Send to a different fax machine
The problem might be related to fax machine settings or supplies status.
Try sending the fax to a different fax machine. If the fax quality is better, the problem is related to the initial
recipient's fax machine settings or supplies status.
Check the sender's fax machine
Try the following to check the sender's fax machine.
Ask the sender to try sending from a different fax machine. If the fax quality is better, the problem is with the
sender's fax machine. If a different fax machine is unavailable, ask the sender to consider making the following
changes:
● Make sure the original document is on white (not colored) paper.
● Increase the fax resolution, quality level, or contrast settings.
● If possible, send the fax from a computer software program.
