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.
