Using LAN Fax to send a fax

1. The device sends the fax job to the HP DSS server along with the fax number, and, if

authentication is used, the authenticated user’s credentials.

2. HP DSS splits the information into two files and sends them. The .HPF file contains information

such as the fax number, the number of retries, and other information that has been configured

on the Fax tab in HP DSS. Along with the .HPF file, the Task Manager sends a .TIFF or .PCL

image file containing the fax content. HP DSS copies the two files to a shared fax folder that is

configured on the LAN fax server and in the HP MFP DSS Configuration Utility.

NOTE For most LAN fax vendors, the administrator sets up a single folder named

"HPFSCAN" on the LAN fax server. All LAN fax vendors provide an administrative setting

that specifies the path to this shared folder. On the Fax tab of the HP MFP DSS

Configuration Utility, the user specifies a folder path, which is the path to this same

HPFSCAN folder.

3. The LAN fax server converts the .TIFF image(s) into fax format (analog), dials the number(s)

that are included in the .HPF file, and transmits the fax to the receiving fax device. If the

transmission is successful and the receiving fax device indicates success in the T30

communication with the LAN fax server; OR if the LAN fax server exceeds the server’s retry limit

(configured in HP DSS) AND the LAN fax server supports HP’s method for fax notification, the

LAN fax server writes a notification file to the shared fax folder for each fax number dialed.

4. HP DSS periodically checks the shared fax folder for notification files. If it finds a file, HP DSS

pulls it from the shared fax folder.

5. Using the information that is stored in the HP DSS log, the HP DSS server sends the

authenticated user an e-mail notification (5a) or prints a notification report at the MFP from

which the fax was sent (5b).
