Same Problem
Had a same problem on my JV3 on black channel. tested the board, one of the transistors (C4131) was blown. Can that also cause the same issue?
Same Problem
I had a same problem on my JV3. To check futher, i measured the transistors on the main board and noticed a C4131 transistor was toasted. Can that be the cause for a similar problem on print?
Need some advice urgently.
I am busy converting a VS640 from CMYKlclmWhMet to a CCMMYYKK. Problem is on service mode, in the ink type section, I don’t have an option for MAX 4, only have PIG 4 and CMYKlclmWtMet.
Please advice.
My email address is world.focus@mweb.co.za.
Or if i can...
I am also planning to change my VS640 to dual CMYK. And I guess it is pretty straight forward. My email address is world.focus@mweb.co.za
Please email me a copy of the service manual
much appreciated
