Printhead Crashes/Smears on High Density Prints Using Coated Media
High density prints can cause cockle mainly on HP Coated Media. This causes two main problems:
1. Cockling in the borders - Because the printer places too much ink on the Coated Media, the borders of the print become raised, causing the Printhead to crash against the media. To solve the problem, try the following:
- Change the paper margins to 15mm, either in the Front Panel or in the
Driver. If the customer is printing PostScript images, send them a PPD file
containing the extended margins of 15mm.
2. Cockling within the print - If the Printer places too much ink within the print, the media starts to ripple, causing the Printhead to smear against the media. To solve the problem, try the following:
- Check in the Front Panel if Ink Limiting is ON or OFF. If Ink Limiting is
OFF, turn it ON.
- Never use HP Coated Media for High Density prints. As a substitute use
HP Heavy Coated Media.
