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:
|
 |
|
-Try using Heavy Weight Coated Media instead of
Coated Media.
-Change the paper margins to "Extended" in the Printer Setup
menu/Page Format/Margins or in the Driver. If the customer is printing
PostScript images, send them a PPD file containing the extended margins.
-Use the Deflectors.
-Upgrade the Firmware (See System
Maintenance). |
|
|
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: |
|
|
|
|
-Never use HP Coated Media for High Density prints.
As a substitute use HP Heavy Weight Coated or Heavy Weight Coated
(Economy) Media. |
