Even though it appears to be a software problem, I would check and clean your encode strip as well. We were having the same problem a couple months ago with PosterPrint 12, a JV3-250SP and very large EPS files with loads of empty white space. It turned out to be an issue with PP getting...

Thanks much, Flame! Just the kind of info I need. The search continues... Anyone know where I can get JV3 tall dampers for a reasonable price?

I found a website with really inexpensive dampers and wanted to know how they compare. They look slightly different (larger screen filter) and wanted to know what the benefit/difference would really be. Has anyone here used lavainks.com tall dampers with a JV3 and water based inks (we use...

Thanks for the info on the placement and purpose of the plate - that was something I was about to ask. I'm looking into local techs, but the boss has recuiled in horror at the request. The last tech that came out a year ago was from Vegas and I've had little luck in finding a local guy...

I found the little metal plates. They are Mimaki part # M508337. The Color Zoo out of Vegas has them for $10 each. Ouch. I have some nickle sheet kicking around - maybe I could make one as a placeholder.

Thanks everyone for the advice and assistence. We have had nothing but problems with this machine over the last month. The hight of both the capping station and print head caddy has been adjusted and leveled. The individual heads have been pulled out, adjusted and reseated. In every single...

Some people might not think twice about replacing parts on an electronic device while it is hot. I won't. I've seen too many machines die spectacularly that way. No, I always power down the machine as soon as I need to touch anything electronic. Oh, and the slider board was replaced a...

It really does feel like this machine has parts failing left & right...

Thanks for the cable ID's. We keep our gear *clean*. We run water based dye-sub inks for transfer onto fabric. The stuff cleans up nearly perfectly with isopropyl. I swabbed the bay out before dropping the new head into place. I have confirmed that there is a capping problem. I do get air...

Hi, In my ongoing effort to let our JV3-250SP drive me insane, we are having yet even more issues. At first it was just the yellow head, giving off a bit of a yellow halo around everything with Y in the CMYK mix. Then the behavior spread to other heads, most notably Cyan at the moment...

Yup, we entered the head id numbers. We also had to do it when we swapped the old board back in. Thanks for everyone's assistance. As mentioned, we swapped the old main board back in, and redid all our alignment settings from scratch.

Checked the cables - all of them... They were fine. We swapped the OLD mainboard back in ... and the OLD board works exactly how it did. I'm now seeking info on how to extract the csv file (or whatever it is called) from the OLD board so I can use it with the NEW board. The goal: see if it...

I was just thinking I should have a close look at that one, being as the space where the main board goes is so cramped. We had a really hard time just seing it as a support post is in the way! This morning is all about looking at all the connections, one cable at a time. And yes, it did let...

OK, here's an update: 1) New bulk ink cartridges with cheater chips - installed... 2) New Motherboard - installed... 3) Started inputing settings... 4) tried to do a test drop... Uh, oh..... After installing the new main board, this JV3 won't even produce a test draw. As in, it's like...

Monday is the day we start swapping this thing's guts out. We have new bulk cartridges with specialized chips in them. They were purchased at the same time, from the same place, as the new main board. I'm also planning on re-plumbing our existing bulk ink system to the backs of the new ink...

We've had some issues with this thing for a little bit. It prints "OK" most of the time, but it's been suggested we replace the main board for a couple of very specific reasons. I won't waste time as to why, as that is not the aim of this post. I've replaced print heads and a slider board -...

I want to thank everyone here so very much for the assistance in disgnosing and helping to resolve this issue. You have all been an increadible help! It turns out it was Linear Encoder Strip. There ware two, very very tiny dots of libricant that had dripped/splattered onto that strip from...

Thanks for the hay's people! Good to see you. Nice to see a couple people local to Seattle on here. For those looking for large format dye-sub on fabric in the Seattle area, we do a *LOT* of output. As well as sewing for even larger panels/banners/exhibits. However, we need some help...

Hi, We have a JV3 250SP that has been acting up lately. The heads and pump are fine, with no perceptible drop-out noticeable. In short, print quality is good, with a couple very specific exceptions. First issue: Over-all print alignment/registration settings will, on occasion, go completely...

Hey everybody! This is Dan at Warp Exhibits in Seattle. We run two Mimaki JV4 (160 & 180), a JV3 250SP with water-based j-eco inks on paper for heat transfer dye-sub. We also run an Infinito Fina 320 - with solvent ink for heat transfer dye-sub. I have more than 10 year experience working...
