Epson SureColor F7170 User Manual page 107

Important:
When the remaining ink is 70 mm (2.8 inches) or more from the bottom of the ink tank and
a message appears stating, Refill Ink Tank, it is time to replace the ink tank. We
recommend replacing the ink tank at this time. Replacements and repairs will be provided
for a fee.
During replacements and repairs, the ink in the ink tank is discarded. This is necessary
because fine dirt, dust, and other foreign bodies in the ink cause the ink tank to
malfunction.
The ink tank replacement interval depends on the usage environment and conditions.
2. Lift the lock lever for the slider of the chip unit you intend to replace.
3. Insert a finger into the groove on the top of the slider and pull straight outward.
Important:
Do not tilt the slider. If the chip unit is dropped it may break.
