Trying to read the service guide for the controller board was a bloody nightmare, just decided to print targeting crosshairs for head alignment as the built-in patterns were just awful. Got things within 2/180th of an inch then used built in patterns. Had issues with bad sealing on capping...

This is the wanted to buy forum. :rolleyes: Also, 2025-2020=5

Finally bit the bullet and decided to get a dedicated UVDTF Haolic branded printer instead of printing films on the JFX200. Holy hell, buying a used, rusted Chinese printer was a saga. Took a gamble at $500 and it looks like it spent a few days outside. Control board kit alone was worth that...

Sounds like there might be air getting into the white circulation loops if I were to hazard a guess. I'd be willing to bet on the pumps myself.

If the temperature swing is big enough, you might be getting condensation in other parts of the printer. That can cause MAJOR (expensive) issues if that water builds up in moving parts or electronics. Might want to invest in heating the room containing the printer.

Not a helluva lot of difference between Roland and Mutoh on old DX4/5/7 head machines when it comes to things like parts to be honest. Older printers as well, expect to need more maintenance overall.

Not an electrical problem in the head, but with the carriage. Last time I saw a DX7 do that, it was slammed into the side of the machine due to an encoder failure. :)

If the nozzle plate is dirty or getting loose, it can cause deflection.

Leaning towards mechanical but probably needs a head regardless. If the head is already new, might be a big red flag.

Virtually every black nozzle on a head deflecting, either something wonky is going on electrically, or might've been something that bonked the printhead if I were to take a stab at it. New head would likely fix the issue, so budget accordingly if you plan on getting it.

Sounds like a service manual might be in order.

Nozzles are there, but that is a LOT of deflection on the black.

Might want to change your capping station, looks like condensation or something. I have seen cases where that happens when the cap doesn't seal right. The evaporating solvent from the ink chills the head nozzle plate and cools it causing humidity to condense on it. Tends to happen in higher...

Defective heads tend to show their defects really quickly, within seconds to days in most cases. On top of that, the seller has zero control over a new Epson printhead. Heads in general tend to get almost no warranty, as ink can be a huge variable in how long a head lasts. Combine that with...

This is the classifieds section, might want to hit the search before double-posting new threads. Roland section is here: https://www.signs101.com/forums/roland.193/ Welcome to Signs101. =)

Yeah, DX5s are just obscene in price for what they are.

If you haven't already, try doing a nozzle wash.

Black is usually printed using all colors for 'rich black' and missing black nozzles will make the black look weird.

UV is a differnet smell. As for durability, UV for me has been way better than solvent. But ink formulation is far more varied in UV. I love being able to print on material that isn't coated to take ink. Metallic films and such just don't print without being smudgy messes on some plastics...

Could be ink starvation due to a bad damper.
