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?

My 3-year old MG7520 spit out the B203 Code today. It's a great printer and I hate to lose it. Removed the print head and cleaned it. No luck. Called support and they were of no help (told me I had corrupt drivers). Tried the Machine Off - Lid Open - Machine On - Close Lid method. Wow, it worked for me . Like others who have posted, there is no telling how long the fix will work. But for now I am printing. Agree that Canon ought to put this fix out there for all those frustrated by the dreaded B203 Error Code.

My printer is MG 7760.

Had increasing trouble with the clarity of print so after trying everything else I removed the printing head and washed it thoroughly and replaced. I tried the same method of opening the top, turning it on, then closing, and it did go through a routine. When I tried to print, it ground away in its routine for a while but eventually came up with the B203 message again. 

I will leave it for a while and try again later but if it doesn't work I'll have to get a new printer. Why does Canon say to take it to a service agent when it's obvious that the only advice you will get is to buy a new printer - and what do I then do with the spare cartidges on the shelf, if the new printer is different?

I tried the method. It cleared the error. But once I tried to print again (Macbook Pro wireless), it came back. Unable to print.

Any other suggestions?

Mine cleared and I am able to print. However, the print quality is way below par. Somewhat similar to the Draft Setting. Thought I would bite the bullet and get another printer. But try to find one that rates above 3 stars and you will need several cups of coffee. Seems like everything available is just slightly better than junk.

Exactly. And I refuse to buy an HP. Swore off them 4 years ago with their tech support mantra, "no worries, just buy another one."

I'm afraid I've given up and bought a new printer -  a Brother model, recommended by an IT-savvy friend. I was warned not to touch HP.

Like others who have commented on this thread, my MG7520 also just stopped working with a B203 error code after 3 years. Contacted Canon Phone Support and they confirmed it was cheaper to buy a replacement than trying to repair.  In fact, they have an "upgrade" program setup to offer a new printer at a discount to replace the non-functional one.  Apparently these models Canon is selling are disposable printers. So I bought another disposable printer to get me thru next few months while I shop for another more reliable longer term solution.

My understanding is that this problem is due to a clogged print head, which makes sense in my case because I hadn't used my printer in over a month because I had run out of black ink.  I had just purchased new ink for it and after installing, I got the B203 error.  

I removed the print head following the instructions here.  I then removed the oval shaped gaskets from the printhead where the ink wells seat against the printhead.  Using cotton swabs and alcohol, I cleaned the printhead thoroughly.

I put a drop of alcohol on the ink inlets (where the gaskets were) and using a syringe and a bit of tubing, I was able to force the alcohol into the printhead.  This got messy as the ink that was inside it was forced out the other side.  I cleaned up the mess and put the printhead back.  It was a bit tricky to get the printhead back in, but the instructions will help align things. 

Once everything was back together, I restarted the printer and ran a cleaning cycle.

In my case, I was actively using the printer and the print head was not clogged.  Produced good prints and picture up to 5 minutes before failing.  Service tech told me that he thought it was unlikely a clogged printhead but got overheated and some electronic component failed.  Even after sitting unused for several hours and manual hard reset, the printer produced this error on power-up.  I was also told by a store employee, a inkjet printer expected life is only about 2 years with occasional use.  Cost of replacing them at less than $100 is far cheaper than fixing them.  Hence as I said before, they are Disposable Printers.
