Smudging Issues
Smudging occurs when the wet image, on the media, makes contact with something (most commonly the printhead
or upper exit rollers) before it is dry. This issue will also increase the chance for scuff marks.
Here is an example of “smudging” that occurred when an area of this page, with a wet image, made contact with the
printhead or something else as it exits printer.
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 Print Platen & Drip Tray are properly installed.
•
Make sure media is as flat as possible and folds are as tight 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 S Series Driver.
If you are using “Over Speed” feature, try turning this off.
•
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.
