ALL the Front-Panel LEDs are Lit but Nothing Else Happens
   

The BootROM DIMM is NOT correctly installed or is the wrong type.

1. Power OFF the Printer from the back and disconnect the Power Cord. Reseat the BootROM DIMM (looking from the rear of the Printer, the first slot from the left See Memory and BootROM DIMM's) making sure that it is installed correctly.

2. If the problem persists replace the BootROM DIMM (See Memory and BootROM DIMM's).
