MG7520 Error B203

katana — Sat, 25 Jun 2016 17:23:54 GMT

Called Canon Support and they say it's unrepairable but past 1 year so unreplaceable too. Tried everything including dismantling the printhead assembly to manually clean. Barely used the printer, 1 or 2 prints a month.

Anyone have recommendation on non-Canon I can buy to replace for around the same price range?

Not only did it take me 8-12 hours of effort and no wireless printing ever happened, only direct connection, but 2 months after puchasing, I also got this code. What a waste of money and time. I probably printed in total 5 things from it. So lame.

I received this error and have spent hours trying to fix this. What has anyone else tried successfully.

Canon's response was to buy another printer. This one is only 2 years old. My last HP lasted 10 years and was still working great when i replaced it.

Same problem. 2 1/2 year old printer and Canon said it is unrepairable. It should have lasted more than 2 1/2 years. This will be my last Canon purchase.

My printer is only 2 1/2 years old and I got this error. Canon's answer is to buy another printer. Ok. I will go buy another HP as my last HP, that the Canon MG6620 replaced, lasted 10 years. I held on to the old HP for some unknown reason. I plugged it in tonight and with the exception of black ink being empty the HP still works.

Goodbye Canon.

I've got an MG6850 and i had the same error code.

I used to trust Canon but i don't now.

I followed some advice to open the maching then plug in and as the heads moved close the lid after that it worked.

I wonder how long for.

The inks are penomally expensive and difficult to get.

I have spent a lot of time and money on this product

My printer is just over 2 years old and has not worked well since I bought it and it's not much I've used It's so bad that it's easier to send what I need printede to my children and on their old HP printer, Print it out.
It has been 4 times for service and 2 times for repair and now it's out. Help code 203
i never want anything to do with canon again and want everyone who will hear me discourage to buy something that canon has produced
I feel like I've been crazy. to buy the produkt producer buy Canon.....

canon is terrible useless and a total waste of mone...

Use your money on a printer that does not come from Canon

or what you think of buying just do not! buy Canon

This worked for me also. Found this after calling Canon. Canon also told me it is not fixable.

I had this error also. Followed your method and it worked for me. Is your printer still working? If not, how much longer did it work?

What steps did you follow? My printer is sitting on the closet floor waiting for our County bulk trash day.

Re: MG7520 Error B203

turn off machine, Open the printer like you will be inserting ink cartridges, turn on printer, when the cartridge/printhead unit starts to move, close the printer. When I did it it did a self check for 3 to 4 minutes and when it was done it was ready to print.

Don't know if it will be a permanant fix as I don't know why it suddenly stopped working, but it is working now.

I also completed a Canon support survey when they sent me an email stating that they should be telling people to try this. If it doesn't work for them at least there was some type of effort.

Thank you. I will pull it out of the closet and give it a try. Canon offered me a discount on a new printer but I can't see throwing good money after bad. I have been using my now 11+ year old HP printer since the Canon died. I was disappointed that the Canon lasted only 18 months.

Worked for me too. I was about to trash it and buy another. Thank goodness I found this thread....can't believe Canon is of no help.Hoping the fix lasts awhile.

Mine is still working so far. Been 3 months or so.

Awesome to hear your printer is still working. I had moved mine to unplug it. I'm afraid to move it back to where I had it thinking maybe it'll stop working again. lol.

My mom just called me to tell me she was putting a couple ink cartridges in her canon printer and it made a funny noise and now she has an error message. I told her that happened to me too. I'll go over to help her out today.

I find it odd that this error is happening to people now and wonder if Canon is trying to get people to buy new printers. And funny how they don't share how to fix it. Thankful for this forum so we can help each other.

Thanks again for the solution.

Worked like a champ. Cheers!

I joined the forum because it gave me some ideas on how to possible get rid of the B203 error code for my 2 year old MG7520. I ended up upluging the printer from the wall outlet and the computer then turned the computer off. I waited untill the next morning, pluged the printer back into the wall and the computer and rebooted the Mac. I checked the make sure that the Mac was "seeing" the printer, which it was, so I decided the run a full and complete test pattern using the printer tools. Since it started to run the test pattern ( which it would not do the day before) I felt that was a good sign. Sure enough, after running the full test patterns, realigning the heads, etc., I hit the print icon on the Mac and it worked. As many have said though, for how long. I really enjoy the printer, so thanks for the help, and I hope this helps someone else. Ron
