Introduction [0:00]
The video addresses the common B200 error encountered on Canon inkjet printers, particularly the MX922 model, which signals a problem with the printhead. Instead of immediately replacing the printhead or the entire printer, the video offers practical solutions to try and revive the printer. The presenter shares his experiences and methods to resolve this issue, emphasizing cost-saving measures for those facing expensive printer repairs.
Temporary Error Code Hack [1:06]
The initial method involves a hack to temporarily clear the B200 error code, allowing the printer to run cleaning cycles. This process includes turning off the printer, opening both the document and ink covers, and then turning the printer back on. As the ink cartridge moves, the user must close the cover before it reaches the left side. This may require several attempts to get the timing right, but if successful, it clears the error code, enabling the printer to perform cleaning cycles and resume printing. However, it's noted that this fix is temporary, and the error code may reappear later.
Printhead Removal and Cleaning [2:04]
To address the recurring B200 error, the video demonstrates how to manually remove and clean the printhead. This involves turning on the printer, opening the document and ink covers, removing the ink cartridges, and holding the stop button until the printhead cartridge moves to the correct position. The printhead is then carefully removed by pinching the center tab and pulling it out, with the option of using needle-nose pliers for better grip. Once removed, the printhead is rinsed under warm water to remove excess ink and soaked in rubbing alcohol to loosen stubborn ink, taking care to avoid damaging the green circuit board. After thorough cleaning, the printhead is left to dry overnight before being reinserted into the printer.
Printhead Reinstallation and Final Steps [3:40]
The final part of the process involves reinserting the dried printhead back into the carriage, ensuring the green circuit board faces up. The printhead is gently slid back into place, and the carriage tray lever is pushed back to lock it in. After closing the inner cover and reinserting the ink cartridges, the printer should start working again. The presenter mentions that reseating the printhead can also resolve incorrect printhead errors. While the long-term effectiveness of this method is uncertain, it offers a cost-effective solution to avoid replacing the printhead or the entire printer.
