1) Move the packing box to the working site and avoid strong shaking.
2) Disassemble the wooden packing box from top to bottom. Check whether the parts are complete or not
according to the packing list.
3) Lift the printer out by a forklift, and move it to the installation site.
4) Check if the printer is level.
5) Get rid of all the parts that stabilize the carriage holder, and install all the spare parts.
6) Move the carriage to the right of printer, then move back to the left manually. During this process, checks if
there are abnormal resistance and carefully inspect the belt & the encoder sensor are situated in proper
position
7) Ground the printer. The grounded voltage shouldn’t be more than 0.3V, and the grounded resistance should
be less than 3Ω.
8) Connect the USB cable between printer and computer. Check if the wires and data cables are plugged in
properly.
9) Install the output and the rip software.
10) Move the carriage to middle of printing platform, turn on the printer, let the carriage move to home position,
and keep your hand on the emergency button for turning off the printer if problem happens suddenly.
11) Send a file to print to test the condition of the printer.
12) Install printhead and dampers, connect the ink tube from damper to special solvent, and use auto clean
function to clean the printhead
13) Load ink bottle, and use auto clean function to suck the ink from ink bottle to printhead.
14) Print nozzle checking and observe the condition of printheads. It is recommended to keep a copy of the test
for reference in the future.
15) Printhead alignment.
16) Start to Print.

Chapter 7. Software Calibration
1. Nozzle checking: Print the nozzle checking to check the condition of the printhead.
Make sure to turn off the Eclosion (Feather) function before doing the alignment.
2. Vertical calibration: Observe the physical alignment of printheads.
（This step is not aligned well which will affect the following adjustment）
Align the physical vertical position of printhead.
The first pass line is the reference; observe whether the second pass line is perfectly aligned with the first
pass line. If not, then we need to adjust the carriage plate. There are 3 situations:
1) The two pass is perfectly aligned, no need to adjust:
2) The second is on the left side of the first pass:
Adjust method:
A. Loosen the 3 screws on the carriage plate:
B. Turn the screw clockwise:
First pass
Second pass
First pass
Second pass

11
3) The second is on the right side of the first pass:
Adjust method:
Note: Every time after the adjustment, before print another vertical calibration, it is required to tighten 3
screws on the carriage plate. Keep adjusting until the second pass is perfectly aligned with the first
pass.
3. Color offset: Color offset is to align all color in order to print good quality images.
Tip: Based on the "0" position, the color lines should totally matched with the Black line, if not, find the best one
showing on the printed out color offset, then input the corresponding values in the software. Note that values are
accumulated.
If the "0" position is not the perfect matching one, then we have to adjust the figure on the software. Go to Option
–Calibration –Color Offset
:
A. Loosen the 3 screws on the carriage plate:
B. Turn the screw anti-clockwise:
First pass
Second pass
Values are input here.

12
After input the value, print the alignment again. And observe if the "0" position is the best or not. If not, repeat the
above procedure until the best result come out.
4. Bi-Dir offset
Bi-Dir offset is to make sure there is no bi-difference while using different speed to print. Bi-Dir offset will be set
for different printing speed.
If the "0" position is not the perfect matching one, then we have to adjust the value on the software. Go to Option
–Calibration -Bi-Dir Offset
Repeat the test until the “0” is facing each other perfectly.
5. Step offset
The Step offset locates on Option –Calibration –Step Offset
:
To adjust the step offset, firstly adjust the Base Step, then the value of other pass will be calculated
automatically. And slightly adjustment is needed according to actual printing.
Input the value here. This
value is accumulated. Press
“Print”to print the test
pattern.

Input the offset
value
here.

13
Based on the "0" position, input the value which two line are perfectly overlapped. After input the value, test
again to check the result. The step value will be different according to different media.
Note: Turn off the Eclosion (Feather) function first while adjusting the step offset. Adjust to get the best
step value. Then test print to see whether there is banding on the image. If so, use the Eclosion (Feather)
function to reach your best image quality.
The adjustment of software has been completed now
Have to input +2.

Chapter 9. Maintenance
9.1 Normal Cleaning
Click Clean on the main interface of the software. There are two modes of cleaning, Standard and Depth.
Normally Standard mode is used.
9.2 Cleaning procedures for nozzle clogging:
1. Disconnect the tube connector for the tube from cartridge to the damper. Choose Standard clean mode the
suck out the ink in the damper. (2 times)
2. Use an extend tube to connect the damper, put the other side of the extend tube into the appointed Flush.
Choose Depth clean mode to clean the damper and the printhead at the same time.(3 times)
3. Take out the extend tube from the Flush, and keep it out in the air. Choose Depth clean mode to suck out the
Flush inside the damper and the printhead. After that connect the damper to the ink incoming tube and fill ink
again.
4. Test print.
9.3 Carriage Bearing and Steel Rail Maintenance
Due to the carriage slides on four steel plates and eight bearing, clean and lubricate four steel plates with grease
everyday.
Ⅰ. Wipe a thin layer of grease on steel plates to maintain cleanliness and grease everyday before and after
usage.
Ⅱ. Be aware of the smoothness of the carriage bearing.

17
9.4 Daily Maintenance
1. Print the nozzle checking before turn off the machine to make sure the printhead is in normal condition
2. Turn off the software, carriage go back to Home position automatically. Turn off the machine, the carriage stay
at the Home position.
3. Use sponge stick with appointed Flush to clean the cap and the wiper everyday before turning on the machine.
9.5 Short term shut down (3~7 days)
1. Disconnect the tube connector on top of the damper. Use Standard clean mode to empty the ink in the damper.
(2 times)
2. Use a extend tube to connect the damper to the appointed Flush.
Choose Depth clean mode to clean the damper and the printhead at the same time.(2 times)
3. Take out the extend tube from the Flush, and keep it out in the air. Choose Depth clean mode to empty the
Flush inside the damper and the printhead. Use the tube cover to seal the ink incoming tube, keep the cartridge
back to Home position and make sure the capping pad is perfectly capping the printhead.
9.6 Long term shut down (More than a week)
1. Print status before turn off the machine, make sure printhead in good condition..
2. Disconnect the tube connector on top of dampers, let the ink flow back to the cartridge.
3. Use the extend tube to connect them to the appointed Flush. Choose Depth clean mode to clean the damper
and the printhead at the same time. Clean one color at a time, use a cap to cover other three color channel.

18
4. Take out the extend tube from the Flush, and keep it out in the air. Choose Depth clean mode to empty the
Flush inside the damper and the printhead.
5. Take out the four tubes(K,C,M,Y) from the cartridge. Use the extend tube to connect them to flush.

19
Use a extend ink tube to connect the ink tube to ink pump
Choose “Ink Fill” mode at control panel, use ink pump to flush ink tube until it is clear. Then take out the tube from
the Flush, choose “Ink Fill” mode, empty the Flush inside the ink tube. Clean K,C,M,Y tube one by one
After cleaning, use cap and fresh warp to seal the ink tubes.

20
6. Take out four cartridges, use fresh wrap to seal the ink supply hole and keep the cartridges in the proper
place.
7. Keep the carriage back to Home position and make sure the cap is perfectly sealing the printhead.
