E004 Fixing unit failure E100 Scanner unit failure E246 The Counter board is left out E676 Communication error E677/6F-61 ROM check error E677/6F-63 RAM error E733 A fault occurred in the communication between the SCNT board and ECU board/TOP signal cannot be detected New E805 Fan failure
TRY THIS: E004 Fixing unit failure Cause: (1) Shorted/broken wired main thermistor (2) Shorted/broken wired sub thermistor (3) Broken wired heater/blown thermal fuse Solutions: (1) Turn the power off and remove the fixing unit from the machine. Measure the resistance between the fixing unit connector J301-1 (FSRTH) and J301-2 (GND). If the resistance is not within the range between 350 W and 520 W (room temperature of 20°C), replace the fixing film unit. (2) Turn the power off and remove the fixing unit from the machine. Measure the resistance between the fixing unit connector J302-1 (FSRTH2) and J302-2 (GND). If the resistance is not within the range between 360 W and 530 W (room temperature of 20°C), replace the fixing film unit. (3) With the fixing film unit removed, if there is no continuity between the fixing unit connectors J303-1 (ACN) and J303-3 (ACH), replace the fixing film unit. (4) Replace the EPU board. (5) Replace the ECU board.
On this machine the fuse would be on the power supply internally. Of course I take it you've checked the plug fuse first? You may have some glass quick blow fuses that you will be able to see but such models tend to respond to such things by serious power supply failure. Good luck
Press the [Menu] button on the Control Panel until 'Reports' is displayed on the top line of the Display Screen.
Press the [Left] or [Right] arrow button until one of the following reports is displayed, and then press the [Enter] button to print the report.
Report / List
Description
Phonebook List
This list shows all of the numbers currently stored in the machine's memory as Speed Dial and Group Dial numbers. NOTE: This list can also be printed by pressing the Phonebook button on the Control Panel.
Sent Fax Report
This report shows information on recently sent faxes.
System Data List
This list shows the status of the user-selectable options. This list can be printed to confirm any modifications to settings that have been modified.
Scheduled Job Information
This list shows the documents currently stored for Delayed faxes. The list shows the starting time of the Delayed fax.
Message Confirmation
This report shows the fax number, the number of pages, the elapsed time of the job, the communication mode, and the communication results. You can set up your machine to automatically print the message confirmation report after each fax job.
Junk Fax Number List
This list shows up to 10 fax numbers specified as the junk fax numbers by using the Junk Fax Setup menu. When the Junk Fax Barrier feature is turned on, incoming faxes from those numbers will be blocked. This feature recognizes the last 6 digits of the fax number set as a remote fax machine’s ID.
Multi-communication Report
This report is automatically printed after sending documents from more than one location.
Power Failure Report
This report is automatically printed when power is restored after a power failure, if any data loss occurs due to the power failure.
What is it telling you is that it was unpluged or lost power for a short period of time.
First of all just try pressing the Stop Button.
The try powering it off with the power switch. Remove the power cord for a minute then replace the plug and turn on. That should clear it.
Anoying message, but just an indication that you lost power unexpectedly.
This is from the FAQ on a similar model (the 770). My guess is that it won't be much help, but who knows... :
The machine is not receiving a power signal. Make sure the power cord is plugged securely to the power outlet.
If a surge protector or an extension cord is being used, disconnect them and plug the fax machine's power cord directly to the power outlet. If the fax machine is still not receiving a power signal, try plugging the machine's power cord into a different outlet on another circuit breaker.
Good luck
