Perhaps your capping tops are dirty and clogging your heads when they rest on them. have you tried replacing the caps?

Hi all, I have an Epson 10600 and can't get the printer to recognize cartridges. I have another 10600 running and I swapped out the working cartridges and it still didn't read. I just sent the main board out to be repaired and now I have the cartridge recognition problem. I have a feeling it is...

Hi, I can not rid my JV4 of these faint blk lines. They print at intervals of about 10 inches and go all across the 64" paper. I have tried using only front heads and only back heads. Same issue. I have cleaned heads underneath with swab, ran strong clean but can not get rid of them. I included...

I recently had this problem on my JV4 and I was told to replace the heads one by one with a head that is electrically sound. On the first one I replaced (black) the other colors fired. I had a bad head!

Hi All, I have an issue with my 10600 printer. I can not get a computer to see it. I have 2 10600's and one is working fine so it's not the driver or the computer, I actually tested it on a another desktop and same issue. it seems the computer will not see this printer at all. I have tried the...

Sorry I was going to post pics. I still have the issue. I cleaned the slider board with alcohol and a Flux brush. Looks new now. Cleaned ends of cables. Cleaned encoder strip. Cleaned main board. I don't believe it's the slider since I replaced it with one from my other jv4 and still had...

Thanks guys!! Much appreciation! I will start by cleaning off the slider board and re-seating the cables. I did not do the data swap correctly. I did not swap in pairs. Will keep you posted once I have the board cleaned. Have a great weekend everyone!

Ok I have new info: if I reboot the machine it will fire all heads 1-2 tests then drop out. every time I reboot they will fire. Anyone ?

Ok did the data swap and got bad result perhaps i did it wrong. See attached. Any thoughts?

Thanks walker that helps me a lot. I never understood that part. I will try the data swap and let you know what I come up with.

Artbot, when you say data swap do you mean switching data cables on the slider board with the known good channels?

Thanks guys!! I have replaced dampers no change. I don't see how it could be the pump since I can draw ink out from tube underneath capping station then immediately run a test. No print. Since the head has ink in it from the syringe draw I wouldn't think it's the pump. During a print how does...

Hi All, If anyone knows JV4 I have a situation for ya: 4 heads not firing, only the LC and LM on front and back are working. If the printer sits a while (hour or so) they fire great on a test. Run another test right after and I lose them. Clean does nothing. I have changed damper and I can draw...

I never did the decoder to work. i moved on to an Epson 10600. I bought 2 used for great price. I have one set for sublimation and it has been working fine until recently. I had a blocked Blk/Cyn capping station . tried to fix but ended up replacing it with the one from the other machine. Fired...

Thanks everyone for responding. I believe it is a locked head as I have installed the r1900 head and the original 2 times each. the original head works fine and the r1900 head pulls a code each time. The problem with the original is that the head is clogged about 70%. I have two DX5 heads (now 3...

Hello All, I just pulled a DX5 head out of a r1900 and put it in my 7880. Getting an error code 0001001B. Is this a locked print head and will not work in my 7880? I checked everything else out including putting old head back in and it worked (except for the usual clog). My 4880 and 7880 heads...
