Update, pulled the board out,changed the transistor and now everything seems good

They`re in Germany not UK, although they can deliver in a couple of days

I'm hopefully only looking at a couple more days out of work. It won't take long to change the transistor but will take a day or 2 to get it. As long as the transistor is the problem I will be good to go. I've searched everywhere for an alternative place to buy other than Roland but it's...

Unfortunately that would be very difficult to execute. I feel like i may be near the end IF this transistor is the problem,there is no doubt it is a problem,i just need to find one from somewhere other than Roland as their prices are daylight robbery.

that s what i did in a long winded way (E + B),they all test 42-43 apart from 1 (1746)

also would this 1 transistor knock out all my print?

Hey Joe would you be so kind as to check my reply out and let me know if i have managed to find a bad transistor? i dont know what i`m doing i`m just winging it :) thank you in advance

i feel like i`m just thinking aloud here tho someone might benefit in the future with similar issues. i`m 99.9% sure that 1 of these transistors are my problem...and i think it is the C4131s (number 3 outer in my DKWID diagrams) (Dont Know What Im Doing) As i dont know how to test them...

i`m also guessing i need to test these? and would anyone know the specs of them so i can find them here: https://uk.rs-online.com/web/c/?searchTerm=transistors

I`m still in a pickle. the print head cables aren`t due until tomorrow however a bunch of fuses turned up so i thought i would try new fuses and taking the print head cables out completley including out of the carraige board. I did this and the fuses blow straight away when the machine is...

Thanks for the reply,I'm on my mobile at the moment so it's difficult to read and reply properly. This has been absolutely flawless up until now,I've had one head change only because it jammed and dented the head but even then it only knocked the white out but I needed the white. A roland...

thanks for the replys bud i REALLY appreciate it :)

i have ordered these: https://uk.rs-online.com/web/p/non-resettable-fuses/7382902 however i `thought` i`d read somewhere the roland fuses were 72v but i dont know where i read that it is just dotted down on paper, does anyone know what the actual v should be? i dont want to cause more damage...

ive ordered new print head cables to eliminate that. wil lsee what happens

Further to this,received 2 fuses today which cost the best part of £50 delivered absolute rip off seeing as they are worth 70 pence, tested them and got a reading so fitted them, they blew instantly, 50 quid I am very quickly heading for going bust ,throwing money at this machine and not having...

yes i get a reading with the wires touched together,just not either end of the fuse. looks like this is the problem, i started the machine back up without the fuses in and it runs so process of elimination these must be (or almost must) for the print head. thanks for your help and hope this...

sorry took pic on wrong setting,it was 1 click over to the right. but no materr what i set it on the result is the same (1)

this multi meter does`nt beep, reading just stays on 1 it does`nt move. so both dead? i hope these are the fuses for the head,i dont know tho it was just a guess.

so i dont know what i`m doing with electrics but i took the back cover off and these look highly likely to me. i dont really know about testing either but i put the multi meter in diode mode and the reading stayed at 1 am i dong that right? should`nt it read higher than 1? (which is what it...

thanks for the reply. if someone knows more it would be a great help, what to chek re fuses and where they are,what they look like etc attached carraige board pics, it looks fine tho i guess you wouldnt know without testing if any of these components had blown? i`m not great with electronics...
