I am unable to retrieve fax from memory, on the Fax Setup menu no reference to faxes in memory. I have a Lexmark 6650. When the fax wa sent it said "printing" but nothing came out

Usually, faxes are temporarily sent to the printer's memory when one of the cartridges' ink level is not substantial for printing. You are advised to replace the cartridge/s, *without navigating away from the message "fax sent to memory", by opening the printer cover and replacing the low-ink cartridge/s. After the new cartridge/s is installed, close the printer cover and press OK button to let printer print the fax stored in the memory.
* Make sure not to navigate away from the "fax sent to memory" message. You will lose the fax-in-memory data once you turn off the printer or navigate away from the message.

normally you will need to let the printer know that you have preformed any maintenance on it by clearing the error count after such an error occurs and is fixed it is normally listed under general or service options on the printer menu but you may need to look through the users manual

hope this helps

Problem faxing-error message

Error 388:

There is too much noise on the line for a valid connection between two fax machines to complete. The noise problem might go away over time.


Retry the fax reception at a different time when telephone line conditions have improved. Call the telephone provider if line conditions fail to improve.

Error 403:

During a V.34 transmission, the local machine is unable to connect (handshake) with the remote machine and is consequently unable to send a T30 frame. This occurs when the line is disconnected or if line conditions degrade during the session.

  • Remove any pass-through devices from the phone line, and then try the fax again.
  • Confirm that the fax/phone cable is no longer than required, and that it does not pass near unshielded electric motors such as fans, heaters, or household appliances.
  • Try to send the fax at a different time when telephone line conditions have improved.

Unable to clean message

When trying to use your Brother machine you get the message "Unable to _____". The blank may be the word Change, Print, Scan or Clean and these words may vary from model to model.
This message is a general message and will appear for different reasons. It often indicates a paper jam or a mechanical issue. Complete the following to determine the possible issue.

Check for foreign objects, such as a clip or ripped paper, inside the machine.
Open the scanner cover by pulling up on the lower right corner of the cover. Look inside the machine and remove any foreign objects. If you see jammed paper or another item inside this area, gently pull it out and then close the scanner cover securely.

2. If the error continues to appear, the machine may have a mechanical problem.
If the error message continues to appear, the machine will need to be reset. Resetting the machine will erase all faxes in memory and the Fax Journal Report. However, there is a way to transfer faxes in memory and the Fax Journal Report to another fax machine to print them out. Do the following to transfer the data and reset the machine...

Screen says CHANGE UNABLE 51.

Follow the instructions listed below:

Error Message Cause Action

The machine has a mechanical
A foreign objects such as a clip or
ripped paper is in the machine.

Open the scanner cover and remove any foreign
objects inside the machine. If the error message
continues, see Transferring your faxes or Fax
Journal report on page 90 before disconnecting
the machine so you will not lose any important
messages. Then, disconnect the machine from
the power for several minutes and then
reconnect it.

Try this and let me know if this helped solve the problem. Binary Bob

Brother MFC-5840CN unable to scan

From Brother Customer Service email:

You can try the following reset - it will most of the settings back to the default options.

Unplug power cord to the machine.
Press and hold down Menu.
Plug power cord back in.
Let go if menu when fax/scan/copy flash.

You may see either "maintenance" or "machine error xx" on the screen.

Type stop/exit, 9, 1.
The machine should show "param init" or similar to show that the reset is being done.

It will then go back to or machine error.

Type stop/exit, 9, 9.

This should take the machine out of maintenance mode and back to normal.

If the error is still present the machine will require an engineer to resolve the issue.

"Unable To Change" message. Tried all suggested fixes none work. Can you provide any additional help beyond the standard fixes. Nothing is jammed, turning it off for even days doesn't remove the error...

press menu then start bk copy then fourtimes arrow up. what error code does the machine display?

In case you have an error 50 you have to open the printer cover and to reinsert the encoder strip which is out of position into the ph. This occurs sometimes after a serious paper jam.

search error 50 for dcp 110, 115 or mfc 210 here. its the same procedure.
