Extreme Unclog Epson Printhead WorkForce WF-3640 Fix 0x97 0xEA Error

We removed and ultrasonically cleaned an Epson Precisioncore WorkForce WF-3640 and then convert it into a dye printer.

[@lisale8507]

Great instructions. I like how you stopped the video and circled areas of interest, how you explain each step, and show errors encountered along the way. Since I don't have an ultrasonic cleaner, I soaked the pieces in a small container of hot water. Over the course of a couple days I would swish the head pieces around in the water bath and replace the water. I then used a syringe to push through any remaining dried ink, and then used a can of compressed air to dry the pieces. After putting it all together again (and thanks for the reverse instructions!), I was able to print a nozzle check page. It's going to take a couple more head cleanings and one replacement cartridge (now the machine doesn't recognize the magenta cartridge, which was low anyway) - but it's working! Really happy that, at least for now, we don't have to replace the entire unit. Thank you for taking the time to put this all together.

[@BCHTechnologies]

Glad to hear that it worked out! It's great to know that the instructions were helpful.

[@celsiusswatt6021]

I tried to unclog the printhead from Epson R280 - first with traditional methods (using cleaning liquid and syringe dumping the liquid into the pad below the head). I managed to unclog some nozzles. Then i tried to clean the head with soaking it into isopropyl alcohol (as some others on youtube suggested). I was able to unclog about 80% of the nozzles. Then I read about using ultrasonic cleaners and ordered one. I was rather cautious, and did not soak entire head - only the nozzle side. About 1 minute was sufficient to kill the printhead. The ultrasonic destroyed the glue layer which attaches the nozzle plate to glass piezo substrate. As the result, while few more nozzles were unclogged, the ink chambers now leak into each other and the head is not usable. The water fed into in ink port gets out through another. I removed the bracket holding the nozzle plate - and to my surprise, I was able to take it off... I am not sure if the problem was caused by the solvent or the age of the printhead - but before ultrasonic stage the leakage did not happen. I will post the pictures later showing the head internals and the effect of ultrasonic cleaning. But for Epson heads it is certainly a head killer. Maybe BCH will tell how the glue layer may be restored?

[@purrl-adeaf-initelyspecial5509]

My Epson Workforce WF-3640 was from Costco and had an additional white ribbon connector (so three total), but with your very clear and detailed directions I was able to mark the ribbon ends so I would know what went where, and continue with the process. It worked eventually. I had to clean the printer heads and run test papers 5 times. I still don't have 100% clear lines on the test runs, but at least the Error Code 97 is gone and I am printing again. I used armed up denatured alcohol instead of window cleaner. It worked just fine. So much ink came out. Gosh the ports were clogged to heck and back. Thank you so much for this and for your generosity to the Epson Owner Community.

[@deent5186]

What kind of liquid did you put in the ultrasonic cleaner?

[@sck2012-universe]

OMG. you have NOOOOO idea what this video did for me. I have the WF3640 and literally NOTHING worked. The error 0xEA was stopping me from using my printer completely. And because of your very simplified instructions, I was able to completely flush out & clean all the hardware to now hopefully get my stupid printer working again. Thank you so so much. This was so helpful!!

[@marcelogancedo8766]

Hi, which liquid you used for the ultrasonic?

[@MB0807US]

I was ready to trash my Epson Workforce WF-7610 printer. The print head was completely clogged - even after several cleaning cycles (which depleted couple sets of new ink cartridges) and even trying those cleaning kits on eBay with a syringe, tube and fluid, the printer just "printed" blank sheets. I came across your video, followed your instructions to the "T" and assembled everything back. After running just 1 cleaning cycle, I was so surprised to see all 4 color lines on the nozzle check. Two more cleaning cycles and the color copies looking wonderful! I get a paper jam error during printing with the paper getting stuck just under the rollers near the print head rails - I presume some rollers may have got wet. Will dry the unit for a day and try again. Kevin - you are awesome!

[@kevinparrott1770]

Great video. I pulled mine apart and did my best to clean it. Didn't have an ultrasonic cleaner but did push cleaner through the print head with the syringe to confirm all were clear. Note that one was extremely clogged and originally didn't print anything on the nozzle check. Still not printing 100%. Suspect there is still air and/or cleaning fluid somewhere in the system . Will run through a couple of cleaning cycles again.

