The pressure sensor gives a negative value. If the pressure is negative, there may be an error

in the ink pressure PCA or in the ink pressure sensor cable. Check both by looking at the

connection of the cable to the ISS PCA and at the pressure sensor PCA. Press OK to cancel

the purge process.

2. If the pressure is positive, probably there is an air bubble inside the cartridge connector tube

column. Prepare the syringe again, then press OK.

3. Insert the same syringe into the ink cartridge and fill it with 20 cc of ink for the color selected.

4. Check that there is no air in the syringe by hitting it a few times. If there is air, hold the syringe

vertically with the needle up, so that the bubble of air rises to the top. Put a cloth around the needle,

and press gently on the piston to remove the air from the syringe.
