B200 means the printhead has failed. A reset will not repair the printhead. You need a new print head which I think is nowhere to be found.

A google translation to Chinese:
B200表示打印头出现故障。 重置不会修复打印头。 您需要一个新的打印头,我认为找不到它了。

Edit:
You may be able to source either a new print head or a refurbished one from Shen Zhen, China. Have a search on eBay and you may be lucky

您也许可以从中国深圳采购新的打印头或翻新的打印头。 在eBay上进行搜索,您可能很幸运

Refurbished print heads out of China are not very reliable and therefore should not be recommended here, you got a better chance playing the Lotto..

Not a recommendation just a comment. Buyers need to exercise due diligence in the purchase of any product from any country, including the UK!

I can only speak of my own experience with HP printhead replacement from China and Cationic UV printer spares again refurbished which I found to be perfectly acceptable.

Interestingly a new print head again from Shenzhen (maybe the original manufacturer for all we know) can be purchased for between £50-£60

Obviously, your own experience sounds to be based on a poor outcome?

Seems I was looking at the 8500, 9950 and Pro9000 @£54.00. Not sure if this link will show as the last one edited and removed

Anyway, Canon has had long links with China for the manufacture of printers etc. Starting I think in Taiwan in the 1970's and up to 2010 printers manufactured in Thailand and Vietnam. After that time I believe China with Canon Finetech Nisca (Shenzhen) for business machines, printers, and peripherals along with Taiwan. I suspect that the parts are all manufactured in China even if assembly and distribution elsewhere

If the required parts not available in other countries China would seem to be a logical place to look. Assuming that the printer is worth restoring age and general condition etc.

Hello jbhtjbht


Every printhead of canon printheads have a eeprom on the back side of the green pcb with the golden contacts. That eeprom got corrupt and you have a B200 error.
reprogramming that eeprom solves the problem.
What you need is the original hexdump of that eeprom.
You can print it out with a ""service tool"" for canon loaded in your PC .
Also set your printer in sevice mode . How to do that for your printer use Google .
This only works on printers who are without any errors.
So I advice everyone to print out the hexdump when your printer is in good condission . Whenever your eeprom got corrupt you can always reprogram that eeprom by a electronic engineer. It is cheaper dan bying a new printhead.
Not only the printhead has a eeprom also the mainboard in de printer has one.
The printout gives also this information.

as I said service tool does not work with a defect printer so you have to buy a new
printhead to solve the B200 problem.
advice :make a printout when printer is without errors and store the printout of the hexdump for later use. You will never know you need it in the future.
