5.3 REMOTE DIAGNOSTICS AND CONTROL

This feature is available only on the Msys5600/5700 if a special ROM (Read Only Memory) is equipped with your fax machine.

Remote diagnostics and control is a feature that allows you to manage the end user's machine located in a remote location. You can diagnose the remote machine and control its system data without visiting the customer. If your machine displays REMOTE DIAGNOSTICS ? when you enter Function and 9, you can confirm that your machine has the special ROM installed.

Remote diagnostics and control consists of the following three items:

• GETTING INFORMATION ABOUT A REMOTE FACSIMILE

prints out the hardware and software information of the remote machine

• SETTING REMOTE OPTIONS

changes the system data of the remote machine

• RESETTING LEASE PAGE COUNT

resets the page count of the remote machine to 0. This item is for managing a leased machine.

To enter Remote Diagnostics:

1. Get into the Tech Mode by

pressing Function, #, 1, 9, 3, 4.

2. while in Tech Mode, press

Function and then the 9 key.

3. Press Yes.

4. Press No until you get to the

remote diagnostic mode you

5.4 TROUBLESHOOTING GUIDE

5.4.1 TELEPHONE SCREENING

FLOW CHART FOR FIELD REMEDY

INQUIRY FROM USER

When receiving an inquiry from the user, first ask the nature of the problem in detail. This is because most problem inquires are the result of:

1) Simple misoperation.

- Document are loaded upside down.

- The recording paper is not loaded properly.

2) A failure with the telephone line.

3) A failure with the other party's machine

In the case of 1), the user can solve the problem through the instructions given from the fax machine (help list printed out from fax machine).

In the case of 2) or 3), the user can check his/her own machine by performing a communication test with another (known good) facsimile machine.

INDICATION OF ERROR

During this preliminary screening procedure, the user can clarify the facsimile trouble by referring to the prompts on the LCD display. If the user is unable to provide this information of his own accord, proceed to "Recommended Flow For Telephone screening."
