5. Put back the printer cover.
Cleaning the printing mechanism
If the print become dull after long time usage, clean the printing
wheel according to the following procedures:
1. Remove the printer cover and the ink roller.
2. Install the paper roll and feed it until it comes out of the front of the
printing mechanism.
3. Put a small brush (like a tooth brush) lightly to the printing
wheel and clean it by pressing .
4. Put back the ink roller and the printer cover.
Note: •Never attempt to turn the printing belt or restrict its movement
while printing. This may cause incorrect printing.
•Do not rotate the printing mechanism manually, this may dam-
age the printer.
4. Paper roll replacement
Never insert paper roll if torn. Doing so will cause paper to jam.
Always cut leading edge with scissors first.
1. Insert the leading edge of the paper roll into the opening.
2. Turn the power on and feed the paper by pressing .
3. Lift the attached metal paper holder up and insert the paper roll to
the paper holder.
5. Replacement of battery for memory
protection (for EL-1607P (ACO))
Time for battery replacement
Replace with a new battery once 2 year.
Method of battery replacement
Use one lithium battery (CR2032).
Note: When replacing the battery, the set tax/discount rate and conver-
sion rate, the memory contents will be lost.
You may want to write down the tax/discount rate and conver-
sion rate, other important numbers on a sheet of paper.
1. Turn the power switch “OFF”and unplug the power supply plug
from the outlet.
2. Remove the battery cover on the back of the unit. (Fig. 1)
3. Remove the exhausted battery and install one new lithium battery.
Wipe the battery well with a dry cloth and place the plus “+”side
upward. (Fig. 2)
4. Replace the battery cover by reversing the removal procedure.
5. Press the RESET switch on the back of the unit.
After battery replacement
•Connect the power supply plug to an outlet and turn the power switch
“ON”.
Check that “0.”is displayed. If “0.”is not displayed, remove the bat-
tery, reinstall it, and check the display again.
•Reset the tax/discount rate and conversion rate.
•On the battery replacement date label found on the back of the unit,
write down the month and year when the battery is replaced, as a ref-
erence for the next battery replacement.
Precautions on battery use
•Do not leave an exhausted battery in the equipment.
•Do not expose the battery to water or flame, and do not take it apart.
•Store batteries out of the reach of small children.
Notes for handling Lithium batteries:
DO NOT PULL PAPER BACKWARDS AS THIS MAY CAUSE DAMAGE
TO PRINTING MECHANISM.
CAUTION
Danger of explosion if battery is incorrectly replaced.
Replace only with the same or equivalent type recommended by the
manufacturer.
Dispose of used batteries according to the manufacture’s instructions.

6. Resetting the unit
(for EL-1607P (ACO))
Strong impacts, exposure to electrical fields, or other unusual condi-
tions may render the unit inoperative, and pressing the keys will have
no effect. If this occurs, you will have to press the RESET switch on the
bottom of the unit. The RESET switch should be pressed only when:
• an abnormal event occurs and all keys are disabled.
• you install or replace the battery.
Note:
• Pressing the RESET switch will clear the stored tax/discount rate
and conversion rate, other data stored in the memory.
• Use only a ballpoint pen to press the RESET switch. Do not use
anything breakable or anything with a sharp tip, such as a needle.
• After pressing the RESET switch, connect the power supply plug to
an outlet. Turn the power switch “ON” and check that “0.” is dis-
played.
7. Servicing
(1) Apply grease to the upper case key hole.
At first, spray the silicon spray to keyboard of upper case from back side
(All keys).
• Grease application to one position: – = (1 key)
• Grease application to two positions: 0, u(2 keys in total)
• Grease application to three positions: (1 key)
(2) Apply grease to key and 0 key finger.
(3) Insertion of SL-SW roller into the shaft
*When inserting the ass’y into the SL-SW slider, allow a clearance
between the rib and the SL-SW roller. (Refer to the figure above.)
(4) UL tape attachment
Attach the UL tape as shown in the figure below in order to protect the
flat cable from the screw head on the key PWB.

(5) Wiring of the secondary side of the transformer
Pass the lead wire of the secondary side of the transformer through the
slit section of the rib on the upper cabinet, and attach UL tape to the slit
section to fix the lead wire.
(6) Protection tube
(6)-1. EL-1607P (AAC, ACO, ABC)
Insulate between the transformer and the AC cord connector with pro-
tection tubes (2 pcs u2 positions).
(6)-2. EL-1607P (TRC)
The EL-1607P (TRC) uses 14 protection tubes in total (that is, 2 pcs u7
positions) as shown bellow.
( 7) Ferrite core •••(for EL-1607P (AAC, ACO, ABC))
(7)-1.
Wind the AC cord around the ferrite core so that the size is as shown in
the figure below.
Wind every AC cord three times around the ferrite core.
