[druckpreiswertcom]

I m new here.

My Mutoh Valuejet 1304 dosent print after trying to print a Logo on Banner.
No Nozzels more but ink flows thru the printhead by Cleaning.( P​rinthead does not fire Ink )

I´ve checked fuses on the Mainboard = all fuses are OK.
I´ve checked Transistors on the Mainborad = all OK.
I´ve checked maintenance Station = Ink flows thru the Printhead. ( OK )

Now I dont Know what to do.

please Help If You have experience with this Issue.

If it suddenly threw down those lines, look like the main board went away. The fuses could still be fine, but the circuits are dead.

First . thank You for Quick Answer.
Is nothing to do with Mainboard?

When I send a Job to the Machine.
The carriage ( printhead ) moves left and Right but the media keeps White.

judging by the fact that I assume the last thing through the heads is that black garbled mess, there are problems with your head cables.

Thank You J Hill Designs,

best Thing is i order today new Head Cable and change the Cable.

The F2 fuse on your motherboard has to be blown. I have never seen a printer do what you describe without a bad F2 Fuse.

Hello chrisphilipps,

where is located the F2 Fuse?

 

[chrisphilipps]

Yes that is the F2 Fuse.

i already replced the F2 Fuse on Mainboard.
Right now when I´m turing the Machine on , after 5 sec. goes the Machine Automaticly off.

Our Valuejet did exactly the same as yours about 2 years ago.
Changed F2 fuse replaced print head and printhead cable (use an original Mutoh cable) and has ran sweet ever since.
It is probably shutting down as it can sense their is something else wrong.

Remember fuses are there as a protection to a circuit, so the fault was not the fuse, the fuse is a fail safe for another fault.

You probably have something plugged in wrong. The F2 Fuse controls the print head circuit, if it was bad it wouldn't prevent the printer from turning on. I would also recheck the fuse and make sure that you didn't leave solder anywhere else on the board that might be causing a short. That F2 Fuse is very small on the original generation mother boards and it is not easy to replace.

Even if you get it replaced properly and powered back up you will most likely still be missing one of the 8 channel in the print head. I have found that when a short like this happens and the F2 blows the channel in the head that got the short also blows. You should replace the Head Cables and Print Head, possibly the CR cables as well depending on what they look like.

First. thank You all for Your Help.

I will wait for the new Head Cable , and I report what will happen when I replace the new Cable.

Thank You again to All.

Obviously, check all the fuses (7 of them on main board)

When we have a problem, we send board out for repair to inkjetperformance.com

Flat rate circuit board repair. I just sent out a main board for mutoh.

$450, i believe
