NOTE: Retrieved stored faxes can be accessed by entering the Fax Printing menu and changing to
the Print all received faxes mode.
If the Print all received faxes mode is selected, then all incoming faxes will be printed. Any faxes that
are currently stored in memory will also be printed.
If the Use Fax Printing Schedule mode is selected, then faxes will be only printed per the fax printing
schedule. The fax printing schedule can be set to lockout an entire day (24 hours) or lockout a time
period during the day. Only one lockout period can be set, but it can be applied to any number of
days. The lockout period is setup under the Fax Printing Schedule menu.
Adding only one type of event into the schedule would make the product behave as Store All
Received Faxes or Print All Received Faxes based on the type of single event added i.e. Single
Store Event would cause device to Store All Received Faxes and Single Print Event would cause
Print All Received Faxes.
NOTE: When the lockout time ends, any faxes that were received and stored during the lockout
period are printed automatically.
Use fax over VoIP networks
VoIP technology converts the analog phone signal into digital bits. These are then assembled into
packets which travel on the Internet. The packets are converted and transmitted back to analog signals
at or near the destination.
The transmission of the information on the Internet is done digitally instead of analog. Therefore, there
are different constraints on the fax transmission that may require different fax settings than the analog
Public Switched Telephone Network (PSTN). Fax is very dependent upon timing and signal quality, so a
fax transmission is more sensitive to a VoIP environment.
The following are suggested changes in settings for the HP LaserJet Analog Fax Accessory
500 when it is connected to a VoIP service:
●
Start off with the fax set in V.34 (Fast) mode and with Error Correction Mode (ECM) turned on.
The V.34 protocol handles any changes in transmission speed needed to accommodate VoIP
networks.
●
If numerous errors or retries occur with the unit set to V.34, set V.34 Off and set speed to Medium
(14,400 bps).
●
If errors and retries persist, set a lower fax speed as some VoIP systems cannot handle the higher
signal rates associated with fax. Set the Maximum Baud Rate to 9,600 bps (Slow).
●
In rare cases, if errors persist, turn off ECM on the product. The image quality might decrease.
Ensure that the image quality is acceptable with ECM off before using this setting.
●
If the preceding setting changes have not improved the VoIP fax reliability, contact your VoIP
provider for help.
