Many of Epson printer's errors can be caused by a malfunctioning printhead lock. The lock prevents the printhead carriage from moving to the left. If a spring is loose, the printhead will display either "paper jam", or "cartridge door open" errors. We showed how the printhead lock works and how to test it. We also showed how to install a new one if necessary.

I want to compliment you on your “how-to video” making abilities, literally the very best instructional video ever. When you said at the start that you were going to show the issues as well as show how to replace it necessary I almost moved on because I thought there’s no way this dude can show all that in under 7 minutes and the information be of any use. You are quite efficient! You didn’t talk to fast and you explained and showed each detail in the process. Normally a fix like this would be a hour and a half video that would leave you brain dead at the end. Great job great video you’re awesome and I love you! Thanks for saving my printer:)

Thank you Kevin! I replaced my waste ink assembly today with the part you sent. The waste ink WF-3640 fit perfectly for the WF-7720 (just a longer waste hose like you said) I got to see a lot of you today watching your videos. The WF-7720 is up a printing better than ever. I found the spring at the bottom I guess thats why I was getting the cartridge door open error. I was also getting Error Code 000033 before and the new part fixed everything.

@kristinaray3269 Год назад

Great video! My lock doesn’t seem to be engaging fast enough. Like the timing is off. The carriage goes all the way to the left but the lock either doesn’t lock fast enough or it locks then unlocks. Then the carriage goes slamming back to the left! Any other ideas for me on this?

Kevin I need your help I have an XP-970 when starting up the printer seems to start fine then at the last second of its startup the carriage slams hard to the left and it gives a paper Jam error. I want to save this printer its new. If you could help me with it I would appreciate it.

@queenv754 2 года назад

Hey Kevin. My Epson 7710 had stop printing Magenta (sublimation) even after adding fresh ink and cartridges. So I did multiple print head cleans and still didn't work. Flushed nozzle with your solution. Only caused me to replace maintenance box. And Magenta still didn't print. Took print head out and cleaned according to your video and now the print head makes loud noise when going to left Error 00023. My ET 15000 which is brand new is doing the same after changing out the type of ink after flushing nozzles. So my conclusion is that after turning power off to manually move the print head is causing this. What do I need to do to relock or reposition the print head correctly after it has been manually unlocked and moving freely?

@reggiecosens9700 2 года назад

Hello Kevin I went to go do a print head cleaning on my Epson ET 2720 because I hadn't used it in awhile and it wasn't printing right. So the problem started when I went to do the cleaning and I broke the printer head locking mechanism. I went ahead and finished the cleaning and put the printer back together thinking maybe it would still print and work for the time being since I had a job I had to print still to get done and there was time constraints on the job. When I first started the printer up I went to go do a nozzle check I believe(I'm not 100% which I tried first)but once I went to do it I got an error once the printer went to unlock the print head mechanism like normal when starting the nozzle check. The error said check with support or something like that and there was a problem. After the error screen turned off I got it back to the main menu screen on the printer and I decided to try everything again thinking maybe it would still print but just fail to lock the printer head in place when needed. Well then after that if I go to nozzle check or try to print anything or do any other maintenances it doesn't give me the error. It goes about the process like normal and sounds normal. You can see and hear the print head moving around just as if it was printing but nothing ever gets printed out. No ink goes onto the paper anywhere. Did I mess up something else when cleaning the printer head or is this happening because the locking mechabnism is broke???? Please help me figure this out. I don't want to buy the new locking mechanism and take the time to fix it and have there be another problem that is causing it not to print as well. Thank you for your time and sorry for such a long post I appologize.

It’s hard to tell. Sounds like a bunch of errors mixed up. I can’t give a diagnosis without looking at it.

@bvnseven 2 года назад

Kevin, very good videos! I have an epson wf-3640 that the carriage goes to the far left when doing the startiup and I hear a screeching sound and it trips the 0XEA code. Turning the printer off and back on does not help. What causes this and how do I fix it??? Thank you.

@tylynblanchard4456 2 года назад

Mine is doing this same thing! Did you get it fixed? If so how?

@GenXMama Год назад

Following for answer

@bvnseven Год назад

@@tylynblanchard4456 check the plastic encoder strip that goes behind the printhead for dirt, grease or kinks. Clean it with a lint-free paper towel and water the length of the strip. If it is kinked you will need to get a new one. Keven has a video on that, easy to fix. I did it and it worked.

@gaet257 3 года назад

It's possible to remove printer lock definitely? And in Epson r300 is printer lock lever necessary? or can I remove it?

@BCHTechnologies 3 года назад

You can’t. The printer needs it to determine its printhead position. If you remove it you will get fake paper jam error.

It could be a few things. The worst one will be the main board. Since L805 is not an US model, it will be tough.

Hi Kevin. My Epson Workforce 645 has the error, "Printer Error Turn Power Off And Then On Again" but it doesn't move the print head. Do you know what the defect is?

@kdr-ql7pz 8 месяцев назад

Me too. When I went to clean the nozzles, I forgot to turn the power off. My guess is that the gearing mechanism is out of order and my locking action never happens. No noise in a gearing assembly makes me assume there is a binding action within the system. This is the exact reason I studied electrical engineering. The failure modes are less frequent, easier to fix, and last longer. Fixes with sw and fw are the true mechanism. 1. I'm going try moving the cartridge assembly completely to the rhs 2. Pull the locking tab outwards. 3. Move the belt until it locks 4. Re-engage the locking tab. 5. Turn it on I get so sick of the sh*t my wife brings home. Her friends always dump their waste on her. Why can't everything be electrical?
