HELP! VP-540 Sparked, now no black or Cyan firing at all!

Post by itfben » Wed Dec 21, 2016 5:50 pm

The foam covered metal damper cover was being refitted and the printer started doing a test price before it was all the way in, there was a spark and suddenly the black and cyan heads completely stopped firing, nothing comes out of them now. the magenta is fine but yellow is only half firing. I assume I might be a fuse but think I ordered incorrect one (see order) need sorting straight away and need correct part as soon as possible. any ideas what part I need? or how to fix?

tried turning it off and on again

You may have shorted cables and/or damaged cirquit boards and should be diagnosed by a service engineer before doing anything else.

I replaced two fuses. All colours printing in test print. Albeit, the cyan seems to be 100% ok when going to print sonething so leaks a huge printhead suzed streak across the Media. Doesn't do it across media when the machine turns on but does when it test prints. Could this be due to my print head ribbon cables (35cm long x 21pin ones)??? I ask as the tips that go into the printhead end don't all look perfectly straight any more.

It's possibly a cable or board that has been shorted, I would suggest that an engineer visits to help determine the fault as changing individual items could potentially be very expensive.

what would cause half the magenta side of the cyan head to do this the black side of the cyan head is fine, i know this as i unplugged the data head cable on the magenta side and the streak was gone but obviously so what the right side of the cyan on the test print.

An engineers visit is going to be expensive. How many parts can you fit for 2hours of a labour for a roland engineer? Surely there can't be much left that can cause this? Even my engineer I use is scratching his head.
