1. Precaution Statements
1-1 Safety Precautions
1. Be sure that all of the built-in protective devices are replaced. Restore any missing protective shields.
2. When reinstalling the chassis and its assemblies, be sure to restore all protective devices including:
nonmetallic control knobs and compartment covers.
3. Make sure that there are no cabinet openings through which people –particularly children –might insert
fingers and contact dangerous voltages. Such openings include excessively wide cabinet ventilation slots
and improperly fitted covers and drawers.
4. Leakage Current Hot Check:
WARING: Do not use an isolation transformer during this test.
Use a leakage-current tester or a metering system that complies with American National Standards
Institute (ANSI C101.1, Leakage Current for Applications), and Underwriters Laboratories (UL Publications
UL1410, 59.7).
With the unit completely reassembled, plug the AC line cord directly into a 100VAC or 240VAC outlet of the
Adaptor.
With the unit’s AC switch first in the ON position and then OFF, measure the current between a known
Earth ground(metal water pipe, conduit, etc.) and all exposed metal part, including: metal cabinet, frame,
and screw-heads and printer. The current measure should not exceed 0.1 milliamp. Reverse the power-
plug prong in the AC outlet and repeat the test.
5. Design Alteration Warning:
Never alter or add to the mechanical or electrical design of the ECR. Unauthorized alterations might create
a safety hazard. Also any design changes or additions will void the manufacture’s warranty.
6. Components, parts and wiring that appear to have overhead or that are otherwise damaged should be
replaced with parts that meet the original specifications. Always determine the cause of damaged or
overheating and correct any potential hazards.
7. Observe the original lead dress, especially near the following areas: sharp edges, and especially the AC
and high voltage supplies. Always inspect for pinched, out-of-place, or frayed wiring.
Do not change the spacing between components and the printed circuit board. Check the AC power cord
for damage. Make sure that leads and components do not touch thermally hot parts.
8. Product Safety Notice:
Some electrical and mechanical parts have special safety-related characteristics, which might not be
obvious from visual inspection. These safety features and the protection they give might be lost if the
replacement component differs from the original-even if the replacement is rated for higher voltage,
wattage, etc.
Components that are critical for safety are indicated in the circuit diagram by shading, ( ) or ( ).
Use replacement components that have the same ratings, especially for flame resistance and dielectric
strength specifications. A replacement part that does not have the same safety characteristics as the
original might create shock, fire or other hazards.
CAUTION.
Danger of explosion if battery is incorrectly replaced.
Replace only with the same or equivalent type recommended by the manufacture.
Dispose of used batteries according to the manufacture’s instruction.

1-2 Servicing Precaution
WARNING 1: First read the Safety Precaution section of this manual. If some unforeseen
circumstance creates a conflict between the servicing and safety precautions, always
follow the safety precaution.
WARNING 2: An electrolytic capacitor installed with the wrong polarity might explode.
1. Always unplug the unit’s AC power cord from the AC power source or the Power Switch off before
attempting to:
(a) Remove or reinstall any component or assembly,
(b) Disconnect an electrical plug or connector,
(c) Connect a test component in parallel with an electrolytic capacitor.
2. Some components are raised above the printed circuit board for safety.
An insulation tube or tape is sometime used.
The internal wiring is sometimes clamped to prevent contact with thermally hot components.
Reinstall all such elements to their original position.
3. After servicing, always check that the screws, components and wiring have been correctly reinstalled.
Make sure that the portion around the serviced part has not been damaged.
4. Check the insulation between the blades of the AC plug and accessible conductive parts
(example: metal panels and input terminals).
5. Insulation Checking Procedure: Disconnect the power cord from the AC source and turn the power switch
ON. Connect an insulation resistance meter (500V) to the blades of the AC plug.
The insulation resistance between each blade of the AC plug and accessible conductive parts (see above)
should be greater than 1 mega-ohm.
6. Never defeat any of the B+ voltage interlock. Do not apply AC power to the unit (or any of its assemblies)
unless all solid-state heat sinks are correctly installed.
7. Always connect an instrument’s ground lead to the instrument chassis ground before connecting the
positive lead; always remove the instrument’s ground lead last.

