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

[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

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.
