Advanced: Fixing Canon B200 printer error - if you've tried everything else 

After putting print head and cartridges back into printer, do not close those compartments. Leave them open. Plug the printer back in, power it on, and close everything back just as soon as the printer makes a noise to start powering on. Cleaning the print head as shown in this video was the only way to actually get all of the ink out of the print head. You can also clearly see if they're actually clean before you reassemble the print head. Leaving the compartment open and powering the printer on somehow allows the printer to see that the print head is no longer clogged. So both of these steps are necessary. Installing a new print head sometimes requires this same reset process. I put electrical tape over 2 of the electronic board contacts 2 years ago. It solved the B200 error, but I've been stuck printing in black and white since then. This video was the only one that really got everything clean! I'm printing in color again! Update: Removing the two screws works best with a small precision screwdriver. A normal small one will work too, but the precision driver allows you to turn the entire screwdriver without turning the base that is in the palm of your hand. One part turns while the base does not.

You did it man! My printer start giving me b200 error and i tried ultrasonic cleaning in printer head but left the ceramic attached to the socket and didn't solved the problem. After unscrewed it and injected isopropyl in each hole until all of them let light pass through it, the printer never showed the error again! Thank you very much!

I have a success story to share and it starts with pulling the printer back out of the garbage is how far it got. My wife wanted to try one last time as we hadn't tried the printer head removal for cleaning and have a box of assorted ink remaining that was pretty substantial. I started by retrieving the print head, loosening the screws per the video, the white portion folds down, the attached ribbon acts as a hinge, the white portion of the printer head dangles. l ran the white portion under tap water for probably 3 or 4 minutes, I also ran the black gasket I had previously pulled off under tap water. After dabbing the print head with trying to remove as much water as I could I reassembled, placed it in the printer and added all of the printer cartridges with ink. The first three or four times I tried to print or use some of the maintenance functions it failed but on the 5th time it began to work as ink was likely able to perfuse the printer head after the cleaning process. Again, thanks. The printer was already in the garbage before I retrieved it to fix it again.

Exactly what I needed. Great follow through on getting to the root cause. My MX870 WORKING!! PERFECTLY. YES must leave the compartment open on a restart.

This is the solution I needed, thank you! Our Canon MX870 was sitting idle for months, and this worked perfectly.

This is the one that fixed mine after I thought I had given the printer head a really good clean, but no essentially it was still blocked until I did this!

Thanks Cool BUT Another thing I believe we are missing is the "BED" of the printer heads, where they "SLEEP" when not in use, needs come cleaning. Observe where the printer cartridges/heads position themselves in their bed position when the printer is turned off. This area of the printer is where the heads rely on being clean and able to seal from ink drying out while not in use. While turned off, move the heads over so you can access this area. Use a flashlight to see well. Using a water-wet-moist paper towel/napkin, clean this area and any rubber flaps. Constantly turn the paper to a clean area until it is a dirty ball. Repeat with a new wet paper towel/napkin, up to like 5 of them. You'll never get all the ink to come off but at least the majority of it. This might be the reason our heads are drying out or clogging because we've never cleaned their "bed area". Yep Take care

Amazing and helpful, I tried everything, this finally fixed it :)

PERFECT SOLUTION, THANKS A LOT

Thanks for leaving out the hardest part, how did you remove the screws? I have just spent 15 minutes trying to use a screw driver and they don't budge. I don't mean to be rude but it is frustrating to see a solution that skips a major step. What did you use to loosen the screws?

Dude. How did you get those dang screws off. You would not believe how long I have been trying

merhaba lütfen bana buruna yardım bekliyorum ve ben şöyle anlatım ben canon mg6450 cihaz aldım ikinci el olarak aldım üzerindeki sağlam gibidi az hafif cizgili yazıyordu bende hafif ılık su ile temizledim ve sonuç yazmadı ve yazıyor gibi yazıyor boş kağıt çıkarıyor ben nerede hata yaptım bende onu çözemedim şimdilik yazmıyor boş çıkarıyor yaani bu soruna yardım edecek kişileri bekliyorum...

Hi I have the Canon Pro-10s and printhead part QY6-0085. I managed to unscrew the 2 screws however the design is different and the white flap will not simply flip open because it is attached to a long metal plate that won’t release, although it is now loose from removing the screws. Hard to say if I use force will it damage or is there some technique I’m missing, any idea?

Can you share a link to the replacement head you bought, any info would be good, thanks!

Ah unfortunately this didn't work for me. Wonder if it's the contacts on the printer head assembly that's causing the issue

How did you solve the screw? I can't untie it

Hi, they don't show how they cleaned it. Did you immerse the circuit board in alcohol?

Will this work with the Pixma MX892?

bought a brand new printer head for my mx870 and b2 error code showed up and cant clear it no matter what

(EDIT) DEU CERTO < TOP IRMAO , FUNCIONOU :DDDD

rien ne marche avec ma MG5250 mais si je l'allume avec le capot ouvert, et que je la ferme pendant qu'elle fait son cinéma, j'obtiens des impressions parfaites. Mais avant la première impression, je pense qu'elle fait un nettoyage, ce qui consomme de l'encre. merci ! Cela prouve qu'il s'agit bien d'une obsolescence programmée. ACHETEZ en FRANCE où l'obsolescence programmée est interdite. En Belgique, l'obsolescence programmée est encouragée par l'Etat pour faire marcher le commerce. Et qu'en est-il en Hollande? Merci !

FYI my error didn't fix after the shallow water soaking and drying. BUT then it worked a 2 weeks later when I tried it in the printer one last time! So be patient and know you may need to leave it dry for a week or 2. Take care
