Hi, this morning when when I turned on the printer the following message appeared on the display:

Error: 99.39.73

eMMC Read Only

and it's no possibly to use the printer.

How can I solve it?

Thank you.

Kind regards,

Samuele.

Hi Samuele,

1) Open the formatter cover and then reseat the eMMC PCA.

2) Then go to the pre-boot menu and do a format disk.

3) Download the latest firmware in a usb thumbdrive (formatted in FAT32) in its root directory.

4) Then in the pre-boot menu, download/install the firmware from the usb thumbdrive

5) Let the printer boot by selecting continue

I hope this may help,

Cheers!

If the first post does not solve the problem then likely you will need to replace the emmc card.
