This Canon MP495 is very sleepy...

Is there any way to stop a Canon MP495 multifunction inkjet printer from going to sleep? It has its own built in 802.11g/n network interface for sharing itself with the LAN, which works fine, until the printer snoozes and falls off the network...

The printer in question has a built in network interface. There's a piece of software in which you manually configure the printer (using a USB cable) to tell it the SSID and WPA2/AES PSK for the AP. This works fine. Clients on the same LAN segment as the printer can print to it.
The problem is that after about 15 or 20 minutes of inactivity, the printer goes to sleep, as evidenced by its top panel lights going out. If you wake it up again by pressing the 'reset' button or any other button, it gets a new DHCP lease and shows up on the network.
This power saving/sleep mode doesn't affect operations when it's used as a single computer printer in USB-connected mode, but when the goal is for multiple 802.11n clients to print to the same wireless connected printer, it's a real hassle to walk over to the printer and poke it to wake it up before sending a print job, every time.
Is there a power saving setting somewhere in the Canon utility software that I've missed? Or some other way to do the printer equivalent of using a cron job to 'touch' a file periodically?
