A. Printer Installation
1. Verify all boxes have been received.
Box 1 contains the printer head and customer documentation (includes the System
CDs, Quick Start Guide, screws, and screwdriver). Also enclosed are 12
reservoirs, 12 cartridge tubing needles/septum
connectors.
Box 2 contains the stand legs, stand feet,
takeup and feed system media rollers, media
core, 2 media adapters, dryer, 2 dryer brackets,
dryer logic cable and Ink Prime box.
Box 3 is the accessory box which contains the ink
and cartridges, sample roll of media, cutters,
and all versions of power cords).
NOTE: You will need to provide an RJ45 Ethernet cable to connect to the Ethernet
port.
2. Remove all contents from Box 2 (2nd largest box).
Box 2 contains the stand legs, stand feet, take-up and feed system, media rollers,
media core, 2 media adapters, dryer, dryer brackets and all screws, dryer logic
cord, and Easy Prime box.

3. Flip Box 1 (largest box) upside down and open.
Remove packaging materials, 12 ink reservoirs, 12 cartridge tubing
needles/septum connectors, network parallel cable, and documentation.
4. Attach legs and feet to printer.
Caution: Do not damage leg harness wiring! Ensure cable is not pinched/twisted.
5. Rotate printer to one side and lift out of box using a two person lift.
Ensure all plug connections are intact.

6. Attach dryer brackets and install dryer plenum.
Note: align the dryer plenum guide pins with the dryer brackets.
7. Secure dryer logic cable and power cord. NOTE: If installing the new
universal dryer (black metal) ensure the underside voltage selector switch
is set to either 115VAC or 230VAC depending on region.
8. Activate diagnostics ‘legs test’.
Ensure media rollers and dryer function normally. Both rollers should initially pulse in
one direction. By blocking either the top sensor or bottom sensor path the opposite
roller should reverse direction. Dryer should intermittent pulse every few seconds,
after 5 minutes the air leaving the dryer should be warm.

10. Load media into printer. Ensure alignment guides are set properly.
Note: maximum weight of media roll is 60 pounds.
Verify media loads correctly and is measured properly.
Check UTILITY MENU – DISPLAY SETTINGS for proper media measurements.

B. Ink Installation
1. ‘Plug and Play Cartridge’ characteristics
2. Installing ink into reservoirs
It is suggested to fill reservoirs over a table to prevent spills on printer; fill to a
maximum of 400 ml (50 ml minimum).
3. Attach septum fitting to valve body. Prime line (and cartridge if
necessary).
NOTE: When the valve body is raised to the up
position ink flow is cut off, when the valve body (latch)
is closed then the ink line is open.

a) Prime line using the short needles
(purple in color); attach short needle
to each of the 4 valves. Connect
septum needle to EasyPrime by
inserting into female receiver.
Depress and hold EasyPrime
activation button to provide a solid
burst, wait 20 seconds, or until ink
line is full.
b) Lift valve actuator (to up postion)
and remove purple septum needle
assembly.
c) Connect cartridge’s septum needle to valve and close valve – wait 60 seconds,
then remove the blue tape from cartridge jet plate!!
NOTE: If attempting to recharge an
existing cartridge, then disconnect
cartridge from stall position and
prime cartridge (print head) using
multiple sets of one-second bursts
until ink is visible in the ink line.
This may take 1-2 minutes to
accomplish depending on the
prime of entire ink line. Ensure
EasyPrime adapter is flush to
cartridge jet plate – a siphoning
sound (slight sucking) should be
heard when priming the cartridge
properly.
4. Activate the color test pattern for ink starvation problems.
Select: SETUP MENU – PRINT MODE MENU – PRINT PASSES – SELECT 3, OK.
Select: UTILITY MENU – SERVICE MENU – DIAGNOSTICS – COLOR TEST MENU –
STALL SELECT (or ALL COLORS)– choose color. Select DENSITY SELECT to 100%.
Select COLOR TEST PRINT. Verify color bar is printed without ink starvation.
Ink Test/Recovery Procedure
(Color Test Print)
This is a pressure test of the
system, so please disregard the
two-pass quality. Each pass of
the carriage assembly should lay
down a solid band of color with
33% ink load.

Color Test Failures:
- Example A above depicts
complete ink starvation in magenta.
This problem may be corrected by
using the EasyPrime and
establishing the required pressure
inside the cartridge. Replace
septum connector/needle if repeated
attempts continue to fail.
- Example B above depicts partial
ink starvation in magenta (ink fires
at 100% at the beginning of each
pass but then starves). This
problem can be corrected by
ensuring 19 ml of ink is present
inside the cartridge (level must be between 8 ml and 35 ml for proper operation – refer to
NOTE below).
NOTE: If you are installing a new Warranty print head (empty), need to revive a
deprimed cartridge due to ink starvation problems (see H-11 on page 30 for example) or
to verify proper cartridge ink levels, obtain syringe with extension tube from accessory kit.
Pull 20 ml of ink into syringe from ink reservoir or new ink bottle. Lift cartridge stall
position valve to up position to cut off ink flow (NJ700-800 series only). Temporarily
remove septum connector from cartridge. Install ink into cartridge by depressing syringe
plunger; pull back on plunger to remove excess ink (if any). Reconnect septum needle to
cartridge and close valve actuator (lower) to restore ink flow to cartridge. The cartridge
will need to be primed to restore negative pressure inside cartridge – refer to step 3
above.

5. Activate the Prime pattern.
Select UTILITY MENU – PRIME.Verify all colors are printed. Verify no clogs are
present in the prime pattern. Manual or automatic jet compensation is provided up to 20
jets in each cartridge. Ensure the integrity of the diagonal lines are consistent and
smooth. Clean or replace cartridge if unsatisfactory.
6. Manually Bypassing Cartridge Jets
A manually bypassed jet appears as an 80% filled block
in the prime pattern (see jets at left and right below).
Perform manual jet bypass whenever a jet illustrates
degraded performance (i.e. clogging or fire misdirection).
In the example at right the magenta cartridge is severely
misfiring – the cartridge will most likely need to be
replaced.

Blown Jets
To manually bypass a clogged black (i.e. K) jet, perform the following steps:
In the example below the Magenta jets are illustrated completely blown (100%
filled blocks), but are being automatically bypassed by the printer. There is no
need to manually bypass any of the jets seen here. As long as the printer still
supports a desired print pass mode (refer to top of Prime pattern) then printing
may continue as normal. If the cartridge is still under warranty (<500 ml) and
more than 10 jets are blow, as observed in the Prime pattern, then this qualifies
as a cartridge replacement.
