2.
Ensure the Media Edge holders are correctly installed extract from user’s guide, p25:
The correct position is illustrated below, where (1) indicates the edge of the substrate. The substrate
should be free to move, and should not touch the ends of the edge holder.
The temperature, tension, vacuum all have an impact on the movement of the substrate, which can be a
factor when troubleshooting wrinkles. Ensure that the preset for the substrate has been correctly
configured, check the steps in the User’s Guide under the heading ‘Create a new preset’.
In the Maintenance and Troubleshooting guide, there is a section dedicated to troubleshooting wrinkles
on the substrate. The following is further information on this issue.
1.
Wrinkles in the middle of the substrate
a.
LX800 only: Remove the diverter (the bow shape of the diverter, can make the substrate
move towards the middle).
b.
Reduce as much as possible the temperature (which may require an increase in the number of
passes to ensure a correct level of curing),
c.
Increase tension of the substrate.
2.
Substrate becoming loose at the sides, while remaining in tension in the center (can occur with
paper based substrates such as the HP photorealistic for example):
a.
LX800 only: Add a diverter (with the bow shape, this will maintain the tension in both the
center and the sides).
CAUTION:
Incorrectly positioned edge holders could severely damage the printheads and carriage.
