COMMON TROUBLESHOOTING AND ANALYSIS UV PRINTER |
||
|
Nozzle |
The check appears with empty spaces |
-Clean the heads by purging -Increase the value of negative pressure 0.5 -Modify the temperature values |
|
|
||
|
|
||
|

-Check primary tanks |
|
-Check open valves -Check flow sensor of secondary tanks -Check the positive pressure value at 18 |
||
|
|
||
|
|
||
|

|
|
||
|
|
||
|
Z axis |

|
|
||
|
|
||
|
Print |
Bidirectional with low resolution |
-Verify bidirectional calibration -Modify the bidirectional value during printing -Check height of 2mm and do calibration on the height of the material |
|
|
||
|
|
||
|
Print |
Opaque colors |
-Increase the percentage of ink in RIPrint (Up to 60%) -Modify the temperature and voltage values |
|
|
||
|

|
|
||
|
Print |
The check generates a thick stripe of wrong color |
-Reconnect the data tapes to the processing cards |
|
Print |
The print is scratched and does not seem to dry |
-Clean and verify check. -Variate and test print with Normal and Depth |
|
Print |
Color shading |
-Tune the color calibration in decimal values. |
|
