This message show when temporary memory full fill because of too much pending command or execute command which hold printer temporary memory. So you need to clear or delete pending command from its memory then restart your computer. Thanks a lot

There are two possible reasons why your printer display the error message.

1. Poor Line Condition
- electrical interference on the line -Make sure electrical or electronic appliances do not interfere with the printer's phone line
- poor line connection - If you have a phone try connecting it directly to line outlet. Listen to the dial tone, if you hear noisy and static, then you will need to call your local telephone company cause there is a problem in your phone line. If dial tone is clear and stable then try checking the telephone line cord that you use to connect your printer from the line outlet, replace if broken.
- alarm system or another device on same line, these interferes with transmission / reception of the fax machine. Try connecting the printer all alone and then try sending a fax.

2. Memory Full
- There is no space to store incoming fax messages. Delete all stored fax messages.

That is a problem with your phone line. Get a line filter from Radio shack and install it between your wall socket and the fax. This should solve teh issue.

to solve this ... you need to have your phone company "condition" the line. Somewhere between you ant the CO (Central Office) there is/are come crummy (read Corroded) connections.

This may cost you ... inquire before you order the conditioning.

E-mail is more convenient ... consider instead of FAX

I had the same problem trying to send out faxes out using my Brother MFC 7340. I use a magic jack phone line. Page 106 of the user manual says if sending via VOIP phone line, you should press menu, then 2, 0, 1 to select "Basic (for VOIP) mode. Then press ok. Then press stop/exit. This cuts the modem speed down to 9600 bps and turns ECM off. Then retry to send the fax. I did that and can now send and receive faxes.

Plug a phone into the line and listen for static. Too many phones on the line, bad lines,etc, can cause a poor line condition. Try the unit directly into the phone line, no answer machine or anything else on the line. Maybe the memory thing is it has a lot of faxes that it hasn't been able to send.

not thing to do with your machine call your local phone comp they will take care of you!

Just because you can hear fine when you call the same number and talk to the person there, does not mean a fax machine won't sense noise on the line. A fax machine is much more sensitive, and cannot have a lot of noise or it will not be able to render the image at the other end correctly. So have your phone company and the recipient's phone company check the lines for problems.

There is also the chance that the two fax machines cannot get along. We have clients that we cannot use our fax machine for, because it always generates a similar error to yours. If we go to the other side of our building and use a separate fax machine on a different line, it goes through just fine.

The other half of the error is out of memory. If you have not tried these ideas, try them also: To gain extra memory, you can turn off Fax Storage, print fax messages in memory or cancel a Delayed Fax or Polling Job. In general, shutting the unit off will purge most everything out of memory.
