Need Help PRINTHEAD NOT PRINTING CYAN OR MAGENTA! - FUSE KEEPS BLOWING? XC-540

[Adam24]

Hi Guys really need some help on my Roland XC-540 it has been offline for around 2 months now.
The CYAN & Magenta is not firing at all I changed the fuse and it has blown almost instantly when I put it in and turned it on. Luckily I have a spare fuse however thinking there is no point putting the new one in without finding out why it has blown again.

Do I need to change the transistors too? I changed the cables and fuse but not the transistor. The Yellow and Black print head is perfect and working as normal just the Magenta and cyan.

Here is a link to my original post but had no luck with solving this.

try replacing the fuse and turning on the printer with the disconnected cables to the printhead. If fuse will burn, then change transistor. If not, I get you manual for checking printhead with multimeter

Change head flex cables. It must be shorting & blowing fuse.

Guy last logged in six years ago, maybe they figured the problem out already.

Nah I reckon he is still sitting there waiting for a reply, and now thankfully he can get his printer running again

Well, here's hoping they kept the ink circulating the whole time to prevent it from clogging up. 40 or so liters of flush later...
