You need to do a factory reset (all) or try a memory clear of print data (partial).
Some one would have to walk you through it over the phone, or send it in to be done.should only be done by a service person.I cant post my email on here so not sure how to get in touch with you.

    go here and follow it to enter maintenance mode
    then enter 91 and then 99 to exit see if that fixes it.
    If not then go back into maintenance mode and enter 01 (this will clear everything) then 99 to exit

SOURCE: New Ink Cartridge

Is the toner cartridge an original Brother or is it remanufactured? The toner cartridge for this model is the TN-350, which has a "flag gear" on the left (gear) side. It is a little plastic piece that sticks out on the new cartridges and, after putting the cartridge in for the first time, it rotates out of the way. This is how the printer knows that the cartridge is new. Some remanufacturers either don't put the flag gear in or they forget to turn it back to the original position when they build the cartridge. So that would be the first thing I would look at.

I have an old cannon fax machine from 1988. It has been blinking "recieved in mailbox" and I can't figure out how to clear it. the model is canon fax-705. can anyone help?

It has messages or faxes in memory, and is waiting for the right conditions to print.
You may need to add paper, replace the toner cartridge, or clear a paper jam so that the printer can work.

It sounds like you have some bad jobs stuck inside the fax's memory. First print out a memory reference report. It will show you any bad jobs stuck in the system. Delete the memory reference jobs. Then go into set up and you want to turn off the option to store failed transmisions.

The system should store jobs while it is waiting for paper. If you have a lot of stored jobs and the memory is full it will not receive any more jobs until it can print out what is stored - so it would be normal for it not to recieve new jobs until all of the old jobs are printed.

All of a sudden, faxes stop coming out and the window says something to the effect...''Place US Paper in Upper Tray''. If I turn the machine on and off, the display clears and faxes that are in memory...

The fax machine is trying to print fax recieved copies on the bypass feeder.
Check up the setup menu on the control console.
Fine fax recieve.
You should find a selection for fax recieved in which paper tray.
Check this area, any that have the bypass feeder, de-select it.
Make selections for 8 1/2 x 11 paper in tray one.

ERROR 1200

The error 1200 refers to a problem with one or both of your cartridges, and as the printer uses these cartridges to print, it will not be able to print any recieved faxes. To avoid lost data, it blocks all fax usage as a result of recieving this message.
