Question Roland SP540i wont print after changing the DX4 Print heads

fuses?

 

Did you remove the ac cord from the machine before removing anything?

 

First thing I would check is the fuses on the main board.

 

Yes fuses are the likely culprit. And/or cables. If you have bent or broken a ribbon cable termination (very easily done) then this will cause the fuse to blow. Hopefully it has not taken out the main board.

 

Definitely fuses. Unfortunately they are soldiered on the mainboard on the SP.

 

Hi Daniel,
I'm having the same issue. Did you have any luck fixing the problem? I replaced the manifold on my H1 Blk / Cyan and had it printing but after running cleaning fluid through the lines & refilling inks this is what I'm getting via test print... its doing weird stuff, first test image is yesterday and second is this morning...

 

Before jumping into fuses and electrical issues (The Rabbit hole) make sure you have ink through the print head. Replace the cap, put the heads in the home position and then pull ink with a syringe. Once you get a healthy amount of ink in the syringe, put the cap hose back on the pump and do a medium clean. Then test. Most in drop out , even after a head replace is because of ink flow and not an electrical issue. Usually.

 

You must pull ink through the head very slowly and gently.
