Horizon Imager
Software
®
Version 1.6.0 Release Notes
◆
Blue and Clear DirectVista Film calibration now works
correctly. Previously, an imager that had been calibrated
first with blue film would print too dark on clear film,
and an imager that had been calibrated first with clear
film would print too light with blue film (see Product
Bulletin 103, 903-001-003).
Horizon Version 1.6.0 Software offers many product
improvements as detailed below.
◆
Important Note: Once Version 1.6.0 Software is installed
onto a Horizon Imager it will not operate properly with
any earlier version, such as Version 1.4.1. Do not install an
earlier software version after installing 1.6.0!
Print counter. Imager now stores the total number of
ChromaVista and DirectVista sheets printed. This
information is currently accessible only by a factory
technician.
◆
Invalid network-gateway handling corrected.
Previously, when upgrading a system that had an invalid
network gateway configured (e.g., did not match the
network portion of the IP address), the system would
reset all network settings to default values. Now it resets
only the gateway to the default value. (Obscure)
◆
Prevent shutdown when print head not parked. To
safely move the imager and avoid permanent damage,
the print head needs to be in the parked position (all the
way back). This is done automatically by performing a
soft power-off using the power key on the Control Panel.
If the receive trays are removed or the top cover is open,
a safety interlock will prevent the print head from
moving to the parked position. If a soft power-off is
initiated and the print head cannot park, the power-off
will be cancelled, the imager will beep, and a fault
message will be displayed.
◆
Support for long FTP filenames and for filenames
containing spaces or special characters. FTP connections
now properly support file names containing the
characters ‘@#$%^&()-+’. Also, filename length
maximum has been increased to 255 characters.
◆
Corrected several “memory leaks” and “performance
leaks.”
(Differences Since Versions 1.5.0 and 1.5.2)
Summary
New Feature List
◆
◆
◆
Added capability for OEM-specific system Job Settings
files. This release adds a system Job Settings file called
SYNGOFILM which forces the following settings:
Gamma = 1.0
Contrast = 0
LUT = Linear
Saturation = 0
MCM = 0
Decimation warn = On
Support for multiple IP address. The most efficient way
to take advantage of Horizon’s multiple media features is
to define multiple “virtual printers” on a host system
with the same IP address but different media settings or
DICOM AE titles. Some host systems will not allow
multiple printers to be set up with the same IP address. A
single Horizon imager can now be configured with
multiple IP addresses to overcome this limitation. See
Product Bulletin 104 (903-001-004) for details.
Verbose logging for print jobs. As jobs are added to the
print queue, all information on image, sheet, and job
parameters are displayed in the log files.
◆
Previously, system memory was slowly consumed
and performance slowly degraded, eventually
causing the imager to stop queuing jobs (corrected by
rebooting) after several hundred prints. This has been
corrected.
◆
A “memory watchdog” has been added to monitor
system memory and take corrective measures if
required.
Defects Repaired
◆
Improved color registration on ChromaVista ® Paper
prints. The three color planes on ChromaVista prints are
now more precisely aligned producing consistently
sharper looking prints.

◆
An automatic file system cleanup now occurs every
three weeks. Since a reboot is required for this
operation, the user is reminded, via a system alert, to
reboot when appropriate.
◆
Corrected banding problem with test prints. The
“Mixed Patterns” test print had horizontal and vertical
gray wedges that contained visible banding. This has
been corrected.
◆
Correct several log file inefficiencies which were
slowing system performance.
◆
Corrected problem with dropped LPR images.
Previously, in certain rare circumstances, image files
transferred via LPR were processed before the transfer
was completed. This caused a blank cell with the caption
“Image Processing Failed” to be printed instead of the
image. (Obscure)
◆
Cassette barcode reader window cleaning position
corrected. Previously, the barcode reader was not
positioned correctly. (Obscure)
◆
Improved safety interlock for cassette barcode reader.
The laser is now immediately turned off if the scanning
mirror movement is not detected.
◆
Corrected problem with losing date and time.
Previously, under rare circumstances, it was possible for
the system’s real time clock to reset to an incorrect date
and time. (Obscure)
◆
Automatic downgrading of Control Panel firmware
supported. Previously, the automated software
installation process supported upgrading but not
downgrading. (Obscure)
◆
Eliminated border fill for A4 and 14x17 DirectVista
Paper. Previously, border fill could be turned on for this
media which printed off the side of the sheet causing
buildup on the print head.
