Wrinkles and scratches (cockle) on HP Coated and 
Heavyweight Coated Media.
Images may be damaged if prints are not handled with care, 
particularly when handling wide plots. This can happen when 
images are placed on top of one another and there is movement 
between them, causing friction and loss of ink from the surface if it 
is not completely attached. Also, if plots are rolled up, wrinkles can 
occur. To avoid this problem try the following:
n
Always handle plots with care.
n
Use of the Take-Up Reel eliminates handling and avoids 
wrinkles.
n
Use heavier media.
n
For Heavyweight Coated media, select faster print modes such as 
Heavyweight Coated (Economy) for Media selection, and/or 
Productivity Print mode.
n
If damage is slight, Lamination will help towhead’ defects.
n
Use of Fixative Sprays immediately after printing may protect the 
image.
Worm marks (cockle) on part of plots on paper based 
media
At high temperatures and under dry conditions, worm marks may 
occur on initial parts of plots when printing solid fill areas in 
medium tone colors. Try the following:
n
Advance the media manually by 15 mm.
n
Select Heavy Coated for Media setting.
n
Select Productivity mode to reduce ink density.
