8 .Machine maintenance:

1. Print head maintenance:

① There is a small board inside the print head, for which connect with the printhead cable. Please keep
the connection port dry, if there's any liquid on the conection port,turn off the machine immediately and
and take off the cable to clean it. Or it might make the print head & print head to be burnt;
② The print head connects to the small board port closly, so should not disconnect and reconnect
frequently. After long time using, should check if there's any damage on the print head cable end, if so,
change the cable;
③ If don't use the machine to production, should at least print nozzle test or a small sample everyday if
possible. If the nozzle test has problem, fix it. If need to leave the machine for over 3 days, put 3-5
drops of uv cleaner on the cap top and seal with the machine to keep it moisture.
④ Should fill less inks into the ink tank each time, half ink tank is OK. Once open the ink bottle,
should use up the ink within 3 months, or the ink will be expired and will effect the print quality or
might block the print head. Suggest to stir the ink in the ink tank by using clean stick for every few
days(one week). Open the white ink stirrer when printing.
⑤ The print height between the print head and the printing material should be 2-3mm, must check the
print height before printing every-time to avoid the crash of the print head.
⑥ Clean the cart for every few days in case too much waste inks there.
⑦ Don't print the reflective materials, or it'll make the print head to be blocked.
2. Capping system maintenance: There will have the ink drops after print head cleaning, need to clean
the waste ink once it happens by using alcohol.
3. Encoder strip maintenance: The encoder strip is use to guide the movement of the cart, if the encoder
strip has scratches on it or out of the bars, the encoder strip sensor might not be able to read the encoder
strip, then it'll effect the movement of the cart. So, need to check the encoder strip every few days(one
week), to see if the it is inside the bars and in the middle of the encoder strip sensor, if there's any
scratches and dust on it. Can use the alcohol to clean the dust. If the encoder strip has problem, replace it.
4. Guideline maintenance: There has the cart guideline and the plate table guidelines, there are lubricating oil on
the guidelines and sliders, need to fill the oil on them after long time to avoid the corrosion and oxidation. If there
are too much dust and dirty, then clean by alcohol first, then fill the oil.
5.Damper: Suggest to change for every 3 months.
1. Cap top: Suggest to change for every 3 months.
