Notes

1) Follow the steps in this manual hereafter during maintenance.

2) Make sure that the printer and the computer are turned off before plugging the communication cable,

changing print head or doing maintenance to the printer.

3) Take anti- static measures, when replace print head or other electronic components.

4) Time between turning on and turning off the printer is no less than 20 seconds.

5) Do not allow the printer to print when there is no paper loading, otherwise the print head and platen

roller will be damaged.

6) Set the printing darkness in a lower grade as long as the print quality is acceptable. This will help to

keep the print head durable.

1 Printer characteristics

1.1 Function

 High speed printing

The print speed is 150mm/s;

 High reliability

The lifetime of cutter is not less than 1 million times (60g recommended paper, the paper type is OJI

PD15/PD150R, room temperature 25°C);

The lifetime of printhead is not less than 100km (12.5% duty ratio, 60g recommended paper, paper

type is OJI FD210, room temperature 25°C);

MCBF 37,000,000 lines.

 Single paper feeding path

This product is configured with one straight paper feeding path.

 Adapt to single-type width paper

This product can adapt to paper with a width of 79.5±0.5 mm;

 Semi-automatic paper feeding

This product has semi-automatic paper feeding function

 Easy to maintain

The product adopts unique patented technology—platen roller slips away from the print head and it is

easy to clean the print head and clear the errors. If the cutter can’t reset, the user still can open the

platen and stationary blade at the same time without damaging the movable blade.

7) Recommended paper:

Paper type Manufacturer

FD210 OJI Paper CO., LTD.

PD150 OJI Paper CO., LTD.

PD150R OJI Paper CO., LTD.

Table 1.3.5 Recommended paper

Caution:

 Please use the recommended paper or its equivalents. Using the paper of low quality might affect the

print quality and shorten the lifetime of print head;

 Do not stick paper onto the paper roll core shaft;

 If the paper is contaminated by chemical or oil, it may discolor at the polluted spot or have poor printing

effect;

 Do not rub the thermal side of paper with hard objects, otherwise the printing contents may be not

clear.

 When the environment temperature goes up to 70℃, paper will discolor. Thus don’t use or store paper

under high temperature, high humidity and strong light conditions, etc.;

1.3.6 Lable paper specification

Except for the requirements of standard paper, the mark paper should aslo meet the following

requirements:

1) Mark position

The mark with the paper width is more than 79mm can be selected to be at the left, middle and right

positions of the thermal / non-thermal layer, as shown in Fig.1.2.6. Make sure that the marks on both sides

are completely covered by the mark sensor (distance from the mark sensors at both sides to the center line

of paper is 38.2mm).

2) When select the mark, the following parameters are recommended:

 L1 makr height: 8mm≤L1≤Paper width

 L2 makr height: 4mm≤L2≤8mm

3) The mark’s reflectivity should be less than 10%, and the reflectivity of the other parts along the paper

feeding direction within the width of the mark should be more than 75%.

Caution:

 Due to the jitter during paper feeding and the difference in paper parameters, the positioning of mark

may have an error of ±1 mm;
