MG7520 Error B203

[katana]

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?

I have had another reply suggesting that a firmware update has potentially fixed the B203 problem.

I am grateful to those who took the time to reply and amazed at the diversity of actions taken in order to gain a fix for this problem, however this same diversity probably indicates they are not a long term solution. Will this also be the fate of a firmware update? Do let me know. This whole senario is identical to the many other Canon Error codes, if you follow the other Posts. I am resigned to losing my DVD printing. Best regards to all. Dated 29/05/2020

What method.  I don't see it.  Thx

Thanks for the tip. works perfectly. Suggest you buy 3rd party ink which is dirt cheap and works fine - refill original cartridges so the printer thinks they are genuine.

Hello

I just had the same error B203 pop up on my MG7750 display.

I opened the printer cover and turned the printer off, then i turned it back on and as the printhead started moving i closed the printer cartridge cover.

I was now able to get into the printer menu on the printer itself, i went to setup and then did a reset all and after that i go thru the wifi setup on the printer. After that i did a firmware update. And after that a auto printhead allignment.

For now it works, but i wonder how long ?????

Regards Chris

To Fix Error B203 Check your ink cartridge:-

Turn off your printer and make sure all the ink cartridges are full. You can pull all the ink cartridges out of the printer and make sure there is plenty of ink in them. Refill the cartridge to resolve the error.Moreover, improper installation of ink tanks can also generate this precise printer issue. Make sure that’s not your case.

MG5750 giving E203 error code
Just followed the following method on my MG5750,  (other repsonses confirm this method may work on other models)
1. Switch Off Machine,
2. Open cover (so you can see cartridges)
3 Turn On Machine,
4. When cartridges start to move Close the Cover 
Works a treat "Well it did for me" dont know how long the fix will last for but so far so good.
THANKS

What a joke canon is.  I will NOT be spending any more money on their products.  Getting this code after getting the B204 code and following the prompts to fix. I hardly ever utilize color ink and it happens to be running low and now the entire unit is unusable, unreplaceable and JUNK. it is a SHAME that Canon allows this, just another piece of trash in tha landfill.  SHAME ON YOU CANON

I have had no problems since the firmware update. Fingers crossed. 

[kaylasnyder]

I will try this, thank you!

Worked for me: turn off, turn on with lid open, as soon as the cart moved, closed lid. loaded fine. before this happened 1 ink was low, i replaced it, but didn't fix the B203 error.
