Color consistency problems
• Some paper may discolor or change with age. Check that your paper is fresh and has been stored correctly.
• If the environmental conditions you are printing in change rapidly, you may see changes in the color consistency. By reducing the time the print stays in extreme environmental conditions after being printed 
(especially very high humidity) you can reduce the color consistency problems.
• There may be color changes between images printed on your printer and other types...

Color accuracy configuration

Additional color accuracy information
The means of accurately managing the colors printed by your printer vary with the software application and driver 
being used. Refer to the following documentation:
• On-line documentation in the drivers shipped with your printer.
• If you cannot find any reason for the discrepancy, before getting help, find out for which CMYK printer inks the colors have been specified.
 

Ink supply problemsMost of the problems that you could encounter when working with HP ink supplies can be solved with guidance 
from the front panel. The only exception to this is the Unknown printhead error

supplied in  Message descriptions

Printhead problems after replacementIf, after replacing the printheads, the printer complains about wrong or missing printheads, perform the following

Unknown printhead errorAn unknown printhead error occurs when the one of the printheads is causing a 
problem but the system cannot detect which one it is. Whenever this happens the 
front panel displays this error message. The number of printheads with unknown 
errors will either be all the color printheads or all the printheads.

PaperAlways make sure that you are using the appropriate paper for your image and that it is consistent with your 
software application. To ensure color accuracy and print-quality performance of the printer, use only paper types 
that have been certified for your printer.
Use of non-HP paper or HP paper not certified for your printer may significantly reduce the color and print quality 
of your images. For details of HP paper, see Paper types
.
 

Clearing a paper jamIf the front panel displays this message:
There is probably paper jammed in the printer. Paper jams can have 
various causes:
• The paper is too thick or too thin for the printer, or is otherwise not supported.
• The paper is creased, misaligned, or bubbled.
• Too much ink is being placed on the paper causing it to cockle or bubble.
• The end of the roll of paper is glued to the core and won’t advance further.
• Pieces of paper or paper powder are clogging up the cutter guide or other...

Removing jammed paper
1. Open the window.
2. Switch the printer off at the front.
3. If necessary, carefully move the printhead carriage out of the way—if possible all the way to the enclosed area on the left or the right. Which way you are able to move it depends on where the paper is jammed.CAUTION:
When moving the printhead carriage, touch only the black plastic parts.
4. If necessary, carefully move the paper cutter out of the way to the left,  or to the right depending on where the paper is jammed...
