3D. Troubleshooting Print Quality
Print Quality problems are usually caused by debris or flaws on the printable surface of the slide. Use the chart
below to diagnose quality problems.

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.
Random Missing Area (Printable Surface Missing). If the printable surface is
missing or scratched off, the printer cannot print in these areas. Low quality
slides, defective slides or mishandling of slides may be the cause of this
problem.
Rounding at the leading edge. Rounding at the leading edge of any new
color on a slide is typically caused by low quality slides or slides that are not
thermal printable (inkjet).
