Horizon Imager
Loading ChromaVista Media
®
®
This technical brief explains how to load ChromaVista color
mediaandcolorribbonintheHorizonMulti-mediaDry
Imager.
Overview of ChromaVista Paper
and Film
ChromaVista color paper and film used with the Horizon
imager is prepackaged in factory-sealed, disposable
cassettes.
Each cassette contains a barcode that identifies the media
type and size, serial number, and sensitometry information.
The cassette’s lot number and “Use by” date are also printed
on the barcode label.
Cassettes can be loaded into any of the Horizon imager’s
three supply slots. However, the logical way to load cassettes
would be to insert the smaller ones at the top and the larger
ones at the bottom. This ensures that you can readily see
each cassette’s label and see whether there are sheets in any
of the receive trays.
Note: The color ribbon-related illustrations in the
Horizon Imager User’s Manual show a ribbon cartridge.
However, the cartridge is not yet available. For that
reason, this technical brief covers how to replace the
open spool version of the color ribbon, which is
available.

CAUTION: Do not refill a cassette. Do not tamper
with or remove the barcode label. The cassette’s
barcode information is essential for ensuring
diagnostic image quality. Compromising the cassette
in any way jeopardizes the quality and reliability of
the imager.

Opening a New Cassette
To open a new cassette, remove the clear wrapping from the
cassette. Use the pull strip to tear the clear wrapping open.
Inserting the Cassette
into a Supply Slot
1. Press the imager’s key, and wait until the imager
enters the Paused state.
2. Remove the cassette if one is currently in the supply slot
you want to use—lift the cassette up slightly and slide it
from the supply slot.
3. Insert the new cassette into the supply slot, with the
cassette label facing you and the barcode label to the left.
4. Slide the cassette into the supply slot until you feel the
cassette settle into the retaining detent.
5. Press the key to resume printing.
Seam
CAUTION: Do not remove the printed cassette cover;
it protects the media from dust and other
contaminants. Always hold and store the cassette with
theopensideuptopreventthesheetsfromfalling
out.
PAUSE
CAUTION: Do not remove or insert a cassette while a
sheet is being printed, or you could affect the image
quality of the printed sheet or cause a jam. Always
pause the imager first.
Note: Not all cassettes are the same length, so larger
cassettes will extend out further than shorter ones.

Brake-Off Leaders
ChromaVista color sheets have break-off leaders to allow
edge-to-edge printing.
◆ChromaVista color film has a break-off leader at the top
of the sheet.
◆ChromaVista color paper has a break-off leader at the
top and bottom of the sheet.
To remove the break-off leader, bend the leader at the
perforation line fully one way, then fully the other way. The
leader will break away from the sheet.
Loading a Color Ribbon
1. Press the imager’s key.
The Main Menu displays.
2. Select the Load/Remove Ribbon menu option.
The imager pauses and, after up to a minute to allow
internal components to cool, the top cover pops partially
open.
3. Lift the cover all the way open, and locate the ribbon
spools.
4. Remove the consumed ribbon spools (if applicable), as
showninthefollowingfigure.
Note: Always bend the leader to remove it—do not
tear it off—to avoid having stray pieces left on the
sheet.
MENU
WARNING: With the imager cover open, touch only
those internal components that are colored green.
Remove rings, ties, jewelry, and other items, and tie
back hair, so that they do not fall into or get caught
in the imager.

Note: Do not use the supply spool (rear) wheel to take
up ribbon slack. This would cause spent ribbon to be
reused.
PAUSE
CAUTION: Used ribbon retains the negative of the
color images that were printed using that ribbon. If
you are required to ensure patient confidentiality and
privacy, consumed ribbon should be destroyed.
Note: The only time you need to remove the ribbon is
if you are cleaning internal components or the ribbon
has been consumed. Otherwise, you can leave the
ribbon in the imager, even when printing to
DirectVista grayscale media.
