HP 5000 manual Worm marks cockle on part of plots on paper based media

Troubleshooting

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:

νAlways handle plots with care.

νUse of the Take-Up Reel eliminates handling and avoids wrinkles.

νUse heavier media.

νFor Heavyweight Coated media, select faster print modes such as Heavyweight Coated (Economy) for Media selection, and/or Productivity Print mode.

νIf damage is slight, Lamination will help towhead’ defects.

νUse of Fixative Sprays immediately after printing may protect the image.

νAdvance the media manually by 15 mm.
