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

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

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
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

beginning.
