Easy fix for Canon Pixma C000 Error 

It's 4 years since you posted this solution Tom. I had the C000 error on my Canon MX926, and cleaned and reseated the printhead and cartridges without success. When you identified the problem as the stuck printhead lock by the two cartridges visible at the front because the printhead couldn't return fully, I realised this was my problem. I followed your instructions, and problem solved! THANK YOU so much for taking the trouble to post. I was about to send the printer to trash, all for the sake of a bit of white plastic that didn't duck it's head at the right time. :-). So pleased !!

MX920 users, the printhead lock is the white spinnable cog. Turn it until you can push the print head all the way across. Thanks MR TOM, you sorted my problem.

THANK YOU!! This was the problem! My current 2023 printer is the Pixma TS6420. The printhead lock is a long white lever in the same area shown in your example in the video. Luckily it was reachable from the front (with the hood up) without even having to remove the side cover.

Thank you for this! Fixed in seconds. I was able to move my ink to the left, reach in, and fix this issue without removing the side panel for my Canon MX922 as it was visible from the front.

Thank you! not only did you save me time but also saved the printer from polluting a landfill. 🙏

Confirmed canon PIXMA mx922 c000. This fixed it. You’re a blessing. Thank you.

Thank you Tom! I did it! I fixed my computer! Mine is a different model and I did have to remove two small screws, but I was able to pop off the side panel, and I pushed the ink cartridge back in place. Easy Peasy! I turned it on and no C000 code! Yay! Now I was able to replace my empty ink cartridges and print out my paper! Thank you! Thank you!

Thank you so much!! My TS6120 stopped working this morning and the “what to do” page from Canon is a waste of time. Mine had 3 screws holding the side panel on but it was super easy to fix with your video, You saved me.

This was posted in 2017. Its 2021 and it just saved my Pixma ip7250! Thank you Mr. Tom.

Thanks so much. With your help I fixed my Pixma 922. Had a little trouble getting the stop button to lock down. Discovered I had to rotate white gear first, then it locked down.

Had the same error (MX922). Thanks for the video! After removing the panel, I realized the ink carriage was restricted in movement not because of the pin, rather, one of the ink cartridges was not seated properly and would bump against the internal housing geometry, preventing free movement of the carriage.

thank you so much for this video. it helped!! the lock wouldn’t go down all the way at first, kept popping back up slightly but after wiggling the printer head around and sliding it back and forth, worked like a charm.

I have a Canon TS8020. That C000 error was driving me crazy. Those two white screws inside were the main problem (I believe one of them came off), and the ink cartridges were not going fully over to the right side. Thanks for the video!!

Thank you for posting this! I spent long time trying to figure out and it was difficult to google. In my Canon Pixma MG5550 there is no little plastic piece, but instead what seemed to be a whole cradle needed to be pulled by hand. Also pulling it when the printer was off had no effect. It worked only when it was attempting printing.

Thank you Tom! I had 9 months with my printer put away. All working properly now! :) :

Thanks a Billion! The only difference on our Canon MX922 is that there is two Phillip screws on the back of the printer that need to be removed instead of tabs to be depressed. Other than that, PERFECT! Thank you sir!

After I pulled the side panel off my mx922, slightly different than yours, it also has 2 screws in the back that had to be taken out, I wasn't sure where the printhead lock was and didn't find anything like what you had that could be pushed down. I just had to unmount the new cartridge I had just put in and set it back in again. The cartridge didn't want to snap in place.

You're a friggin genius

I was going to take the side panel off to attempt this but I moved the print head to the middle, removed each printer cartridge, then placed back and pushed all the way to the right. It fixed the problem. Go figure!

Thank"s for the one solution fixing my unit

I love this video. I have a Canon PIXMA 922 .I had tried this solution. It did not work. Engineer Now I have an error 5100 when there is no paper jammed anywhere. I don't know what to do. I know when I turn on the printer there is this weird grinding noise sounds like some portion of the printing is stuck. I can't troubleshoot it with the maintenance menu. Every time I turn it on it has the same message it is also telling me to check the ink cartridges to make sure they are in place. I am unable to access all of them as they are not accessible. This all started when I installed new ink cartridges. Before this I had no problems with this printer. What really bothers me about Canon you are supposed to be able to pay for $25.00 for support. All you are supposed to do is sign in create an account and request support. It is impossible. I had purchased a new printer a while ago (which I returned I wasn't able to register it. Their site is not user friendly. All they want to do is sell you products. There was a time when you could get support even if out of warranty. Now it is impossible. If anyone out there has any solutions to my problem please respond. I want to keep my printer. I just need to be able to use it. Thank you. If the Person who created this wonderful very helpful video can respond I would appreciate it. I have many documents to print. Thank all of the community. Best. Gail

Tom, thank you SO MUCH for sharing this easy fix! When my copier fritzed out, I was at my wit's end as I'd just bought a bunch of printer supplies and was trying to print out a huge report for a client. Despite being terrified I'd bust the plastic shell trying to open the printer up, I persevered and was astonished to find not only an ink cartridge displacement but a piece of paper crunched up in the back that wasn't visible just peering down the paper tray track. Once the paper was removed, the cartridge repositioned, and the printhead lock pressed back down, I was back in business! Again, MANY thanks for saving my sanity and this print job!!!

