Empty Tubes

Symptoms:

• One or more of my tubes are totally empty in the morning or after a few days of no use.

Solution:
The PermaFlow is designed to have some air space on the top of the cartridge. This air space acts as a siphon break. If it were not present, there is a chance that ink could siphon directly from the bottles into the printer making a huge mess. If you see any small bubbles in the ink lines, these will be absorbed by the air space in the cartridge. It is not something to be concerned about.

The air space on the top of the cartridge will expand and contract with changing weather conditions. It is not unusual for the ink to retract as much as 6 inches (15cm) from the cartridge when the printer is not being used. This is just the effect of the air space on the top of the cartridge expanding. It does not mean there is something wrong. However, if the ink in the lines totally disappears and drains back to the bottle, this indicates that there could be a leak in the line. This is a serious problem and there may be a need to change the PermaFlow cartridge.
To test the integrity of the tube and cartridge, follow the procedure Air/Foam within Cartridge to see if you can bring ink down and make it stay in the tube.
