If you see the Terason entry, close all windows and start the Terason software. If you
still cannot see an image, contact Terason Technical Support.
Interference on the Scan
If the transducer or the Terason electronics envelope is too close to an electronic device,
such as your computer, you may see interference patterns in the scan image.
To resolve this problem, move the transducer and electronics away from all power
sources, including the laptop. If the cable from the laptop to the electronics is coiled or
looped, the laptop can interfere with the scan. Make sure the electronics is as far from the
laptop as the cable permits.
Printing Problems
The most common printing problems are:
• The printout is too light or too dark
• The printout is too small
Print Quality
The default printer settings should be sufficient to print a good image, although the type of
paper you put in the printer also affects image quality:
• Photo quality paper produces the best output, but is the most expensive
• Brochure paper produces good output, and costs less than photo quality paper
• Regular laser printer paper is the least expensive, but produces low-quality output
If the printer is low on ink, you may have to change the printer cartridge. refer to the
printer user manual for instructions.
If you must adjust the printer controls, refer to the user guide for the printer for
instructions on adjusting (usually to lighten) the output.
The Print Output is Too Small
You can enlarge the image display by pressing F11 (see
on page 75 for more information). This function key hides all other elements on
your desktop and uses the entire area for the image display. Print the image (press the
PrtScrn key), then press F11 again to restore the other elements.
Caution:
A printer installed within the patient environment may result in non-
conformance to safety standards. Use of non-medical grade peripherals
will result in non-compliance of safety and EMI standards. Non-
conformance to these standards can result in risks to the patient and
operator of this equipment.
