You might need to upgrade the firmware

EIO is the port for the network card on the back of the machine turn off machine remove card from EIO2 and install into EIO1 turn machine on and see what happens. If this does not work then open the formatter casing and remove the memory chips (OF COURSE WHEN THE MACHINE IS OFF) after removingone turn machine on and see if it boots up.
The 49 error is normally a software issue with the machine and it has locked within the network area or the memory.
Hope this helps you and please rate me

To continue turn off then on
A critical firmware error has

This type of error can be caused
by invalid print commands,
corrupt data, or invalid operations.
In some instances, electrical
noise in the cable can corrupt

printer. Other causes include

connections, or specific
Sometimes, the formatter itself is
at fault, which is usually indicated

Hewlett Packard 49.XXXX Errors
I hope this will be of assistance to you, any repairs under taken are at the owners free will.
Hello, the dreaded 49.2F9D Error Turn Power On/Off and other related 49 Errors.
This tip relates to the Hewlett Packard P3005 Series Printer - General reference to most HP Laser Printers
There have been many reports of this error in the HP genre of laser printer. This is a generic fatal error; the root cause is undetermined in most cases. It could be related to an application "corrupt data" or faulty printer firmware, or the formatter board or other associated hardware or accessory. The first step in troubleshooting this error is to isolate the printer from any computer source - disconnect from any I/O ports, Network/USB etc... Power cycle the printer. Does the error still report? If NO then an application may be causing the error, try to isolate the file causing the problem. Clear any pending print jobs. If YES then Firmware/Formatter most are the problem. A new firmware file can be found here. P3005FIRMWARE
Pay close attention to PDF files with embedded JPEG files.
Pay close attention when printing Emails or Web Pages.
In rare circumstances the fuser has been reported to cause the 49.2F9D error. (P3005 specifically)
