Definition:
The ci5000 series printers constantly monitor fluid levels in the Ink & Make-up tanks. These levels are
maintained to a volume that allows fast and easy viscosity control during normal operation. This is done
using 3 level rods (low, high, and a ground) that are underneath the Ink Manifold. The ink is detected
between the ground and high or low level rod. When the level in the ink tank drops below the low level
rod an "Ink Reservoir Low Add Ink" warning will be displayed. If after 8 running hours the level has not
risen above this Low Level rod, the printer will shut the printer down to ensure the ink level does not drop
below the Ink Pickup tube. If this happens, damage can happen to the Ink Pump.
Corrective Action:
1. Add Ink (see Section 3 Sub-section "Add Ink and Make-up")
2. If not low
a. Check that the level rod wires are connected to the proper level rods. (See the picture
below Pic 1)
b. Ensure the power is off, disconnect the Ink Level rod wires from the CPU board (J12) and
using a multimeter check continuity of all 3 of the Ink level rod wires from the Manifold
connector to the CPU board connector for an open or break in the wire. (See Picture
below Pic 2)
c. Replace the Level Rod Wires harness (see page
replacement procedure)
d. Replace the CPU Board (see page
