If the Canon MG6640 printer is locked and you can not find a way to reset the diaper overflow error and error 5B00 or you tried to reset this error and killed the service mode in the printer, the 25Q32 and 25Q128 chip dumps complete with the programmer will help solve the problem with the error.
Files are likely to be more useful to the service center staff or printer repair shop, perhaps you just know who has the programmer. The files are checked and 100% working.
AND ALWAYS LEAVE A REVIEW ON PURCHASE !!! THANK YOU!!!
