CHAPTER III DISASSEMBLY AND REASSEMBLY

1.SAFETY PRECAUTIONS

To avoid creating secondary problems by mishandling, be careful to follow the following precautions during maintenance work.

(1)Always turn off the power switch and unplug the power cord from the power outlet before accessing any parts inside the printer.

(2)Be careful not to lose screws, washers, or other parts removed.

(3)Be sure to apply grease to the gears and applicable positions specified in this chapter.

(4)When using soldering irons or other heat-generating tools, take care not to accidentally damage parts such as wires, PCBs, and covers.

(5)Before handling any PCBs, touch a metal portion of the equipment to discharge any static electricity charge on your body, or the electronic parts or components may be damaged.

(6)When transporting PCBs, be sure to wrap them in the correct protective packaging.

(7)Be sure to replace self-tapping screws correctly, if removed. Unless otherwise specified, tighten screws to the following torque values.
