INK ROLLER REPLACEMENT
If printing is blurry even when the ink roller is in the proper position, replace the roller.
Ink roller: Type EA-772R
WARNING
APPLYING INK TO WORN INK ROLLER OR USE OF UNAPPROVED INK ROLLER MAY CAUSE SERIOUS
DAMAGE TO PRINTER.
1) Set the power switch to OFF.
2) Remove the printer cover. (Fig. 1)
3) Hold the top of the ink roller and remove the roller by
pulling it toward you and then upward. (Fig. 2)
4) Install the new ink roller in the correct position. Make sure that the roller is securely in place. (Fig. 3)
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
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. (Fig. 1)
2) Turn the power on and feed the paper by pressing
. (Fig. 2)
3) Lift the attached metal paper holder up and insert the paper roll to the paper holder. (Fig. 3)
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 “0䡠E” 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 exceeds 12 digits.
(Ex.
999999999999 1 )
3. When any number is divided by zero. (Ex. 5
0 )
