Black ink problem!

[stoogenc]

I resently changed out my printheads on my falcon jr. Now i'm not getting any black ink. I replaced the heads,changed the rank, suck the black line to the damper and suck the ink thru the damper. I did a power clean and still no ink. Do you have any ideas? My work load is backing up on that machine HELP!

Did you try pulling from the waste line while holding the carriage in the "Home" position on the capping station?

 

[stoogenc]

I just tried that and still no ink being printed.

no ink as in zero? when you do a cleaning cycle, is there new latent black ink in the capping station?

 

[stoogenc]

Yes, NO ink. I've done a power clean and you can see it in the waste tube. When I did the suction on the capping station you can see wet ink. This is driving me to drinking more.

head fuse?

Where would I find that fuse and is that a problem that can be fix here at the shop?

Depends on your skill level at soldering surface mount components on pcb's.

Well, that looks like we can do that here. I see the fuses on the motherboard. Now, Where do you think we can these? I going to do a test on the old now.

Thanks

What would be the best way to test the fuse? So, I have an idea before I let this person do a test. Just being safe.

the best way to diagnose/isolate a data issue is with a data swap (sapping ribbon positions). i know how to do it on my printer. but each printer is specific. maybe someone can lead you through it for your model. if you do it wrong you can damage parts.

essentially it will tell you if that side of your head is dead, or it's just not getting data.

My concern is if you dont know how to test a fuse, you probably should not be attempting to remove and replace it. You can easily damage the main board.

Make sure the machine is powered off and unplugged, hit the power button a couple of times.

No, but I have a real good employee said he could change it. I just want to be sure and know what to expect. I'm not about to invest in motherboard that's why I asked. Do you know where we can get fuses if needed.

I have a post there with a fuse holder and part# for the fuses and source.

Bayshorecreations has a photo walk through as well.

Thank You All for your help!

Good luck, but be careful!

We tested the fuses this morning and the fuse on the left facing the motherboard fuse F2 is bad, is that the black head fuse? Is there a place to buy the original fuse for replacement?

 

[randya]

No, I dont think so, we get ours from:
