A Canon PIXMA TS9521C whose firmware update will not install, fails partway or is not offered has a connection or a procedure issue, and an update is worth completing because firmware keeps a printer working with current systems. The TS9521C is a crafting and photo inkjet all-in-one that prints at up to 12 by 12 inches borderless, with multiple ink tanks and wireless and USB connection. Canon issues firmware for such printers to fix faults, improve security and keep compatibility, and the update is applied either by the printer itself over Wi-Fi or by a program on a computer.
The checks in more detail
The simplest route is from the printer. Make sure it is connected to Wi-Fi and the internet; check the network status in the settings. From the printer's menu, open Settings, Device settings, and look for the firmware update option, choose to check for an update, and follow the prompts if one is found. Keep the printer on, with the power cable connected, and do not touch it or turn it off during the update, which may take several minutes and restarts the printer.
A message appears when it is finished. If the printer does not offer an update, or the over-the-air update fails, use the Canon PRINT app or Canon's support page for the printer. On the support page, enter the model, choose your operating system and download the firmware update tool, then run it with the printer connected by USB or the network as the instructions say, and follow the steps. Close other print jobs and programs first, disable a VPN or a strict firewall during the update,
and make sure the printer has no error, such as a paper jam or an ink alert, since an error blocks updating. If an update fails, restart the printer and the router and try again; a weak Wi-Fi signal is a common cause, so move the printer closer to the router or use a USB cable. Do not interrupt the process. If the printer will not complete an update after several attempts, contact Canon support with the model, the firmware version and the serial number.
