1. This info might be a little bit too late for you, but in case other people seeking help... .. .
2. Turn off the printer, pull mains cable and after 15 seconds pull out Formatter board.
3. Heat up soldering iron, pore soldering flux on six SRAM memories (IDT71V256) and resolder them (no additional tin rquired). Work on Antistatic surface - ground yourself while touching the board!
4. After finishing with solder, wait until board cools down and clean flux with PCB cleaner (or pure Ethanol)
5. Check for solder shorts using good magnifying glass. Go back to point 3. and resolder any problematic pins (shorted).
6. Reasemble everything and power on.
NOTE: It took me about five inutes to resolder these and worked out right away. I cannot guarantee anyone can do it (depends on skills). Also "The Warranty" in case you have it :-) will be void with this inaction :-))))