[@npcDroneClass]

we are officially at the point where epson print heads now only cost $20... back in 2018, they were about $160, lucky if you could find it for at lealst $100 or 89, then one day they hit $65... and now... $20 :3 it's a good idea to have it replaced once a year, also ease up on head cleanings, you'll ruin your capping station.

[@armarra]

Oh.... Well then, $20 isn't too bad.. perhaps get two spare and clean them while other is Being used. They don't swap over that easily but at $20 a pop you could afford to drop them into cleaning fluid in an ultrasonic cleaner as is..may as well save on that at least for a hands off clean.

Hey Kevin’s. My husband and I did this deep cleaning, with the help of your video. Thanks for that. My problem now is I keep getting an error 0x9e on my WF 3640. It’s great that this is exactly the model I have. I figured maybe it’s just not getting enough ink yet?? Most everything I’ve looked at is saying it’s about a jam or something involving a previous print job. 🤷🏼‍♀️ Any help would be much appreciated.

I have always used Epson ink in my WF-3640 with the exception of one time. The black ink worked for a couple weeks, then clogged up. I did a few head cleanings from the control panel, then replaced the black ink with Epson ink. After a few more head cleanings and letting the machine set for a day, I tried printing again. I could see black ink this time, though a little light. After one more head cleaning, voilá, it was perfect. I will never use any ink but Epson in my WF-3640.

Thanks for the video! If someone is using this printer constantly it would probably be a great printer. But, if not and the ink starts to set up…. I don’t have a sonic cleaner sitting around and to send it in for repair costs more than the dang thing is worth. Just a bad design. You should be able to flush the ink out of the ports if it isn’t going to be used constantly. Sadly mine is going in the recycle bin.

Excellent.. I have the same model with power and red light inside powerboats but nothing bon control panel. Power supply has correct voltages and power button is connecting fine.. however no lights at all and no display... perhaps transistors on mb. I like your videos very helpful. I wonder if with all the work to unclog the print head ..if it's worth having a spare head cleaned and ready to swap over.. trouble is they don't swap quickly however quicker than unclogging on the fly..

[@joetylerdale]

Great Tutorial! Epson can be the worst in clogging. We had a Epson GS6000, 60" printer at work and Epson sold a black Ink that cause the printhead to clog FOREVER. They replaced the heads on a many owners after they could not hide the fact anymore, but the us bastards, that found this problem after the offer expired were out of luck. I had gone thru 3 of this line (WorkForce) before I realized how stupid I was to be loyal to them!

I have the same printer. I'm going to try this.

I have problems with all of the colors. ugh!

[@patriot5548]

3 Epson printers later, I am done with them, they all clog and then are a brick. The latest was a p400 and within one year, banding, and then the inevitable CYAN jet clog. I switched to Canon, I hope that is better. I always used OEM inks, was careful, but the Epson still clogged.

[@christinegilligan1723]

So i just did everything in this video and im hoping it worked so far its not good . At first nothing came out on the nozzle check page so i did the cleaning that the machine does and then print the nozzle check and some black came out. I repeated and no change. Waited an hour did it again no change. I had to stop for now because i need more ink. Is it normal to go through so much ink during this process? Where is all the ink going? This is 2 sets of new ink cartridges i went through since working on this machine

[@fbatista1973]

Isn't there a problem to submerge the printing head in water (in the ultrasound cleaner)? Won't it damage the circuit board?

[@edemunsta]

Circuit board will be fine as long as it is completely dry before use. As long as you blow out the excess water and then let it air dry for a few hours board will be fine. 😉

[@johorangmo4779]

Never a problem .....watch makers run circuits through sonic's all the time.

[@GraemePayne1967Marine]

when circuit boards are made, cleaning in a water solution happens several times. Just make sure it is DRY before putting back in use.

[@Gavichap]

@CANBR First, don't use tap water. Use distilled/deionised instead. Then dry the printhead assembly thoroughly and leave it in the oven at *MAX 40°C* for 20 minutes.
