Epson DX4 Print head replacement - Cleaning - Installation

This video about the Epson DX4 solvent print head.
The head is taken apart and magnified with a microscope to see it's composition and reason for deflection. Also shown is the process to remove/replace a head and brief over a few cleaning and adjustment procedures before and after.
Printers: Roland SP 300-v (2 heads) and Roland Soljet Pro II SC-540 (6heads).
Be certain the power cord is disconnected before servicing. And press power button 'on' three times to drain residuals.
If anyone has more advice, please post.

No one on the internet shows how to complete the installation by adjustment via bias and software. That would save my life if they did!

Thank you for all your information

[@EMILIEN790]

as a Roland technician i can say SP-model printers are most simple and reliable machines. Love it😊

[@jetskidetailing8617]

Indeed, and I agree.

[@bobhuddleston8883]

Can you post a video that gives more detail on exactly how to adjust the bias and exactly how to do the software adjustments?

Actually, the material below is in fact not quartz, but silicon. It wasn't cut using a laser. Better yet, it was made by etching the pattern

I am using an cheap canon MG2577S printer which belongs to MG2500. It comes with non reusable cartridges which I filled 3 times and after that it clogged. I tested the printer ink in my fountain pen ,I found that it dries faster and pigments stick all over the ink cartridge of my cheapf ountain pen. I found that these inks are designed to clog. Also the cartridge life is less its designed to be like that. I want to try out of the box things the only available water soluble ink I can get is cheap or expensive fountain pen inks which is water soluble while most printer inks are not that soluble in water.

Hi, Great video and thanks for posting it. I'm right in the middle of try to bring back a Roland SC-540 that was printing the test print perfect about 3 months ago but how is not good I only have Cyan with a little black. have started with a head soak but looks like I will have to do a complete flush out of the heads like you did. have been looking online for the service book But no luck at all. Thank God I found your video as was about to take the heads out and see you have to do a head calibration print sheet. lucky right😱 Any chance you can help out with a service book...Please or how to enter that mode. Cheers from Tasmania.👋

Hi, which cleaning fluid did you use and did you soak the head 1st? Thanks

[@jetskidetailing8617]

Hello Nuno, did extensive soak and cleaning, however the head was at end of life. Used regular/standard cleaning fluid.

bravo

Whats up brother do you have any videos working on your sc545? I have one right now that I am trying to unclog the lines and bring back to life.

[@jetskidetailing8617]

Is it the ink lines that are clogged? I back-flushed the ones in this video and went perfectly. The SP is the same as the SC, just more heads and parts, though basically the same machine to work on as I've serviced both. And to mention, I pulled all the circuit boards from my SC at one point and cleaned them all up before reinstalling.

I notices on the XC-540 you did not put the pressure plate on top of the dampers, is there a reason for that? There is a sponge on this pressure plate that does not cover all dampers and I always felt this plate was bad engineering

[@jetskidetailing8617]

@@impressionstitan1561 It was left off during the calibration setup so that the heads could be moved with the hex-key and thumb-screw. Once calibration was completed, the pressure plate was reinstalled :)
