WiFi Interface Installation Guide
(For CLP-8301 Printer)
Safety Precautions
Safety signs ¾must be strictly observed!
WARNING Indicates a situation which, if not observed and handled properly,
could result in serious injury or death.
CAUTION Indicates a situation which, if not observed and handled properly,
could result in personal injury or property damage.
WARNING Before starting disassembly/reassembly or making adjustments, be sure to disconnect the
power cord from the power outlet.
CAUTION 1. During the maintenance work, be careful not to leave any part or screw detached or
loosened.
2. When handling a printed-circuit board, do not use gloves etc that can cause static
electricity. Since ICs such as CPU, RAM and ROM may be destroyed by static
electricity, do not touch lead wires or windows unnecessarily.
3. Do not put printed-circuit boards directly on the printer or floor.
4. When disassembling or reassembling, check wires for any damage and do not stress
or force the wires.
WiFi Interface Installation Procedure
1. Turn the power switch on the printer OFF and
remove the power cord.
2. Lift the top cover and detach the media guide in
the following manner: The media is already
unloaded. First two screws on both sides and
one screw on the center are turned with a
Phillips screwdriver and removed. Then fold the
media guide and lift it out while moving it to the
left side viewed from the front of the printer.
3. To remove the L-shaped cover of the interface
box, turn with a Phillips screwdriver eight screws
to the interface box and one screw to the top
cover lock arm and take out. Now you can look at
the main printed-circuit board.
4. Remove the serial interface board.

5. Remove the parallel interface board supplied as standard from the socket CN2 on the main
printed-circuit board. Then stand to back side of the printer and detach the parallel interface
connector by removing two screws (M3 x 5) and star washers on the parallel interface connector
plate.
6. Replace the screw holding the printer foot under the
WiFi unit. This is changed from an M4 X 12mm to M4X
10mm.
This screw is supplied with theWiFi interface kit. Make
sure that the tip of screw is not protruded over 0.5 mm
(0.002”) from the top edge of the boss on the bottom
case.
7. Identify the connectors on the WiFi module and also the connector locations on the main PCB.

8. From the inside of the printer install the WiFi
module to the interface slot where the parallel
interface was previously installed, aligning the
uppermost and lowermost holes of the WiFi fixing
plate (front panel) with the holes of the printer frame.
Then fasten it with two new screws supplied of size
M2.5. These pass through the existing threaded
holes in the printer’s case.
9. Reinstall the serial interface circuit board (from the outside of
the printer) and connect the flat cable to CN21. Note that
the clear plastic cover should be already installed on the WiFi
module to prevent accidentally touching the serial board with
the WiFi board.
11. Lastly return the L-shaped cover and the media guide to their original position and fasten them
with their respective screws.
