7、Troubleshooting
7.1.Scales Crash
Boot up without any response
Reasons: a. bad contact between the power plug and socket.
b. the power cord is disconnected
c. Filtering group Fuse is disconnected.
d. Transformer is broken.
e. Motherboard is broken.
Solutions: use multimeter to check them one by one, use method of exclusion to find the
solution.
Boot up without any sound, No display, Backlit.
Reasons: the spark generated by the power plug impact the program.
Solutions: Replace the Motherboard, reset the number, and download all the files.
Boot up without any sound, display “Update”
Reasons: a. Program downloads error
b. misoperation during the downloading of the program (such as halfway power
outage)
Solutions:a. Reload the correct procedures.Setting IP (default is 192.168.1.87),when update by
ethernet.And if update by serial port input any number as the scale's ID
（the max baud
rate is 115200 ).
b. ditto
7.2. Print related issues
Print a blank label, paper orientation is normal.

Label Scale
7
Reasons: Setting label type error. Usually the label type computer download is D0, so label type
of label scale printing should be set D0. Or the printed label is blank.
Solutions: a. adjust the settings in following key order (on the scale)
[SETTING] Enter the system setting Press hotkey[ L ] Enter the select label
type（0：D0；1：D1）Press [PRN/Enter]
b. It’s also available to adjust software on computer. Open label scale, input serial
number of the scale. Change label type to D0in set function, then carry out function
set command.
Print half or a half label, paper orientation is abnormal.
Reasons: a. Set paper type detection error.
b. Printer rear photoelectric has slanting direction or is dust.
c. Photovoltaic panels is bad.
d. Photoelectric pair of printer rear photoelectric is bad.
Solutions: a. adjust the settings in following key order on the scale
[SETTING] Enter the system setting Press hotkey[S] Enter the select label type
（0：label；1：receipt 2: label, without recycle paper roll）Press [PRN/ENTER]
It’s also available to adjust software on computer. Open label scale , set paper type to “Label”
in set function, the pass the setting to error scale.
b. Check whether printer rear photoelectric has slanting direction or is dust.
c. If the problem still can’t be solved, consider changing photoelectric pair. It is
better to handle this step by professional person of our company.
Fuzzy print and it is not black enough
Reasons: a. printer head has not been fasten well.
b. Thermal head is dirty
c. Print density is too low.
Solutions: a. Re-fasten the printer head well.
b. Wipe the thermal head with a soft cloth glued alcohol gently
c. Increase print density
Print a label with half clear and half fuzzy or even blank.
Reasons: a. printer head has not been fasten well.
b. Thermal head is dirty
c. The print head deformation
Solutions: a. Re-fasten the printer head well.
b. Wipe the thermal head with a soft cloth glued alcohol gently
c. If the problem still can’t be solved by above method, then cause of the error is the
print head deformation, need to change printer. Bad printer should be handled by
professional person of our company.
Weird character show on label or character can’t be printed out(including Chinese and English)
Reasons: a. Haven’t download fonts or single-byte character.
b. Font conflict
Solutions: a. Re-download fonts (including single-byte and double-byte character.)
b. Re-select single-byte and double-byte fonts by files/option/label scale fonts, then
download Chinese and English fonts.

7.3. The key issues
Keys have been ringing, display is normal
Reasons: a. Line piece of key cause short circuit
b. Sharp object resist the key.
Solutions: a. Change line piece of the key
b. Move the sharp object.
Some keys do not ring
Reasons: a. Ribbon cable of the key hasn’t been inserted properly.
b. The conductive rubber of the key circuit board hasn’t been assemble properly.
c. The key is damaged.
Solutions: a . Check out key ribbon cable, re-insert properly.
b. Take out and re-assemble the key conductive rubber and the other positioning
rubber
c. If the problem still can’t be solved by above method, then maybe the key is
damaged, change it.
7.4. Weigh Problem
Weigh inaccurately
Reasons: a. The rubber mat supporting scale pan is touching the top cover.
b. Damp, module aging, or regional differences to make the weigh inaccurately.
c. The load cell damaged due to the overload.
d. Not adjust the Gravitational acceleration.
Solutions: a. Check the top cover is installed well, or not. If yes, reinstall load cell’s support
frame.
b. Leaning the Zero/Full weigh again. Replace the mainboard, AD board, even load
cell if the problem could not be solved.
c. Replace the load cell and support frame.
d. Adjust the Gravitational acceleration
PS: Generally, the scale should be returned back to our company due to the problems of AD
board and load cell.
Zero point instability
Reasons: a. Environmental impact, such as vibration, wind or strong magnetic interference….
b. Weighing electric circuit gets damp.
c. The wind resistance function has not opened.
d. The leveling mat is not leveling
Solutions: a. Exclude the interference factors
b. Replace the mainboard
c. Open the wind resistance function(set it in function set)
d. Adjust the leveling mat to be leveling.
e. If still not, return back the scale to our company
Unable to weigh
Reasons: Bad mainboard, bad AD board or bad load cell.
Solutions: a. Replace the mainboard
b. Check the AD board is OK, or not, return back to our company if this problem
could not be solved

7.5. Communication Problem
Unable to communicate
Reasons: a. Communication ports are set up incorrectly
b. The incorrect serial number of scale, or the incorrect IP address.
c. The incorrect connection of interface, or problem on Ethernet cable.
d. The error on power board or mainboard.
Solutions: a. Confirm the available communication ports
b. Confirm the same serial number in scale and, and same IP address in scale and
RLS.
c. Please replace mainboard or power board to confirm the error, if there are not the
problems mentioned above.
7.6. Display problem
No display or display but no characters
Reasons: a. Display pole is not installed well, result in poor contact with control board.

c. Display damage
Solutions：a. Install display pole, lock fixed bolt.
b. Change three-way plate or display pole
c. Change display pole
7.7. Other problems
Print paper difficultly, paper roll fixed.
Reasons：Maybe the mismatch between paper roll and shaft, or the wrong installation of shaft.
Solutions：It is better to return this printer to factory for reinstallation.
“KaKa” sound when printing, don’t feed paper(note: if appear this problem, please don't
press "print" button, otherwise may burn out main board)
Reasons：a. paper installation is not correct, cause paper jam.
b. paper receiving shaft jammed.
c. there is stuff between small gear and big gear.
Solutions：a. reinstall paper correctly
b. reinstall paper receiving shaft
c. check gear, remove stuff.
●Press PLU hotkey sometimes don't print, but the keyboard response
Reasons：a. the weight in scale instable
b. don’t download PLU data to scale
c. there is still paper in printer, don’t take away in time.
Solutions：a. Put scale on flat ground, and adjust the level Angle, keep it in a horizontal
position state.
b. download PLU data to scale from PC
c. take away label paper in time.
The failures listed above involving the handle of mainboard and sensors, the replacement of the
print head, printer, photocell, etc hardwares should return to the company and handled by the
professional staffs in principle.
Fault can’t be solved as above solutions, should return to the company and handled by
professional staffs.
