2-3. Handling Notes

(1) Install the printer near an easily accessible socket-outlet. (2) Place the unit on a flat and stable surface for operation. (3) Do not connect the AC Power Plug to the same outlet used for other noise

generating devices (large motors, etc.).

(4) Be careful not to drop paper clips, pins and other foreign objects into the

unit.

(5) Wipe off dirt with a soft cloth soaked in alcohol or benzine. Do not use

Lacquer thinner, Trichlorethelene or Ketone solvents because they may

damage plastic parts. (6) Use a soft brush, etc. for cleaning the printer mechanism and PCB. (7) Keep hands out of printer while power is on. (8) Do not attempt to print when there is no ink ribbon or paper in the unit. The

print head life could be severly reduced. (9) If the paper is fastened tightly to the roll, the paper may not detach from the

roll when the end is reached.

If this happens, the no paper detection function and paper feed will not

operate. (10) Always keep the printer cover attached when printing to prevent paper

jams, noise, and other problems. (11) Always turn the power off before opening the printer cover. (e.g. When

renewing a ink ribbon)

3-3. Part Functional Description

(1) AC Power Plug Connect to an outlet of the specified voltage. (2) DC Power Outlet Supplies DC 12V power to the printer. (3) Printer Cover Protects the printer against dust and reduces noise. (4) POWER Lamp Lights up (green LED) when power is on. (5) ON LINE Lamp Lights up (green LED) when the unit is in the online

mode.

(6) ALARM Lamp Lights up (red LED) when printer operation is not

normal, or the printer is out of paper. It is necessary to install paper into the printer and press the ON LINE Button to recover from paper empty status. Turn off the printer power in order to recover from abnormal operation.

(7) ON LINE Button Toggles between the on-line and off-line modes. The

printer will go on-line after turning power on.

(8) FEED Button Momentary operation of this button provides one

line feed. Pressing this button continuously will cause continuous paper feed. If power is turned on while pressing this button, self printing*1 will be performed.

(9) Interface Connector Connects the printer to host computers. Check that

both computer and printer are off before connecting.

(10) DIP Switches Allows for setting of various functions according to

user requirements.

*1 Self Printing This printer has another convenient function, the

Automatic Test Printing. With the ink ribbon and paper properly installed in the printer, turn the power ON while holding down the Feed switch. Test printing will start and stop again automatically.

4. INSTALLATION OF INK RIBBON AND PAPER

4-1. Installation of Ink Ribbon

(1) Turn power off, lift the Printer Cover up and remove it. Note: Be careful not to touch the print head immediately after printing,

because it can get very hot.

Figure 4-1. Printer Cover Removal

(2) Unwind ribbon so that the spools are separated as shown in Figure 4-3.

Hold the ribbon taut as shown with the drive pins facing down and slide the

ribbon between the print head and the platen. While keeping the ribbon taut,

wrap one side around the black ribbon guide on the end of the platen and

drop one spool on the spool shaft. As you move the spool downwards, move

the detecting lever aside to allow the spool to drop into place. Make sure the

spool drive pins engage with the spool drive holes. As the spool drops into

place there will be a click. (3) While continuing to hold the ribbon taut, install the remaining ribbon spool

in a similar fashion. (4) Turn the spool that rotates freely to take up the ribbon slack.

4-3. Paper Insertion

4-3-1. Model DP8340F

(1) Cut the Roll Paper end straight and square. Hold the roll so that the paper

comes from the bottom. (2) Attach the Roll Paper to the Holders Paper by slipping one side of the roll

onto the Hub and pulling the other Hub out to allow the roll to slip in place. (3) Insert the paper evenly into the Paper Insertion Slot. (4) Turn the Power Switch “ON”, and press the FEED Button. The paper will

be fed into the unit.

Figure 4-5. Paper Insertion (2) [Model DP8340F]

– 10 –

4-3-2. Model DP8340S

1. Make a straight cut along the top of the paper, about 1/4 inch away from the

sprocket holes, (as shown in the figure). If there is perforation, cut the paper

on the perforation.

2. Insert the paper squarely into the paper insertion slot until the ALARM lamp

goes out. Then, hold down the FEED switch to advance the paper 8 lines,

and release the switch when 8-line feeding is completed.

If the paper is not fed straight during 8-line feeding, straighten the paper by

pulling it back slowly as you hold the paper release lever down. If a sprocket

hole is torn or enlarged, recut the paper and reinsert it as before.

3. After confirming that the paper has been fed in straight, feed the paper

continuously by holding the feed switch down.

4. Release the feed switch when the paper emerges through the paper outlet.

4-4. Paper Removal

Cut the paper close to the slot and use the feed button until paper has passed completely through the printer. Note: Do not try to remove the paper by hand as it could become crooked and

get jammed inside the printer.

LF (0A)

Print and line feed instruction The LF code causes the data in the line buffer to be printed,

followed by a single line feed. When the line buffer is empty, only the feed takes place.

CR (0D)

Print and line feed instruction Same function as of LF code.

However, when the DIP switch 2-4 is ON, the CR code becomes invalid.

SO (0E)

Expanded character instruction This code causes the printer to print expanded characters

twice as wide as the regular ones. This remains in effect until a DC4 code is received.
