Flashing ! A red light with the ! is flashing on our fax machine but no error messages are showing, does not seem to be printing. Any advice please? Thanks

Call Canon support 1-877-287-7032 ,you will get a live person who will get it running in 10 minutes, I hope

All the ink tanks should be red with no flashing.
The tanks that are flashing or have no red light on , need to be replaced.

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

There are actually some certain meaning on the red light and green light showing different information to user. The summaries are:
1) Green On, Red Off = Printer Ready.
2) Green Fast-Flashing, Red Fast-Flashing = Printer warm up.
3) Green Fast-Flashing, Red Off = Printer off-line.
4) Green Slow-Flashing, Red Off = Processing Data.
5) Green Off, Red On = Cover Opened, Toner Empty or Developer Unit / Drum unit missing.
6) Green Off, Red Fast-Flashing = Paper Jam or waiting for jam reset.
7) Green Off, Red Slow-Flashing = Paper Empty or Paper tray is not inserted.
8) Green Off, Red Off = Printer power is off.
9) Green Very-Slow-Flashing, Red Off = Printer in sleep mode.
10) Green (any condition above), Red Slow-Flashing = Toner low or paper empty.

So what is your printer condition? Better know what is going on your printer so can solve the problem.

when trying to copy or receive a fax machine will flash printer error and send out blank page i replaced the ink cartridge and blue air tho it but nothing seems to help

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.

Unplug power / plug back in.... NoGo? try this:

Function
7
press monitor key slowly 4 times
*
6 (RAM INITIALIZE)
scroll down to CLEAR FLASH MEMORY
set (wait for reboot)

If that doesn't work, scroll down to ALL JOB CLEAR and set.

Last resort....
scroll down to SHIPMENT SET
set
2 for no

Did the developer problem go away?

Red flashing light on '8BK' small black cartridge on left hand side.
If this indicates 'low ink' then it is not alerting me on the monitor. I think this is something different because my printing has been interrupted. Aileen

The error keeps flashing and the machine will not work. The error reads, "check cover/cart". We put the cartridge in and out about 10 times and the same error message keeps flashing. the fax machine is still not working. Help!
