T7100 don't start up. Error codes: 79:04 and 0xbabeface

Hi everyone,

 

We have a T7100 running on original supplies, that 3 weeks ago showed that message on startup:

We managed somehow to temporary unlock this fault and keep printing (opening/closing paper bay, etc) for a few more days.

 

 

That was until yesterday, when it showed these long messages on startup:

Now its impossible to startup the printer as it shows this message. On some startups, it don't shows it but plays a series of "beep" sounds, like 8 or so and screen keeps empty.

 

We tried:

-Updating firmware (update unsuccessful)

-Cleaned printheads

-Disconnected from power supply for 1 night

-Removed/reinserted ink cartridges

 

 

What could be causing this error, and how could we fix it? Thanks

Try a usb firmware update. If that does not solve the issue see the attached.

 

USB firmware update
If it is not possible to perform a firmware update using the Embedded Web Server (for instance, if the
printer has a System Error and the Embedded Web Server is inaccessible), it is still possible to do it
using a USB flash drive.
1. Turn off the printer.
2. Ensure that your USB flash drive contains a valid FMW firmware file and no other files.
3. Connect the USB flash drive to the USB host port on the Formatter.
4. Turn on the printer and follow the instructions on the front panel.

Thanks for that davidzuts

 

We have succcesfully updated the firmware using your method. However, the error message keeps showing on screen.

 

 

I've checked attached file, and our current status is "OFF-ON-OFF-ON-ON-ON-ON". This is almost exact to last line, except that our front panel (screen) is working for us.

 

We forgot to say that just before error code is displayed, the printer automatically loads and cuts a 10cm piece of paper. Don't know if this gives some clue.
