Diagnosing the KEYPAD Malfunction
Note
The PRINTER and INTERFACE must be ON and in the READY mode before you diagnose the KEYPAD.
You cannot diagnose the KEYPAD correctly if the PRINTER and INTERFACE are in the START-UP or SELF-
TEST modes.
[1] Check that the KEYPAD CABLE is connected correctly.
[2] Press the Format ▲key several times. As you press the key, observe the illumination of the NUMERIC
KEYPAD and listen for a beep each time the key is pressed.
[3] Study the following and check for incorrect or erratic displays:
• MESSAGE DISPLAY
• NUMERIC KEYPAD
• ‘COPIES’ DISPLAY
• ‘FORMAT’ DISPLAY

[4] Locate the DC-DC CONVERTER.
Important
There are 2 styles of DC-DC CONVERTER. You can
replace the DC-DC CONVERTER only if it is the same
style as the DC-DC CONVERTER replacement, Part
Number 981821, in the KEYPAD Repair Kit.
[5] Compare the DC-DC CONVERTER on the
CIRCUIT BOARD to the replacement DC-DC
CONVERTER in the Repair Kit.
[6] If the DC-DC CONVERTER on the CIRCUIT
BOARD is the same style as the replacement part,
advance to Step 7.
If the DC-DC CONVERTER is not the same style
as the replacement part, you must replace the
KEYPAD OVERLAY/CIRCUIT BOARD
ASSEMBLY. Advance to the procedure
Replacing the KEYPAD OVERLAY/
CIRCUIT BOARD ASSEMBLY on page 13.
[7] Use the following table to help you measure the
input and output voltages of the DC-DC
CONVERTER. The KEYPAD must be energized
to check the voltage.
Caution
Be careful not to cause a short circuit between any of
the pins on the DC-DC CONVERTER.
[8] If the input and output voltages are correct,
advance to the procedure Replacing the
KEYPAD OVERLAY/BOARD ASSEMBLY
on page 13.
[9] If either voltage is not correct, continue with the
next step.

[10] De-energize the LASER PRINTER or IMAGE
MANAGER.
[11] Loosen and remove the plastic BUSHINGS from
the back of the CIRCUIT BOARD. Keep the
BUSHINGS.
[12] Separate the KEYPAD OVERLAY from the
CIRCUIT BOARD. Be careful not to damage the
RIBBON CABLE between them.
[13] Remove the solder from the pins connecting the
DC-DC CONVERTER to the CIRCUIT BOARD.
Important
Two of the pins on the DC-DC CONVERTER are
wider at one end and the third pin is uniformly narrow.
Insert the narrow pin into the hole at the edge of the
BOARD.
[14] Insert the pins of the new DC-DC CONVERTER
through the correct holes in the CIRCUIT
BOARD.
[15] Solder the pins of the DC-DC CONVERTER to
the CIRCUIT BOARD.
[16] Remove the paper from the adhesive pad on the
back of the DC-DC CONVERTER.
[17] Bend the pins and press the DC-DC
CONVERTERso that the adhesive padadheres to
the CIRCUIT BOARD.
Caution
Be careful not to cause a short circuit between the pins.
[18] Energize the LASER PRINTER or IMAGE

[19] Measure the input and output voltages of the new
DC-DC CONVERTER and compare these
voltages to the table. If the voltages are not
correct, advance to the procedure Replacing the
KEYPAD OVERLAY/BOARD ASSEMBLY
on page 13.
[20] Iftheinputandoutputvoltagesofthenew DC-DC
CONVERTER are correct and none of the
STANDOFFS are broken, assemble the
KEYPAD OVERLAY and the CIRCUIT
BOARD using the 4 BUSHINGS. Advance to
Step 26.
[21] If 1 or 2 STANDOFFS are broken, remove any
pieces of the old STANDOFFS from the back of
the KEYPAD OVERLAY. The area where you
attach the new STANDOFFS must be flat.
Sandpaper or a file can be used to make the area
flat.
A broken STANDOFF could be repaired with
adhesive if the pieces can be aligned.
[22] Install each new STANDOFF and BUSHING.
Warning
Do not allow adhesive to contact skin.
[23] Place one drop of Loktite 414 ADHESIVE to the
end of each new STANDOFF.
[24] Assemble the KEYPAD OVERLAY and
CIRCUIT BOARD. Attach and tighten
BUSHINGS to the existing STANDOFFS.
[25] Apply pressure to the KEYPAD OVERLAY/
CIRCUIT BOARD ASSEMBLY for 60 seconds
until the ADHESIVE is dry enough to handle.
Important
Handle the ASSEMBLY carefully. The ADHESIVE
does not reach full strength for 24 hours.
[26] Place the KEYPAD OVERLAY/BOARD
ASSEMBLYinto the KEYPAD. Be careful not to
damage the RIBBON CABLES and other wires.
[27] Inset the four screws and washers into the back of
the KEYPAD and tighten them. If any SCREWS
are broken, replace them.

[28] Use the procedure Diagnosing the KEYPAD
Malfunction on page 3 to check for the correct
operation of the KEYPAD.
[29] Use any available diagnostics or equipment to
check the correct operation of all the KEYPAD
components and functions. For example, on some
equipment you can use the “KEYPAD LED/Tone
Test”and“KEYPADRecognition Test”underthe
Diagnostic Functions of the Interface CES Main
Menu.
[30] If the KEYPAD does not operate correctly,
replace it.
