Your technician needs to do a calibration of the cutting system. This includes tool height and tool pressure and requires feeler gauges and 2 different dial pressure gauges to be done correctly. In each setting (30 & 200), there is an adjustment to accurately set the pressure. If the pressures...

Glad to help and that your printer is running again. Please post a pic of the issue so I can verify if it is a ribbon issue. If it is a ribbon, it may possibly blow a fuse again, and possibly take out a transistor this time. It's not a bad idea to replace them anyway, but let's still see a pic...

That should be all we need.

Sure, I can help you. You will need a crossover network cable. Let me know when you expect to receive the board, as I will be out of town next week.

Darn it! Did you ever do a choke clean after changing the head and dampers? If not, try that. If that doesn't work, then it might be the head, just very odd to have the same issue with 2 different heads. Let me know the results of the choke clean please...

Did you give up on your printer or did you get it fixed?

Close the choke valve and swap the 2 cyan lines at the top of the dampers, positions C & F. Be sure to use a rag or something to catch any ink dripping while you are doing this. Open the choke valve, then do a power clean, a nozzle check and let me know the results. Please post a pic of this...

Unfortunately, it's kind of looking that way. If you did crisscross the ribbons on the K/C head itself, then you most likely blew the head temp sensing circuit, in addition to who knows what. As an example, the schematics show contact 13 on the connector one side of the head being the head temp...

The picture told me what I needed to know. You are running CMYKx2. The VS-640i has 5 possible ink configurations. It appears you may have a clogged ink supply line. Please send me a pic of the ink lines at the top of the print head showing the ink lines connecting to the dampers. A soon as I...

I have an idea, but I need to know your ink configuration first.

The fuses and output transistors can be checked with a multimeter. However, blown fuses and shorted transistors don't typically give you this error. If the ribbons were crisscrossed on the same head, it likely damaged other circuitry on the mainboard, which would be difficult to diagnose and...

As hand851 asked, let's start with a nozzle check. Having the exact same issue with a new head means the head isn't the problem. You appear to have changed just about everything that could be an issue. Is the captop a Roland OEM or aftermarket. If aftermarket, then I would suggest replacing it...

How did you switch the cables? Did you switch them like the attached diagram or did you switch the cables on the one head, i.e., move the left cable to the right side of the head and vice versa? The attached diagram is the only acceptable way to switch cables. You don't want to swap cables on...

I would suggest you call Bob @ Grafx Network - 888-335-5914. They are a tech company based in Atlanta and should be able to help you. Replacing the dampers 4 times in less than 2 months???

FYI, you will need a multimeter. If you don't have one, you can pick one up at Home Depot for a few bucks. If you haven't used one before, no worries, I walk you through it.

Anytime after 10am Eastern time...

Very tiring on the eyes, having also been there, done that. Worst was a massive USB chip on a Seiko 64 mainboard.

Please call me to discuss how to best troubleshoot this issue.

Got to be cooler up there then here in S Florida. High 90's today!

Excellent to hear! Where are you located?
