Media

Always make sure that the customer is using the appropriate media

for the required image and that it is consistent with the software

application being used. To ensure color accuracy and print quality

performance of the Printer, only media types that have been

certified for the Printer should be used. Use of non-HP media or HP

media not certified for the printer may significantly reduce the color

and print quality of the required images. For details of HP media,

refer to the User’s Guide or the Media Guide for the HP

Designjet Printers.

NOTE To have accurate colors, the media settings must match the type

of media loaded in the printer.

If the customer is using non-HP media with HP drivers, the

colors in the required print may not be accurate. Advise the

customer to use HP media if they want to improve the accuracy

of the colors.

There are Smears or Scratching on the Printed Media

This problem can appear on paper-based coated media if a lot of ink

is printed quickly. The media cannot absorb the ink quickly enough

and becomes distorted. As the printheads move over the media, the

Printheads and the media come into contact with each other and the

printed image is smeared.

1 Press the Cancel key on the front panel; if you continue to print, the

paper may damage the printheads.

2 Cancel the print job from your computer application.

In order to obtain better results perform the following:



Use HP recommended media. If the image you are printing has

intense color, use HP Heavy Coated Paper

 Try to increase the print margins by relocating the image on the

page from the software application.

 If the customer is using ‘Media Saving Options’ from the

advanced section of the HP- GL/2 Driver, try disabling one or

both of the options ‘auto rotate’ and ‘inked area’.

If the above fails to solve the problem of smears and scratching,

change the media that the customer is using to a non-paper based

media such as HP High Gloss Photo Paper.
