The alarm light keeps flashing, cannot receive any fax

I think the NCU Modem board 160K72460 is bad.

That is responsible for sending and receiving faxes.

That suggests a sensor is jammed or damaged... sorry I know no more.

The alarm light is flashing and the screen indicates read maintenance chapter in the user's guide.

red light means there is an error. check all covers. open all cover and close again

Printhaed!!

Fax display screen always reads, "Auto receive". When attempting to fax, the busy light flashes. Busy light stops flashing for 30 seconds, then starts flashing again.
Above is the default settings for the fax.

NGB0 indicates signal error or line condition error.
U need to check the phone line. U can hook any single line phone to the phone line, check for tones without background noise.

Got an answer from Canon NZ:

1. Press the red Stop/Reset button and keep it pressed.
2. The 'Alarm' light will flash - count 12 flashes.
3. The screen on the Canon will show 'SERVICE MODE' and something #1.
4. Press the right arrow key twice to bring up FAX TYPE #3.
5. Press OK to check the country - mine showed Australia when it should have been New Zealand. Scrolling with the arrow keys shows the countries available for your machine.

make sure the paper stack are seated properly and the cover is properly closed

how to connect fax

The alarm sounds for only 5 seconds.When you receive a fax and the paper jams, the fax will be received into memory. When it has finished receiving the fax, the alarm will sound momentarily. When you remove the jammed paper, the fax will print automatically.
