III. Operating Process
1. Set temperature required
Turn on power switch, temperature
light is ON. The digital display shows
.
Press button, the light is
on (C denotes Celsius). Press
arrows “△” or “▽” to select “℃” or
“℉” (F denotes Fahrenheit)
according to your habits.
Press button, the temp light
is on. Select with arrows the
temperature according to different
transfer material (Normally
180℃~200℃)
2. Set time required
Hot Port
Cold Port
Press button after temperature
setting and the time light is
on. Select with arrows the time
according to different transfer
material.
Press button after time setting;
the display shows the temperature
starts to rise. “CD-L” shows the time
counting down during your transfer.
Note: There are two small port in
front side of the digital display.
If the real temperature is lower than
digital controller shown, you can
adjust the “hot port”; Clockwise to
raise temperature; anticlockwise to
reduce temperature.
3. Printing methods
Step 1: Make sure the cord is connected well to the wall socket. Place the object (i.e. T-shirt) on press bed, and
transfer paper with images facing down the object, adjust pressure to your requirement, and turn on the power.
Step 2: Set the temperature and time required, then temperature starts to rise.
Step 3: When the temperature rises to the setting temperature, the buzzer sends out sounds; then close down heat
platen (meantime the sounds stop) and starts to transfer.
Step 4: Then the time counter is on, once time is up, the upper heat platen will auto open automatically.
Step: Consult the Transfer Paper instructions on whether to peel cold or hot, Here are suggested Pressing time
guidelines for different transfer paper.

Ink-Jet Transfer Paper (fabric) 14-18 seconds
Laser Copier/Printer Transfer Paper (fabric) 18-25 seconds
Sublimation Transfers (onto Fabrics) 25-30 seconds
Sublimation Transfers (onto FR-Plastic/Woods) 60-70 seconds
5. Recommendations:
1) Ceramic tile transfer: (Mugs & Plates transfer is similar)
Set temperature: 180 .℃
Set time: 15 seconds
2) T-shirt transfer:
Set temperature: 180 .℃
Set time: (chemical fiber use for sublimation transfer paper: 30-50seconds; pure cotton use for T-shirt
transfer paper: 10-20seconds)
3) Plastic iPhone 4/4s case transfer:
Set temperature: 180℃
Set time: (Aluminum sheet:45 seconds;Polyester Cloth: 60 seconds)
4) Metal Keyring transfer: (Metal Mirror transfer is similar)
Set temperature: 180 .℃
Set time: 45 seconds
5) Polymer Keyring transfer:
Set temperature: 180 .℃
Set time: 90 seconds
NOTE:
1) Please switch off the machine and unplug the power cord when the machine is not in use.
2) The heat platen will cool down to the room temperature, if heat press stays un-use for more than 30 minutes.
3) The heat-releasing fan will automatically starts when the temperature of heat platen reaches 80 degree C (176
degree F). It helps to reduce the temperature of electrical parts and prolong the service life of them.
4) For better maintenance of heat press, the maximum setting temperature is 210 degrees C (410 degrees F).
5) To avoid re-heating the first transfer when printing double sided T-Shirts, insert a sheet of cardboard in between
the shirt, adjust the height to less pressure, then press.
6) Heat platen may pivot slightly back and forth rotationally. This is due to movement allowance within the clamp
assembly, and is normal.

V. Maintenance
1. No action after turn on the machine
1). Check the plug whether it connects well or whether it is broken.
2). Check the power switch or digital controller whether it is broken.
3). Check the fuse whether it has been burnt out.
4). Indicating light is on, but no display on screen, check the 5 cable of Railway transformer. If it’s loosening,
showing the problem is poor connection. If they connects well, showing that the Transformer is faulty.
2. The display screen are working well, but no temperature increasing on the heat platen.
1). Check whether the thermocouple of the heat platen touches well. If the thermocouple is loose, the display will
show 255 and machine keeps beeping.
2). Check if the indicating light of solid-state relay is on, if not, check if the relay or digital controller is broken.
3). If you already changed the new solid-state relay but the heat platen still can’t heating up, check if the heat platen
is faulty or the heat platen’s power cable is loose, need to change by new heat platen.
3. The heat platen works well, but suddenly the display screen show 255℃.
1). Check whether the thermocouple of the heat platen touches well.
2). If the thermocouple touches well but still show 255℃, then it is faulty.
4. The machine is heating during 0~180℃, but display number jumps to above 200℃ or 300℃ suddenly, or
the numbers on display jumps irregularly.
1). Check whether the thermocouple of the heat platen touches well.
2). If the thermocouple is good, It shows that the program of digital controller is broken, which namely IC or is
broken, need to change by new controller.
5. The temperature is out of control: Set 180℃，but the actual temperature is above 200℃。
1). It means the solid-state relay is broken, out of control, need to change the relay.
2). Or the digital controller is faulty and it keeps conveying electric to relay, need to change controller.
6. The setting temp and time becomes abnormal after exchange the heat platen
1). Please reset the temp and time according the operation process manual.
7. Other notice
1). In order to prolong the machine service life, please add the lubrication oil regularly on the joints.
2). In order to keep the heat platen's good transfer effect, you need to protect the heat platen carefully whenever
you are using it or not.
3). Please keep the machine in dry place.
4). If you are not able to solve the electrical parts problem, please kindly contact the supplier and get technical
support.
IV. Trouble shooting for transfer print quality
1. If the print color is pale: the temperature is too low / the pressure is not correct / or not pressed long enough.
2. If the print color is too brown or the transfer paper is almost burnt: reduce the setting temperature
2. If the print is blurring: too much transfer time causes proliferation.
3. If print color is different/ partial transfer effect is not good enough: the pressure is not enough / or not pressed
long enough / or poor quality transfer paper.
4. If transfer paper stick to the object after transfer: the temperature is too high/ or poor quality printing ink.