1-3 Precaution for Electrostatically Sensitive Devices (ESDs)
1. Some semiconductor (solid state) devices are easily damaged by static electricity. Such components are
called Electrostatically Sensitive Devices (ESDs); examples include integrated circuits and some field-
effect transistors. The following techniques will reduce the occurrence of component damaged caused by
static electricity.
2. Immediately before handling any semiconductor components or assemblies, drain the electrostatic charge
from your body by touching a known earth ground. Alternatively, wear a discharging wrist-strap device.
(Be sure to remove it prior to applying power-this is an Electric shock precaution.)
3. After removing an ESD-equipped assembly, place it on a conductive surface such as aluminum foil to
prevent accumulation of electrostatic charge.
4. Do not use freon-propelled chemical. These can generate electrical charges that damage ESDs.
5. Use only a grounded-tip soldering iron when soldering or unsoldering ESDs.
6. Use only an anti-static solder removal device. Many solder removal devices are not rated as anti-static;
these can accumulate sufficient electrical charge to damage ESDs.
7. Do not remove a replacement ESD from its protective package until you are ready to install it.
Most replacement ESDs are packaged with leads that are electrically shorted together by conductive foam,
aluminum foil or other conductive materials.
8. Immediately before removing the protective material from the leads of a replacement ESD, touch the
protective material to the device will be installed.
9. Minimize body motions when handling unpacked replacement ESDs. Motions such as brushing clothes
together, or lifting a foot from a carpeted floor can generate enough static electricity to damaged an ESD.
1-4 Operational Precautions
1. The heating element of the printer mechanism’s thermal head and the driver IC are easily damaged.
Never allow these components to come into contact with metal or other hard objects.
2. Never touch the printer mechanism’s heating element with your hand. Doing so can damage the heating
element and affect proper operation.
3. The head and motor areas are very hot during and immediately after printing. Do not touch components
in these areas directly with your hand.
4. Do not use any paper other than these specified in this manual otherwise print head warranty and print
quality are affected adversely.
5. Thermal paper starts to color at around 70ºC. Take care to protect unused and printed thermal paper
against the affects of heat, light and characters on the paper to feed.
6. Take the roll paper out of the printer when you will not use the printer for a long time in a high temperature
and humidity environment.

2-2-10 Media Calibration
This printer has been designed to recognize the gaps with most print papers, but sometimes it may not
recognize the gap and keep feeding paper if a special type of paper is used. In this case, run Auto
Calibration function so that the printer can recognize the gap. BIXOLON printer provides various media
calibration methods in order to accommodate various special paper types.
1) About media calibration
• This function is for adjusting the sensitivity of the paper detection sensor for accurate
printing position control and measuring actual length of paper.
• Sensor sensitivity adjustment
- The purpose is to detect the identifier (gap/black mark/groove) of installed label
printer
• Paper length measurement
- Accurate length is required to rotate the printing orientation.
- The purpose is to detect the change of paper type.
2) When is media calibration required?
• When the printer is installed first time
• When the newly installed paper is a different paper type
• When printer position is not accurate or printer does not stop in the right position
3) How to perform media calibration
• The following four methods of media calibration can be used depending on the
conditions.
- Smart Media Detection
- Gap Sensor Auto Calibration Mode
- Black Mark Sensor Auto Calibration Mode
- Manual Calibration Mode
• Why are several calibration methods provided?
- Multiple labels should be scanned for media calibration and more accurate
sensitivity calibration can be performed when more labels are scanned.
- The number of labels to scan for sensor sensitivity adjustment depends on various
conditions such as label paper material, color, surface status, thickness, gap length,
pre-printed pattern, etc.
- Four different media calibration modes are provided for compromise between
prevention of excessive use of paper and accuracy of sensor sensitivity adjustment.
- Smart media detection mode that allows for adjustment of sensitivity with minimum
amount of scanning should be good enough for most cases with general labels.
- Try various methods in order of Smart Media Detection Gap Sensor Automatic
Calibration Black Mark Sensor Automatic Calibration Manual Calibration Mode.