◆
Viewable custom User Settings. Custom User Settings
can now be viewed by logging into the imager and
typing the command stat user where user is the user
ID used to create the User Settings. (Obscure)
◆
Corrected rare system lockup. Previously, in rare
circumstances, it was possible for an imager to “lock up”
requiring the power to be cycled. (Obscure)
◆
Cassette barcode properly read after booting with top
cover open, and subsequently closing top cover.
Previously this operation would require the cassette to be
removed and reinserted. (Obscure)
◆
Disconnected smart card reader no longer causes the
imager to continuously reboot. Imager will now report
an invalid smart card in such circumstances. (Obscure)
◆
Loading system configurations from a zip disk no
longer causes a double reboot.
◆
Added automatic shutdown when internal temperature
limits exceeded. CPU temperature above 70 degrees C or
below 0 degrees C will cause a controlled shutdown,
completing a print in progress. CPU temperature above
74 degrees C will cause an immediate shutdown.
◆
◆
◆
Eliminated extraneous pick-tire movement. Previously,
the pick tires would spin in cassette #1 after the last sheet
of 14x17 film was picked. (Obscure)
Corrected defects with supply cassette selection.
Previously, the imager did not continue with the current
supply cassette after a reboot, but instead would select
the first available cassette. Now it will continue with the
same cassette, as long as it is still loaded. Also, if a
cassette is empty, and another cassette with the same
media is available, the imager will correctly switch to the
next cassette even if the previous empty cassette is
replaced before the next sheet is printed. (Obscure)
Software support for improved side-edge sensors.
Newer imagers have improved side-edge sensors which
increase the range of side-edge detection. This eliminated
a problem where the position of the outer black filmborder was incorrect in some cases. Such imagers can be
identified a “CNFG.” number of 002.22 or higher on the
back of the unit. Support for this hardware was present
in version 1.5.2, but many customers will upgrade
directly to 1.6.0 from 1.5.0 or 1.4.1.
Defects Improved
◆
Faster startup and shutdown times. Startup time is
approximately 20 seconds faster than with 1.5.2 software.
Shutdown time is approximately 12 seconds faster.
◆
Faster printing. Time to first print for a typical 14x17 film
job is approximately 11 seconds faster than with 1.5.2
software.
◆
DICOM Interface Improvements.
◆
DICOM format “STANDARD\1,1” is now handled
correctly. Previously, images using this format were
padded with a border causing undesirable
downscaling.
◆
Allow a DICOM photometric interpretation of “RGB”
for Grayscale Image Boxes. The GE Entegra system
(which is based on ISG/Cedera Hardcopy Server
software) specifies a photometric interpretation of
“RGB” for grayscale images. In this case, the value is
disregarded, and the default value of
“MONOCHROME2” is substituted. (Obscure)

◆
DICOM photometric interpretation of
“MONOCHROME1” is now handled correctly.
Grayscale images that specify this parameter are now
properly printed with reverse polarity. (Obscure)
◆
DICOM odd image sizes are now properly handled.
Previously, the imager would not print DICOM
images with an odd number of pixels. (Obscure)
◆
◆
◆
Images are now left unscaled when the DICOM
scaling type is specified as “none.” Previously, a
scaling type of “none” caused the default scaling
setting to be used. For example, a 512x512 image sent
with a scaling type of “none” will not be printed as
large as possible, but instead will be printed on the
sheet with 512x512 imager pixels.
Incorrect DICOM context ID is now permitted.
Certain systems (for example, Aloka, Toshiba, and
Siemens ultrasound) have been found to use
Presentation Context IDs in a manner which is
incompatible with Horizon, when sending color print
jobs via DICOM. A grayscale film box is created, and
then a color image box is sent within its scope, but the
N-SET of the image actually uses two context IDs
(one for the Color PMM and one for Grayscale PMM).
This caused a failure in the Horizon software, since
the color image box being sent doesn't really exist as
identified. The actual problem is that the FilmSession
and FilmBox are N-CREATED in one context, and the
N-SET of the images is done in another context.
Horizon now correctly prints in this situation.
