The default passkey is "0000". Try that unless you selected a different code when setting up the printer.

For information on setting up a Canon printer for bluetooth, go to this link. In the search window in the center of the screen, type "bluetooth" and click the Search button. Select the "how do I print directly from a PDA. . ." and you will find directions for setting up the printer. Note that your PDA or cell phone must be compatible with the OPP or BIP protocols. (Check the specs on your unit.)

With my MX850 printer the bluetooth setup instructions were only in the on-screen printer manual, not with the bluetooth adapter, and not with the printer documentation.

In my case it didn't help as Windows is not discovering the bluetooth adapter for some reason.

My MP500 has a normal flat USB plug in.  Turn off your printer and just try plugging in a normal USB cable into that slot...You can use the printer cable if you want. Haven't rec'd the BU20 yet, but don't think it will be a problem.

The blinking B and C lights indicate that the black and color cartridges are low. This has nothing to do with the wi-fi issue that you are experiencing. If the alarm light is also lit or flashing, please add a comment with that information.

For the wireless network issue, your best bet may be to reset the network settings to the factory default. Press the Maintenance button repeatedly until the LED screen shows a "t". Then press the Color or Black button. See https://www.canon.co.uk/support/consumer_products/pixma_printer_wireless_connection_setup/mg3250_printer_wireless_connection_setup/ ; scroll down to see the reset information. After this step, if the network uses WPA or WPA2 security, press and hold the Maintenance button for approximately 5 seconds. The LED screen should show a bar at the bottom. Press the Fit to Page button. When the bar moves to the center and then the top, press the WPS button on the access point within two minutes. Wait for the unit either connect or show an error.

If your router is not set for WPA or WPA2 security protocol or the WPS button doesn't work, then you need to use a computer to redo the installation. First, install the setup software for the Pixma MG3250. If you do not have the install disk, it's available here: https://www.canon.co.uk/support/consumer_products/products/fax__multifunctionals/inkjet/pixma_mg_series/pixma_mg3250.aspx?type=software&language=&os=WINDOWS%2010%20(64-bit) . Begin the installation and click on the button for Wireless Connection. Walk through the steps and press and hold the Maintenance button when you see the Connect to the Network screen. Press Next when the LED shows the bar at the bottom. Press Next again. Choose the Wireless Setup Using the USB Cable. Go through all of the steps and connect the USB cable when prompted to do so. Press Next and wait for the printer to be detected. After the printer is detected, confirm the Access Point that is shown. (Note: for the Mac OS, there are a few extra steps.) Unplug the USB cable when prompted to do so.

I hope this helps.

It seems something wrong with your print head. Go check maybe something blocking it's way.

Here is the section of the Canon PIXMA manual that will help you best in how to do this. Essentially, you use the Tone button to switch modes.

yep that would be right
with a new hard drive , the bios will not boot up unless there is an installed operating system which a new hard drive will not have
What you may have to do is to get to the bios screen change the boot up to external or cd set and save that
connect the external cd / usb stick with the program installed then start up the computer as normal . it will boot from that system
