Ensure the print head nozzles are not blocked, but no ink come out while printing; the problem might be caused by broken main board which might be mainly caused by that the print head is not installed correctly or the cables connected incorrectly which caused short circuit happen.
Solution:
Check the print head and its cables and see if need to replace any part. then change the mainboard
Pay more attention when installing the mainboard

9. The print head moves out in high speed, crash towards left side when getting online.
Malfunction analysis:
The encoder strip is dirty, its sensor can’t read the signal; or the friction is increasing.
Solution:
First check the stainless steel sliding way(oriented sliding way) and oriented steel piece; ensure move smoothly.
Check the encoder strip and its sensor; ensure no any damage; check the print head cable.

Attention:
After solving this malfunction, a print head alignment (on the flatbed printer driver) is needed.
