The main point is that it didn't have any ink firing through the nozzles for all that time. To keep a head working it needs to be running so it always has fresh ink going through it, and it isn't just sitting in there. This is what clogs and kills them. Soaking can sometimes recover heads that...

Yes, you cant soak them for months. as the solvent inside the head will evaporate and clog the heads with the left over pigment

If your heads havent been used since november chances are they are clogged now and will need replacing

Definite electrical problem. The head is getting the signal to turn on, but not getting an off signal, so it shoots ink continuously. Normally this is down to a bad head cable, so that would be the first ( cheap ) thing to change. If that doesn't fix it the next thing to check is the...

My favourites are the ones who order a custom made item, with unusual specifics, get it and then say 'oh it's not how I expected ( despite being exactly what the ordered ) can I return it?' Yes of course, I will put it on the shelf as I'm sure someone else will want a bright pink sign with...

Although with Digiprint, don't assume they are selling you a genuine OEM part.... Looking on the site one is a lot cheaper than the other and says the manufacturer is 'digibase'. Digibase is just the cheap chinese copies they order in. You can order proper OEM ones from Roland ...

The correct number is 6000004658

Same bottle and weight and label means nothing. The Chinese are so good at making fakes now to the eye they often look the same as the original. Look at a lot of the fake designer stuff they make now. Only experts can tell if they are real or not, and even then they often can't say for definite...

No, but you recommended people do without actually knowing if the inks are any good long term...

Nothing wrong with pointing members towards genuine savings on genuine products, but not suggesting members ( who may be new, and not know any better ) but dubious goods from China that may damage their expensive equipment!

Stick it down with superglue ? OK, they will never be able to get them off again, but that's their worry in the future :D

Really to be able to make a success of signmaking now you need to have a good understanding of vector based graphic design. Without this you won't get very far. However, often the best way is to jump in and start doing things and learn as you go along. Get a copy of Corel Draw, is MUCH easier to...

And ali express is notorious for selling fake goods

It was sarcasm. I don't particularly promote OEM ink, I use Jetbest myself and have for years. I meant using real Jetbest bought from one of their distributors, rather than bought from a dubious chinese site notorious for selling fake goods

They aren't hex screws, they are cross head screws but the one has been mangled

Pair of new DX4 heads : $1000 plus hoses, dampers, ink pump, wipers etc... $1500 ish. If you can't fit them yourself add an extra $1000 at least to this, plus business lost while your machine is down.... Definitely worth saving $30 on an ink cartridge from an unknown source rather than paying a...

Jewellers extractors will be way too small, they are designed for removing tiny screws in watches and that sort of thing. To be honest, and having had experience with having to remove head screws that have been stripped in the past, your easiest option is just to drill the head off. It will only...

Well with your turnover that should last you a good while then :)

It will probably be fine though. Probably. And you can be happy with the few dollars you have saved :)

Taiwan is not China. And its not hard to copy a label ( Jetbest probably buy the bottles from China anyway )
