    Have you done a wet soak? Putting cleaning solution in a pan and lowering the heads into the pan so that gravity pulls the ink down and away?

    all head cleaning solutions need to dry very slowly. I've used NMP straight, not mixing. It does not dry fast. But any left over ink will gunk up. It's best to flush which pushes the ink outward. If you ink is compatible with Acetone/BC then yes. That would be good to do a final clean.

    You'd have to do an acetone ink test by placing acetone on a cured print from your machine AND doing a blend test wherein you mix acetone with uncured ink and let it set overnight to observer its behavior. The blend passes if the ink shows no sign of sediment or coagulation.

    The NMP may have softened latent semi-dried ink into a skin? I've put several gallons of NMP through Toshiba CA4s. My usual method was to pull the top ink inlet and syringe the ink through the head. Have you done this?

    "Powering down" upon sensing media.

    I believe it was sitting in a warehouse for about a year, full of ink. The lines took forever to flush out. It's a VJ-1617H likely the same mechanics as a 1626UH, sans UV LED lamps and UV resistant lines. With all the auto-shut downs (about 7 while trying to figure things out) it seems I may...

    "Powering down" upon sensing media.

    Think it's fixed (so to speak). Cleaned the PF encoder disc (lightly dusty). Also noticed that I still had my left side cover off (perhaps the encoder needs darkness?). Printer is working fine now. Not that it's actually printing. I bought this printer off of auction, sight unseen. Lines were...

    "Powering down" upon sensing media.

    My tech asked me to plug directly to the wall to eliminate the UPS. This time I got an error! (sarcastic excitement) E095Err PF Drv Err Maintenance Manual says: 1. Is the weight of the media used within the recommended weight? 2. Is there paper jam around Grid roller? 3. Doesn't PF motor get...

    "Powering down" upon sensing media.

    My local tech asked me to do some general inspection of obstructions, and clean the encoder (Did not clean the reader yet. I believe that requires removing the carriage board). But I may be on to something worse regardless. After poking around for easy movement, and cleaning the strip, the...

    "Powering down" upon sensing media.

    One question. As a first time Mutoh owner, it seems odd to have a printer shut itself off without its doing so pointing to the printer attempting to "not damage itself". As in, it's experiencing a dangerous voltage and such. As I'm cleaning and poking around, re-powering the printer, seeing...

    Thanks FatCat. Will do.

    "Powering down" upon sensing media.

    I had my carriage over in the maintenance side/left for several minutes with the printer turned off, unplugged, and button pushed several times. Power up the printer up. The printer does its cleaning routine. Nothing suspicious. Upon "sensing media" the head carriage quickly but softly stops and...

    Hard earned ValueJet air leak solved (photos).

    Correction: The zip ties can be done without the carriage board removed (it's tight). I happened to notice the issue when checking to see if my three-way valve (under the board) was leaking air.

    Hard earned ValueJet air leak solved (photos).

    The issue was the Yellow & Black (4 color) also White & Cleaner (5 color) Y-connectors leading to the dampers. After many hours on and off and many long letters to my tech describing an exotic air leak (air noise at the head/cap), I finally have an air tight printer (VJ-1617H). The...

    Source for "plug replacement" (ink adapter/cart rubber seal)

    I'm diagnosing an air leak on a recently purchased/used VJ-1617 and I believe I've isolated the air leak to the adapters (similar ink set up 1638, 1324, and 1638). I got one "plug replacement" error upon a recent boot. My assumption is all of the plugs are old. I can't find a source to...

    1624 Dampers

    I'd remove the head keeping the plate on. When screwing on the fittings to the new dampers, you might wish to orient them so that they, when torqued a 1/4 turn to not end up under stress causing them to want to untwist. In other words, look at the destination of the line "as a relaxed line"...

    Question STS MP11 (for VJ-1617H) Reviews Needed

    Ran into a possible bad head and went to other projects. New head going in withing the next three weeks still have cleaning fluid in the machine (homebrew). the MP-31, you mentioned switching to this ink requiring a conversion. What does this entail. Is it not a straight forward flush and swap?
