Information Codes for the HP FAX-700 and FAX-750
The HP FAX-700 and FAX-750 display messages in the message window and information codes (info codes) in the
32-transaction report to warn of errors or problems with the machine or its operation. The information messages that
appear in the message window are described in the HP FAX 700/750 User’s Guide.
Table 5-1 lists the information codes for the HP FAX-700 and FAX-750 and suggests actions for info codes appearing
on the 32-transaction report.
Transmission Problems – In most cases, the action recommended when information codes appear during transmis-
sion (Tx Mode) is to “Resend fax.” If the customer has already attempted to resend the fax and failed, have the custom-
er send a fax to a known-good fax machine at the service center. If this operation fails, have the customer hook his fax
machine to another line and try to send the fax again. This action eliminates the customer’s line as the source of the
problem, and the customer’s machine is probably defective.
Reception Problems – In most cases, the action recommended when information codes appear during reception (Rx
Mode) is to “Retry operation.” If the customer has already contacted the sending party and had them resend the fax,
have the customer perform the following steps to isolate the problem to his fax machine:
1. Have the sending party attempt to send the fax to another party. If this fails then the sending party’s fax ma-
chine or line is probably at fault.
2. Have the customer move his fax machine to another line and attempt reception again. If this fails, the line is
probably not at fault.
3. Have another party attempt to send to the customer’s machine. If this also fails, the customer’s machine is
probably defective.
Procedures for listing and changing function parameters and a table of the service parameters follows the information
codes. If the customer cannot fix the problem, and the HP Customer Support Center cannot fix the problem using
remote diagnostics, have the customer return the unit for repair.
