There is a way to prime cartridges that have a sponge on the bottom of them. I need to make a video to show our customers how to do this. But here are the basic procedures:
Tools needed: Syringe (provided) and a good amount of napkins.
1. Take the cartridges out and flip them upside down so the sponges are facing the ceiling.
2. Prop them up on your desk so you can use both of your hands.
3. Remove the air filters for each color from the ink tank reservoirs.
Now comes the tricky part where you have to 'flood' your cartridges to get rid of air within the system.
4. Put the syringe into the small hole (where the air filter was at) of the color you want to prime.
5. SLOWLY...and I repeat...SLOWLY push air through the system with the syringe. Some ink will come out of the cartridge where the sponge is at, which you will have to soak up with the napkin.
6. Once the color is 'primed', then quickly put the PLUG (not the air filter) back where the air vent hole is located.
7. Repeat this procedure for the other colors.
As far as the grinding goes, you might have to look into that and ask yourself some questions (1) Did the tubing get caught before, which might have messed the printer up? (2) Is there something caught on the track within the printer that is causing the grinding noise? or (3) Is my printer a 'lemon'?