(Obscure)
PostScript Interface Improvements. These
improvements are required for proper operation with
Vital Images, Toshiba, GE Advantage Windows, and
Siemens Magicview workstations. They may also be
required for other workstations which do not use
Codonics Windows print drivers.
◆
PostScript PPD files now contain proper release
version string. (Obscure)
◆
Windows XP driver installer now properly queries
for a Windows XP CD. Previously, the installer
queried for a Windows 2000 CD.
◆
The PostScript driver uninstaller for Windows NT,
2000, and XP now correctly removes all Horizon
PostScript driver files when using the Start->Settings>Printers menu. Previously, the driver could not be
uninstalled which interfered with installing newer
versions of the driver.
◆
Windows Network Protocol (SMB) print interface is
now supported for Windows 98 and ME. This
eliminates the need for third party LPR clients for
PostScript printing with these operating systems.
◆
◆
PostScript processing now properly uses Job Settings
for pagesize (imagable area) definition. Previously, if
the pagesize was not specified within the PostScript
job, the sheet would be always be rendered at
“Letter” size regardless of the media size selected via
Job Settings.
◆
PostScript processing no longer requires the pagesize
to match the pagesize of the selected media.
Previously, jobs that had a pagesize mismatch would
be rejected. Note: Image data that is rendered outside
the imagable area of the selected media will be
cropped.
◆
PostScript jobs which are created without Codonics
Windows drivers and are sent to logical device 7 will
have all unmarked space cropped to allow for
maximum image size. Previously such jobs would be
printed with a white border.
User Interface Improvements
◆
Changed “Image Settings” menu name to “Default
User Settings” for more consistent nomenclature.
◆
Informational pop-up boxes can now be dismissed by
pressing any valid key on the Control Panel.
Previously, the user was forced to wait for this type of
pop-up box to disappear before proceeding with
Control Panel operations.
◆
When a Control Panel data-entry operation is
cancelled by pressing the MENU key followed by the
CANCEL key, the cancelled operation is now
confirmed by a pop-up box. (Obscure)
◆
“Please wait” pop-up box now displays on Control
Panel when requesting a print head calibration
during a print. (Obscure)
◆
Pop-up box confirms now reset operations on Control
Panel (for example, resetting the default media).
◆
Smart card removal now causes Control Panel beep
regardless of fault tone or volume settings.
◆
MENU key is now available from help screens.
◆
Corrected problem where Control Panel keys would
beep even through key-beep had been turned off.
◆
Imager no longer reboots unnecessarily when
network addresses menu is entered but no changes
made.
◆
Help text added to MCM menu.
◆
Corrected problem where key-beeps were disabled
after entering a feature key. (Obscure)
◆
Improved key-repeat operation when holding down
Control Panel keys. It is now easier to use.
◆
Other miscellaneous user interface clean up.

◆
Improved DirectVista ® Film density accuracy.
Sensitometry tables have been improved to allow more
accurate mapping of image data to printed output
densities. This also eliminates “contouring” effects on
certain test patterns such as smooth gray wedges.
◆
Eliminated incorrect displayed values for densitometer
calibration defaults. The displayed values for the default
densitometer calibration were previously confusing
because they did not accurately represent the internal
values. The default values are now always displayed as
“0.00.”
◆
Improved Multi-Modality test print. The “MultiModality” test print has been updated with more
modern medical images.
◆
Color test image improved.
◆
Cassette barcode reading reliability improved. Software
for reading and decoding the cassette barcode has been
made more reliable resulting in fewer failed reads.
◆
Ribbon patch detection improved. The software for
detecting each color patch on a ChromaVista ribbon has
been made more robust. This improvement helps to
prevent skipping of patches resulting in incorrect colors,
especially with A4 paper.
◆
◆
◆
◆
End-of-ribbon handling improved. Previously if the end
of the ChromaVista ribbon was reached, and the user
opened the top cover, and then closed it without
replacing the ribbon, the imager would try to printing
using the spent ribbon. (Obscure)
Improved centering of printable area on A4
ChromaVista and DirectVista Paper. Previously, images
printed on A4 paper were shifted approximately 0.100”
to the right.
