4. Install the new ink roller in the correct position. Make sure that the roller is securely in place.
   
5. Put back the printer cover.

Cleaning the printing mechanism

If the print becomes 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:

• Do not rotate the printing mechanism manually, this may damage the printer.

PAPER ROLL REPLACEMENT

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.
   

DO NOT PULL PAPER BACKWARDS AS THIS MAY CAUSE DAMAGE TO PRINTING MECHANISM.

ERRORS

There are several situations which will cause an overflow or an error condition. When this occurs, "E" will be displayed. The contents of the memory at the time of the error are retained.
If an "0E" is displayed at the time of the error, "– – – – – – –" will be printed in red and must be used to clear the calculator.
Also, in rare cases, printing may stop midway and the indication "E" appear on the display.
This is not a malfunction but is caused when the calculator is exposed to strong electromagnetic noise or static electricity from an external source. Should this occur, press the key and then repeat the calculation from the beginning.

Error conditions:

1. When the integer portion of an answer exceeds 12 digits.
2. When the integer portion of the contents of the memory or grand total memory exceeds 12 digits. (Ex. 999999999999 1 )
3. When any number is divided by zero. (Ex. 5 0 )

REPLACEMENT OF BATTERY FOR MEMORY PROTECTION

Time for battery replacement
Life of the memory protection battery is approximately 2,500 hours at 25°C(77°F) with the power plug not connected to the socket.
* When the memory protection battery is weak, the date/time setting is initialised (1/1/2005, 12:00:00 a.m.).
Verify the date/time setting in the date/clock display mode when connecting the power plug to the socket.
If the date/time setting is modified or incorrect, promptly replace the memory protection battery with new one.
(The life of the pre-installed battery may be shorter than expected because of the time the calculator spends during shipment.)
