Yeah, you are right. The only thing is I don't look after main fuse, but printhead fuses :) Thank you anyway :thumb:

As I told you, the printer goes online, do all the test's and scale the role... Also the printer cut on test, and move the heads on print test... But NO INK. Printheads new, dampers are new, pump new also. I see the ink flow trough tubes when the printer do the cleaning. I changed the...

again... Hello, I just changed the transistors (only a pair was burned), I soldered new ones. Also I changed the resistors.. BUT STILL NOTHING :(( :frustrated: Now it seem that everithing is ok, but still not working... I asked arround and I receive the same answer: "check the fuses". Where...

The head board doesn't have any fuses or resistors on it, only a IC and 1 electrolitic capacitor. From the main board, I already measured 2 transistors (drivers) and 2 resistors... The drivers are shorted and one resistor is burned, one is only overheated.

I put the foto on the first page in this pdf file. jpg file limit of 1Mo is not enough so... please see the pdf. Thank you

I have a Mutoh and I had the same problem. A friend told me that the screws are weak and the printhead movement produce balance. Try to see if the screws are tight and/or the bottom wheels are blocked.

Still I don't see any fuses, only those resistors...

I looked well on it... It seems like a brown glue... Anyhow, the electrolitic capacitor doesn't leak this way, and if something was leaking nearby, the result wasn't in upside, but downside...

some kind of news... Hy ppl, flash news... I took out the board from the printer and I extract the resitors and the transistors. 4,7ohm resistor is fried, 2ohm rsistor is not, but looks bad. both transistors (PNP and NPN) have short-circuit between E and C, so they are gone. I ordered some...

Hello ppl, I put into a pdf some photo's of the main board. It seems like the 142 and 144 resistor are burned. Someone can tell me if there are the only ones? Or is possible to be also other components burned? Thank you, A.

Hello, I use also a sonic device to unclogg the printheads. One head from 5 or 6 gets damaged. I experienced two major damages: 1. The electrovalves gets stucked on off position 2. Electrovalves gets stucked on ON position And also for printheads with multiple chamber (like DX2) I noticed that...

Thank you all!!! The only problem can be that I am on a different continet :)) And I really don't know if ALL the mailing companies knows the word FRAGILE :/ I will preserve the offer like a plan B. Maybe is possinle to take a foto to my main board and to send it to you and you can show me...

Does anybody knows where are printhead fuses for Roland SC500? Thanks

Dear Mr.Salumi, Thank you for your response! Btw. "Che fatch?" in Romanian is "Ce faci?" :)) Anyway you are good! I attached head carriage board, can you show me where are those fuses? I cannot identify well enough :(( Thank you very much! Andrei

I have the same problem with my SC500... I changed every spare part... but no ink drop :banghead:

I just bought a second hand SC500 from a distant warehouse. After I put the printer into my shop, I changed right away both printheads with new ones (DX2). The sad thing is it's not firing ink :frustrated: !!! The cleaning is ok, the ink flows good, also the cutter works perfectly, the only...
