Opening the Top Cover
The latest versions of the imager do not automatically
open the top cover when using the Open Top Cover
menu option on the Main Menu at the front panel. It must
be opened manually.
However, before manually opening the top cover, you
should still select the Open Top Cover menu option to
ensure that the print head is retracted. Then press one of
the two green releases shown in the following figure to
open the top cover.
NOTE: The top cover is spring-loaded. Place your hand
lightly on the top cover before pressing one of the
releases to prevent it from opening too quickly.

Removing the Receive Tray
The latest versions of the imager include only one receive
tray. Media pulled from any of the supply slots will be
placed in this receive tray.
To remove the receive tray:
1. Open the top cover. Refer to “Opening the Top
Cover.”
2. Lift the front of the receive tray up.
3. Pull the receive tray out away from the imager.
Print Head Positions
The latest versions of the imager have two print head
positions:
•Shipping position, in which the print head is closer to
the back of the imager. This should be used prior to
shipping the imager to prevent damage to the print
head or platen bearings. It should also be used when
cleaning the print head or platen, as the position
provides more room between these components to
make cleaning easier.
•Printing position, in which the print head is
positioned closer to the platen, ready for printing.
Changing the Print Head Position
To change the print head position:
1. If imager power is on, select the Open Top Cover
menu option to ensure that the print head is retracted
and move on to the next step. If imager power is off,
move on to the next step.
2. Open the top cover by pressing one of two green
releases as shown under “Opening the Top Cover.”
3. Pull up on the two release handles, shown in the
following figure, and use the handles to push the
print head back to the shipping position or forward to
the printing position.
CAUTION: Position the print head with care.
Do not drop the print head into the printing
position. Doing so could cause damage.
4. Lower the release handles to lock the print head into
the new position.

Cleaning the Print Head
Before cleaning the print head, you must manually move
it to the shipping position. Refer to the procedure above
under “Changing the Print Head Position.”
Otherwise, you can follow the procedure as described in
“Cleaning the Print Head and Nosepiece” in the Horizon
Imager User’s Manual.
The alcohol concentration of the Print Head cleaning pad
is 99% isopropyl alcohol (IPA).
1. Locate the print bead and nose piece.
WARNING: The print head may be hot. Also,
when cleaning the print head, avoid the
extreme ends of the print head, which are
sharp.
2. Using a print head cleaning wipe, carefully wipe back
and forth along the entire length of the print bead line
with moderate pressure until the print bead is
completely clean. The cleaning wipe may become
discolored. Do not use the platen roller cleaning wipe
to clean the print head as it will cause damage.
CAUTION: Use only a print head cleaning
wipe when cleaning the print head. Also, do
not touch the glass surface of the print head
with your fingers; it could damage the print
head.
3. Clean any dust or other contaminants from the
nosepiece.
4. Wait for all cleaned components to dry thoroughly.
Cleaning the Platen
Before cleaning the platen, you must manually move the
print head to the shipping position. Refer to the procedure
above under “Changing the Print Head Position.”
Also, the latest versions of the imager do not support
jogging the platen from the front panel. When cleaning the
platen, you have to use your fingers to manually jog the
platen so that you can clean its entire surface. Make sure
that you clean the areas where you have touched the
platen to remove any oil from your fingers.
Otherwise, you can follow the procedure as described in
“Cleaning the Platen and Donor Guide Bar” in the Horizon
Imager User’s Manual.
The alcohol concentration of the Platen cleaning pad is
7 % IPA.
WARNING: Remove rings, ties, jewelry, and
other items, and tie back hair, so that they do
not fall into or get caught in the imager.
Nosepiece Print bead

1. Looking in from the side of the imager, locate the
white platen roller.
2. Using a platen roller cleaning wipe, rub the pad along
the entire length of the platen from end to end until
all visible contaminants are gone. Do not rub back
and forth.
3. Manually jog the platen with your fingers and repeat
step 2 until you have cleaned its entire surface.
4. Wait for all cleaned components to dry thoroughly.
Cleaning the Pick Tires
Before cleaning the pick tires, you must remove the
receive tray. Refer to the procedure above under
“Removing the Receive Tray.”
1. Remove any cassettes from the supply slots.
2. Locate the pick tires. There are three pickers for
Horizon GS, two pickers for Horizon G2 and one
picker for Horizon G1.
3. Using a platen roller cleaning wipe, wipe around each
tire. The cleaning wipe may become discolored. Be
sure to remove any loose or peeling debris that is
present on the tire. Firmly rub the tires with the
cleaning wipe until all loose debris is removed.
NOTE: Extremely dirty tire shown for illustration
purposes. Do not let tires get this dirty.
CAUTION: To avoid damaging the pick tires,
use only the platen roller cleaning wipe. Also,
do not touch the pick tires; body oils from
your fingers are hard to remove and could
eventually damage the tires.
4. Wait for the pick tires to dry thoroughly.
NOTE: DirectVista Blue-T film printing may require
more frequent pick tire cleaning.

General Cleaning
You should perform imager cleaning procedures as
recommended in the Horizon Imager User’s Manual. Clean
the cassette area, sheet exit area, basement and imager
cabinet with a platen roller wipe every 2 sheets or
more often in dirty conditions. This will eliminate dust
build up, remove any pick tire debris and prevent dirt
from getting inside the imager.
DirectVista Blue-T film sheets can sometimes stick
together in high relative humidity environments. The
steps the imager takes to pick a sheet of film are slightly
more aggressive than standard DirectVista Blue film. DV
Blue-T printing may require more frequent pick tire and
overall imager cleaning.
