Definition:
When the Ink level in the ink tank drops below the low level rod (500ml) this "Ink Reservoir Low Add Ink"
warning will be displayed as shown below.
Corrective Action:
Add Ink (see Section 3 Sub-section "Add Ink and Make-up")
Ink Probe Shorted
Definition:
This error will occur when the CPU board senses a short on any of the Ink level sensing circuit.
Corrective Action:
1. Remove the Ink Manifold from the Ink tank and ensure the level rods are not touching each other.
2. Remove the Level Rod Wires from the rod on top of the Ink Manifold. Then unplug the level rod
cable from the CPU board J12connector. Ohm each wire for continuity. If a short in found replace
the cable assembly.
3. Replace the CPU board. (see the CPU Replacement procedure earlier in this manual)
Makeup Reservoir Full
Definition:
The Make-up Tank level is monitored continuously with 3 level rods to maintain the optimum level of
Make-up. When the level gets to the "High" level sensing rod, there will be ~2200ml of Make-up in the
tank. This will send the "Make-up Reservoir Full" error/fault and will shut the printer down. This is to
prevent Make-up from spilling out causing a hazardous condition. The normal operating level is between
1500 to 374ml. See Fig 1 below.
