Can not receive manually?
Is there a document set in the automatic document feeder (ADF)?
You can not receive with a document set in the automatic document feeder
(ADF). Remove the document and try again. (Q15-2)
Did you press START/SCAN before you hung up the handset?
When you hear a high pitched tone, press START/SCAN before you hang
up the handset. Review the procedure for manual receiving with the
optional handset kit installed on the fax. (Q7-7)
Are the documents you receive of poor quality?
Is your toner cartridge running low on toner?
Remove your toner cartridge and rotate it 5 or 6 times to evenly distribute
the remaining toner and try again. If this does not solve the problem, you
should change the toner cartridge. (Q15-14)
Is the other fax functioning properly?
The sending fax usually determines image quality. Try copying a document
on your own fax. If the copy is clean then the other fax has a problem. Call
the other party and ask them to clean the scanning glass on the other fax.
Can not receive a confidential document in your confidential
mailbox?
Does the other party's fax support subaddress/password transactions?
If the other party's fax does not support subaddress/password transactions,
you can not receive confidential documents.
Make sure the other party knows the correct subaddress/password for your
confidential mailbox.
Can not poll another fax and receive its document?
Are you polling without a subaddress/password?
If the other party's fax is a Canon fax and can set a polling ID, ask them to
set the polling ID for 255 decimal or 1111 1111 binary.
Are you polling with a subaddress or password?
Contact the other party and confirm that their fax supports receiving a
polling request with a subaddress or password.
If the other party's fax supports subaddress/password polling, confirm that
you are using the correct subaddress and password.
If the other party's fax does not support subaddress/password polling, call
the other party without subaddress/password. (Q11-3)
