5.3 Parts Descriptions
(1) Power Cord Insert the plug end into an electric outlet.
(2) Power Switch Power is supplied to the printer by turning this switch on.
(3) Power Lamp This lights up when the power switch is “ON” and goes out when turning
“OFF”.
(4) SEL / ALARM Lamp This lights up when the printer is in SELECT state (ON-LINE) and goes
out when in DESELECT state (OFF-LINE). The printer can print out the
data only when this lamp is on.
This lamp may blink on the following occasions.
a) When the paper roll in coming to near-end, the SEL / ALARM lamp
keeps blinking at interval of 1.0 second.
In this case, change the roll paper.
b) When the printer is in alarm state, this lamp keeps blinking at
interval of 1/4 second. Remove the cause for alarm and press the
SEL switch. (or re-switch the power on)
(5) LF Switch Paper feeding is performed when this switch is pressed (in DESELECT
status only), this is used when inserting the paper and for spacing up etc.
(6) SEL Switch When this switch is pressed, the printer enters SELECT (ON-LINE)
status. When
p
ressed a
g
ain, the
p
rinter enters DESELECT (OFF-LINE)
status.
This switch is also used when clearing an alarm condition.
And if this switch is pressed when printing, the printer enters DESELECT
status, after all the data in the buffer is printed.
(7) I/F Connector Connects through a cable to a computer etc. Please be certain that power
to both the
p
rinter and the com
p
uter are turned off when connection is
made.
(8) Cash Drawer Connector To be used to control the P.O.S. cash drawer.
(9) Printer Cover Open when replacing the Ribbon Cassette.
(10) Manual Paper Feed Knob Use to adjust the paper position (Available only on pin tractor paper
feeding model).
(11) Rear Cover Cover for paper roll.
(12) Winder Connector Use Model CBM AW-3
(13) Stacker Basket for fan-fold paper.

6.4 Loading and Changing the Paper
6.4.1 Using Paper Roll (iDP3540F, 3541)
1) Cut the paper in right angle to its longitudinal center line as shown in Fig. 7.
2) Insert the paper into insertion inlet on the rear side of printer.
3) Turn on the power switch and feed the paper by pushing the LF switch.
4) When the printing paper comes out of the clearance (paper cutter part) on the printer cover, fix
the paper by means of paper holder, then set in on the main unit.

6.4.2 Using Fan-Fold Paper (iDP3540P)
1) Remove the printer cover
2) Set the imprint face of the paper downward and put into the paper entrance.
3) If necessary to adjust the sprocket-wheel’s position, free the wheels using the lever on both sides. Slide
them to the appropriate position, and lock them back.
4) Hook some of the paper’s perforations on the sprockets and forward the paper into the printer mechanism
by pulling and turning the paper-feed knob until the paper’s tip reaches the platen.

6.6 SelfTest Printing
Your printer has a built in self print function for purpose of checking print operation without the need for any
other external device.
Procedures for Actuating the Print Function
1) Be sure that a paper roll is properly loaded.
2) Confirm that the ribbon cassette is properly installed and turn the power switch off.
3) Turn the power switch ON while pressing the LF switch, and release the LF switch after the self test
operation has begun.
In the above operation, the self print function will stop automatically when completed.
However, the self print function will not operate without paper.
6-7. Alarm and Paper Near-End Detection
This printer has the paper near-end sensor to stop the operation when the paper comes to near-end, sending out
both BUSY and FAULT signals. This status is indicated by the SEL / ALARM lamp blinking at an interval of
1.0 second.
7. Input Buffer Back-up Function
7.1 Input Buffer Back-up
If the power is turned off, or there is a power failure during printing, the data in the input buffer will be
retained. When the power comes back on, the power failure symbol (…..PD) will be printed, and then the data
which was interrupted will be printed from the beginning of the line where the interruption occurred.
Note: The input buffer back-up function may not operate properly if the related capacitor is not sufficiently
charged. This may be the case if the printer has not been operated for a long period of time. After the printer
power switch has been turned on for 10 minutes, the buffer back-up should be effective for approximately 24
hours or more.
7.2 Clearing the Input Buffer
In case it is desired to delete the data in the input buffer, the power switch should be turned on while pressing
the SEL switch. When deletion of the buffer is completed the buzzer will sound.
Please be sure to continue pressing the SEL switch until that time.
If the printer fails to work properly at the time the power switch is turned on, please delete the input buffer as
described above before inputting new data.
