MECHANICAL SYSTEM
In this chapter, the CLC1000' s mechanical characteristics are explained while showing how its mechanisms
operate and how to disassemble/assemble its parts.
1. Be sure to disconnect the power plug before disassembly/assembly work.
2. Unless otherwise specified, assemble the parts by reversing the steps used to disassemble them.
3. Be sure to identify the screws by type (length, diameter) and location.
4. One of the mounting screws on each cover is equipped with a washer to protect against static electricity;
be sure to use the washer when installing such covers.
5. Be sure to fit a washer on the mounting screw used for grounding wires and varistors to ensure electrical
continuity.
6. As a rule, do not operate the machine with any of its parts removed.
7. When moving the hopper assembly up/down, place a newspaper or the like on the floor in front of the
machine to prevent soiling with falling toner.
8. Keep the following in mind when handling the CCD unit for image position correction:
• Do not touch the LED assembly or the dust-proofing glass.
• Do not subject the unit as a hole to a shock, as it is adjusted to high optical precision.
• Do not apply excessive force when holding the unit to avoid deforming the shutter assembly.
9. Keep the following in mind when replacing the DC power supply unit:
If you find a melting fuse in the DC power unit, replace the DC power supply unit as a whole. (Mere
replacement of the fuse could lead to damage on the machine, as such would not remove the cause of the
melting fuse.)
10. Try not to touch the image position correction mirror unit unless you are replacing it. (Avoid any
cleaning, if possible.)
11. Do not clean the No. 3 mirror (inside the laser scanner) mounted for each color.
