Solving Problems
Sending faxes without entering an access code in an environment in which a PBX is
installed.
Solutions
If your phone system requires an external access code to get an outside line, register the access code to the
printer, and enter # (hash) at the beginning of a fax number when sending.
The recipient's fax number is wrong.
Solutions
Check that the recipient's number registered in your contacts list or that you entered directly using the
keypad is correct. Or, check with the recipient that the fax number is correct.
The data being sent is too large.
Solutions
You can send faxes at a smaller data size using one of the following methods.
❏ When you send the fax in monochrome, enable Direct Send in Fax > Fax Settings > Fax Send
Settings.
"Sending Many Pages of a Monochrome Document (Direct Send)" on page 232
❏ Using the connected phone
"Sending Faxes Dialing from the External Phone Device" on page 230
❏ Using On Hook
"Sending Faxes Manually After Confirming the Recipient's Status" on page 229
❏ Separating the originals
The available memory in the printer is not enough.
Solutions
You cannot send faxes when the printer's memory is insufficient because of a lot of received documents in
inbox or confidential boxes or many unprocessed fax documents stored in the printer. Delete the
unnecessary documents in inbox or confidential boxes or process the unprocessed documents to increase
available memory.
The recipient's fax machine is not ready to receive faxes.
Solutions
Ask the recipient if the recipient's fax machine is ready to receive a fax.
Sending a fax accidently using the subaddress feature.
Solutions
Check if you accidentally sent a fax using the subaddress feature. If you select a recipient with a
subaddress from the contact list, the fax may be sent using the subaddress feature.
The recipient's fax machine is not capable of receiving faxes using the subaddress feature.
Solutions
When sending faxes using the subaddress feature, ask the recipient if their fax machine is capable of
receiving faxes using the subaddress feature.
