Memory Full Error Occurs
❏ If the printer has been set to save received faxes in the inbox, delete faxes you have already read from the inbox.
❏ If the printer has been set to save received faxes on a computer, turn on the computer that is set to save the
faxes. Once the faxes are saved in the computer, they are deleted from the printer's memory.
❏ Even though the memory is full, you can send a monochrome fax by using the Direct Send feature. Or you can
also send a fax by dialing from the external phone device.
❏ If the printer cannot print a received fax due to a printer error, such as a paper jam, the memory full error may
occur. Clear the printer problem, and then contact the sender and ask them to send the fax again.
