Troubleshooting and Maintenance 63
9. Source File Image Mode. The image mode of the source file may
be set to RGB instead of CMYK. This can cause the color
matching to be off. Change the image mode of the original file,
resave and reprint.
10. Copper Contacts. Clean the copper contacts on the back of the
print carriage and the contacts on the print head with rubbing
alcohol.
11. Image Resolution (DPI). Try another Image. Perhaps the
resolution of the current image is not sufficient for a quality
print. Many graphics suitable for viewing onscreen have a DPI
of 72. This is the minimum DPI for proper screen display.
However, if you print this image it will look blurry and
pixilated. 72 is a typical DPI for images or graphics saved from
web sites. We recommend a 300 dpi image.
12. Cable. Try another USB cable. Make sure that it is less than 2
Meters (6ft) long. Faulty cables or cables that are too long
interrupt communications which can result in print quality
issues.
13. Saturation. If ink is bleeding, decrease saturation in driver
preferences.
14. Change the Print Head. If print nozzles of certain colors are still
clogged after repeated cleanings it may be time to replace the
print head. See Section 5G.
C. COLOR MATCHING AND DESIGN TIPS
Whether you contract your graphic design or do it yourself, these
guidelines will help you get the best quality labels out of your
LX900e.
1. Image Size/Shape. The image size should correspond with the
size of the label you will be printing. Note: If the source image is
smaller and must be enlarged to fill the entire label space, this
will affect the DPI. A 50.8mm x 50.8mm (2" x 2") 300 dpi label
blown up to fit on a 101.6mm x 101.6mm (4" x 4") label would
have an effective dpi of 75. This would not be a sufficient
resolution. See item 2.
