to use the
correct tools for the job. If any of the outer covers are damaged during the work, they
must be replaced with new ones.
You will have to use a recommended tool or the like when detaching the outer covers (e.g., connector
cover, rear cover, upper cover), i.e., to free claws.
To detach the upper cover, you will need to detach other covers first. Particularly, you will not be able to
detach the upper cover unless you have detached the connector cover. (For the locations of the claws, see
the following diagram.)
• Use a tool whose diameter is less than that of the holes. (hole:3mm × 1.5mm)
Using lager diameter tools may damage the surface around the holes.
• Be careful not to cause any damage around the holes.
• When detaching the upper cover, take care not to insert the tool more 20 mm in an attempt to free the
claw on the left side. Otherwise, you could damage the flat cable inside the machine.
• When detaching the upper cover, be sure to free it from the lower cover by pulling its front toward the
front after freeing the claw with the tool. For details, see the Figure 1-23 Opening the Upper Cover .
The cover opener (round-tip screwdriver) has been set as a special tool, but any precision
screwdriver with a tip diameter of 1.5 mm or less would do instead. If using a substitute,
be careful not to scratch any surfaces.
