Smudging:
Here is an example of “smudging” that occurred when an area of this page, with a wet image, made contact
with the printhead.
Note: There are also scuff marks in this example. As mentioned previously; smudging will increase the
chance for scuff marks; by deposition ink onto other areas of the printhead.
Possible Solutions to Reduce Smudging:
•
Check to be sure the “Head Media Guide” is properly installed and clean.
•
Make sure media is as flat as possible.
•
If possible; rotate the media and image 90, 270 or 180 degrees. Sometimes the direction of feed
and the mechanics of how the media is driven through the printer can have an effect.
•
Reduce the amount of ink being sprayed onto the media by setting the print quality to “Normal”.
Spraying less ink will improve the drying time.
•
Reduce the print speed to provide more drying time. If you are already printing in Normal Print
Quality, you can select (check) the “half speed” box; located under the Print Quality selection in
the M Series Driver.
•
Use a more inkjet suitable media.
NOTICE! It is OK to run the “Quick Clean Printhead” routine once, to see if this has any effect on
improving this issue. However, if it doesn’t help, you shouldn’t repeat this process or use a higher level
cleaning routine. Over-use of the “…Clean Printhead” routines will normally increase this issue, because
the wiper roller will become more saturated with ink with each cleaning routine; if done too frequently. An
over-saturated wiper roller will leave more ink behind on the printhead.