Job Settings file names properly truncated. Remotely
sent Job Settings file names > 16 characters are now
properly truncated to 16 characters. Previously, this
would cause a software error requiring the system to be
rebooted. Currently, Job Settings file names > 64
characters still cause the imager to lock up requiring a
reboot. (Obscure)
Miscellaneous reliability improvements. A variety of
additional minor changes were made to the imager
software to improve overall operation and reliability.
Known Issues
◆
◆
PostScript Interface Issues.
◆
Windows Network Protocol (SMB) not yet supported
for PostScript printing from Windows NT, 2000, or
XP. Workaround is to print via LPR interface.
◆
Imagable area used by PostScript RIP does not
always match imagable area on printed sheet. In
certain cases, this prevents the entire printable area
from being utilized.
◆
There is currently no driver uninstaller for Windows
NT 4.0 or XP.
DICOM Interface Issues.
◆
DICOM hosts that leave associations open will cause
the Horizon Activity light to flash even though there
are no jobs queued.
◆
Unsupported DICOM image compression results in
an “out of memory” error at the host.
◆
DICOM file format not yet implemented for nonDICOM interfaces such as LPR and FTP.
◆
Using a Magnification Type of NONE with the
'specialBracket' device causes blank cells with the
caption “Image Processing Failed” to be printed
instead of the image. Work around is to set the
DICOM Magnification Type to something other than
NONE.
◆
FTP server does not support passive mode connections.
Workaround is to disable passive mode in FTP client.
◆
Gamma/Contrast bracket prints say “TCR” instead of
“Saturation.”
◆
Unnecessary ribbon consumption. Some systems will
occasionally advance the ribbon too far causing
unnecessary ribbon consumption.
◆
Automatic color print detection currently checks only
the first image on a sheet.
◆
An empty VMF canvas (a sheet with no cells) will
result in an error and cause the imager to reboot. Only
special custom applications use VMF (Variable MultiFormatting). Neither DICOM nor PostScript use VMF.
◆
SA-1000 not fully supported. Extraneous error messages
on SA-1000 Network Framegrabber related to Horizon
imager status.
◆
Captions not supported with landscape printing.
◆
Color saturation adjustment not yet supported.
◆
Installed captions appear on color test print.
Workaround is to turn captions off in the Default User
Settings menu.
◆
ChromaVista print jam clearing problems. A
ChromaVista print which has jammed while rewinding
the sheet for the next color-pass reports a second jam
after the first one has occurred. Also, such a jammed
print cannot be purged. If such a jam occurs, the work
around to purge the print is as follows:

1.
After the jam has occurred the top cover will be
opened and the Control Panel will display the
following error message: “Clear media jam from the
printing area.”
2.
Remove the receive trays and clear the partially
printed sheet.
3.
4.
5.
Insert the receive trays.
Close the top cover.
The imager will now attempt to automatically
resume printing. (a pop-up box will read “Printing
resumed.”) Press the PAUSE key immediately after
this happens.
Remove the ChromaVista paper cassette.
Purge All Print Jobs from the Control Panel “Utilities”
menu. Note, this purges all queued jobs.
Replace the ChromaVista paper cassette.
6.
7.
8.
◆
Dmin and Dmax incorrectly applied to ChromaVista
and DirectVista Paper. This applies to Job Settings or
remotely configured User Settings (does not apply to
Default User Settings configured from the Control Panel).
Workaround is to set Dmin to 0 and Dmax to 300 for all
paper prints.
◆
Software cannot be downgraded from 1.6.0 to an earlier
version. For 1.5.0 or 1.5.2, work around is to use the 1.5.0
KDU Firmware Downgrade Disk (part number SP00147). There is no work around for versions earlier than
1.5.0.
◆
Automatic file system cleanup is not performed when
captions are installed. For optimal performance, work
around is to uninstall captions, reboot imager, and
reinstall captions approximately once per month.
◆
A4 paper size unavailable in Windows 2000 PostScript
driver. Work around is to select “Letter” for the paper
size and “Scaled” for the sheet layout.
◆
Macintosh formatted Job Settings Files to not work
correctly. Workaround is to save Job Settings Files in MSDOS or Unix format before sending them to Horizon.
◆
System Job Settings file “1417-dvf” does not work.
Using a system Job Settings file name (or DICOM AE
title) of “1417-dvf” does not direct jobs to 14x17
DirectVista blue film as indicated in the User’s Manual.
Workaround is to use “1417-dvfb”.
