Check the following items in order. For even more detailed methods of dealing with problems, refer to
Troubleshooting in the printer's instruction manual.
(1) Check that the print head nozzles are not clogged.
- Print a nozzle print.
- If there are missing nozzles, register the nozzle number in SNM (smart nozzle mapping).
(2) Check that the media advance value is correct.
- Perform a media advance adjustment (by automatic advance adjustment or manual advance adjustment).
- When specifying the media advance value on the RIP side (media profile mode options), the specified value on
the RIP side has precedence over the adjustment value found by the adjustment on the printer side.
Check that the specified value on the RIP side is the adjustment value for that media.
* (For example, even for the same adhesive vinyl,) The optimal media advance value differs for each media product.
Always perform an adjustment for each media product.
(3) Try decreasing the heater temperatures.
For faintness or white lines, the cause may be that you are using a media product where the ink dots have
difficulty spreading. Try lowering the temperature of all three heaters by 5°C.
(When you change the heater temperature, change the media advance value again).
(4) Try increasing the heater temperatures.
For black lines, the cause may be that you are using a media product where the ink has difficulty drying.
Try raising the temperature of all three heaters by 5°C.
(When you change the heater temperature, change the media advance value again).
(5) Try printing in uni-direction.
When the cause is the difference of the order of ink being released going back and forth due to bi-directional
printing, this can be resolved with uni-directional printing.
(6) If you are using the Natural profile, try switching to the Vivid profile.
For solid filled portions in particular, printing is performed by restricting the ink when using the Natural profile,
so the filling of solids will tend to be weaker compared to the Vivid profile. Try switching to the Vivid profile.
(7) Switch to a higher quality print mode.
Switching to a higher quality print mode is effective for all of the causes listed above.
