1. COMPLIANCE OF SAFE REPAIR
Be sure to read this Service Manual before providing services. In the PLUS Copyboard, full consideration is
taken to ensure the safety for a fire, electric shock, injury, harmful radiation, and substance. Therefore, observe
the notice described in this Service Manual so that the safety is kept when providing services. Moreover, be sure
to observe the notice described in the Instruction Manual.
Pay attention to the following during service inspection.
1-1. Cautions during Product Movement
·It is necessary to remove the products when making the service of products put on the wall.At that time, hold
the products by two or more persons to prevent the products from dropping or a person from falling down.
1-2. Cautions during disassembling and assembling
1. This equipment contains parts under high voltage. When doing repairs, make sure that power plug is pulled
out to insure safety.
2. Make sure that parts and screws and wiring, etc. are returned to their original positions. Tube, tape and other
insulation materials have been used for safety reasons. The internal wiring has been designed to avoid
direct contact with hot parts or parts under high voltage when using clamps or other tools.
3. The parts used in this device have special safety features such as flame-resistance and anti-voltage proper-
ties.
When replacing parts, always use parts supplied from the factory.
4. After finishing operations make sure that all parts and wires have been returned to their original position and
that there has been no deterioration of the area around the location that was worked on.
5. Be sure to use an earth band (wrist band) during repair and inspection.

Tables 1: FAILURE OCCURS
Item FAILURE OCCURS
1The power lamp does not light (blink) and operate even if the power switch is turned on.
2The power lamp does not light, but operation (sheet feed or print) is performed.
3The power lamp remains turned on and off and does not light. (The fluorescent lamp does not light.) *1
4Asheet does not move even if the print button and sheet feed button are pressed.
5Print cannot be done. (Recording paper feed defect)
6Print cannot be done. (Recording paper is delivered, but nothing is printed.)
7Ablack line (dark line) put in a printing (the image read to a recording paper and personal computer).
8Printing (the image read to a recording paper and personal computer) is thin and becomes blurred or
ruled lines are read.
9Data cannot be read to a personal computer. (A personal computer does not recognize BF-041.)
*1: Notice that the power lamp blinks for 8 (minimum) to 128 seconds (maximum) because of the change in the
operating environment setting (light quantity stabilization time) for which setup utility was used.