Thanks for posting your video! All working properly now! :) :)

This actually worked!! Thanks for saving my printer from the dumpster :-)

Thank you so much for sharing this.

Well i had high hopes that this video was going to solve my C000 error, but i already had corrected that situation so the head fully travels left and right. My error seems to trigger when the printer trys to print after the inking.

Ha! Das war so hilfreich! Danke!

I wish you had started your video with the side panel in place so I could see exactly what you did to remove the panel . I cannot figure out how to unlock my side panel without fear of breaking the plastic covering. I've located a couple of slots to insert the screwdriver into on the rear of the panel but not one that releases it near the front of the panel.

Had a similar problem with MX922. Same C000 code, but all it needed was for one of the ink tanks to be removed and reinstalled. Guessing that error just means the ink cartridge carriage can't return all the way home?

My print head gets into the lock position but when my printer starts hes moving a little bit and then gets stuck while trying to reach the center of the printer. Can you help me with that? So lock position works but its not gettimg away from that position.

Un Grand Merci chef 👍

123 how easy it can be :D Thanks man!

Yes yes yes!!! Thank you very much 🙏🙇‍♂️

Thanks Tom!

You're great, thanks!

yeah but what did you do to get to where you have it at the start of the video? how do you take off the covers? 😑

My MX922 had 2 screws on the right rear side that needed to be removed. Also the C000 code can be caused by an ink problem such as low ink or clogged head in which case it will need to be removed and cleaned

The error can also be caused by a small plastic gear which has come off. After encountering this error on my 18 month old printer and checking correct seating of cartridges and presence of foreign objects I found a small white plastic gear had fallen off inside under the printer 'rail' which appears to connect to the mechanism which controls the part which seals the cartridges when the printer is not operating. After working out the correct alignment I pushed the plastic gear back onto the end of a rod (there was nowhere else it could have come from) the printer started to work again without error.

Thank you, it worked

Please Sir, can you help me to fix P10 error on my Canon printer pixma G2411?

thank you for posting it but i was not able to remove the side panel of my canon pixma mg6850. i wish you had started the video with the side panel in place.

Thank you!!!

Thx so much!!!

Thanks for the straightforward dissasembly tutorial - i found this printer on the street with this error - for mine, it wasnt the carriage lock, it was one of the print cartridges on the hidden left side had popped out, but there's no way to know this unless you are looking straight down the line from the side hole opened by the panel removal - had to stick a screwdriver through the top while pulling on it to get it to clear, cause it was the Pink/Red one on the... far left (of course it is...) Since your video helped me so effortlessly, here's some not-so-easy-to-find-info on how to prevent Bill Gates and his covid19 trojan remote exploit from affecting you and anyone you might care about - if you dont find this info agreeable, please punt it to someone who would appreciate it more so here's the how and the why on 5G and Covid19 and how together they'll murder you if you just go to the mall - try to find a way to shield yourself from 5G frequencies (6ghz in usa for now) - reason being, everything in this universe has a harmonic, including me you and viruses. when you get a physical virus, the harmonic gets added like a musical note to your bio-magnetic field. However, it also works the other way, if you know the virus harmonic signature (which is basically just a wave pattern EM pulse), you can beam it to someone's aura via EM radiation, and the body starts to experience the exact same symptoms as if the physical virus was there! (a counter-wave broadcast therapy would work to tune it out of your aura, if you have the source code and the apropriate radionic equipment on hand.) and now you know how bill gates made the physical virus and was planning on using 5g when it was globally up to remote exploit the death of millions, all while making it seem like it was the shitty ass coronovirus that cant do jack, all along. Cruise ships have installed 5g very recently, and they've been using those poor folks as bio-weapon lab rats. Oh, and this is why they are ordering '6ft' by draconian diktat: if 2 auras are close together, they interact and form random magnetic harmonies, like in a dialog - neither person can be infected in this state if they're being virus-beamed: the virus cant get a clear phase lock to sync to in either person due to the distortion - trojan remote upload fail. Buuut..... at 6ft away, your aura is out of dual-interference range...and vulnerable like a 6th grader at a High School party sponsored by some tall lady who goes by the name "Jill" Epstein and looks very familiar. So, use shielding, grounding, and im looking at literally 'metallic clothing' possibly even slightly powered like an antenna, so any EM radiation is attracted straight to the mesh, energy always seeks to travel through the path of least resistence, so a metal mesh powered with an EM field is more attractive to the waves than just a metal mesh - just have something to send it to for a ground, like LEDs or small motor, so the waves sync with your metallic aspects instead of your own magnetic aura field - basically you'll have to become a mini radio receiver/transmitter that trolls their beam triangulation tactics - cause they already know where you are via your phone, but they're not targeting your phone's antenna.

lifesaver!

Hey, you know how to fix canon pixma 5C20 error?

video does not show how to open the side panel and I cannot find a way to open it.

Same problem as many of you not knowing how to get the side panel off!

Nope, I still have C000, have done all the other checks and my cartridges can go all the way to the right. What next?

so why does it happen..

Also work for canon 5200 error code. Thanks!!!

but the problem back

Great video/suggestion. I'd love to try it on my Pixma MG5620, but can't see how to get the side off. Suggestions, anyone?!

لم أر ما فعلته للتتخلص من الخطأ c000

I’m buggered if I know how you got that fucking cover off. Start from the beginning or don’t bother.
