Maintenance and Troubleshooting 21
Vertical Line. A line vertically through the
entire print is cause by dust or debris on the
print head burn line or blown pixel on the
print head. See Section 3B for cleaning
instructions and 3C for print head replacement
instructions.
Horizontal Line. A horizontal line through
print is cause by a small bump on the slide.
This causes the entire print head to lift at this
point so the effect of the bump is extended to
the left and right of the bump. Low quality or
defective slides may be the cause.
Group of Spots. This may by cause by dust
particles on the slide. Keep the slide clean.
Store them in the blue slide cartridge at all
times. Avoid handling the slides. Do not
remove them from their shrink wrapping until
you will be inserting the slides into the blue
cartridge.
Light Printing. Light printing is caused by
insufficient heat or slides that are not thermal
printable (inkjet). You may be able to improve
quality by increasing the heat setting in the
Printer Preferences or the PTLab software.
Different manufacturers of slides may require
more or less heat. The minimum heat settings
possible that result in a good print should be
used. (Section 2B)
Random Missing Area (Print Surface Intact).
This is caused by a rough printable surface.
Low quality slides, defective slides or slides
that are not thermal printable (inkjet) may be
the cause.
