Ok Ricoh MP 7502 comes up with 672-00 -01 -02 connection from controller to op panel on 5054s 672-11 bugs in chips bad hdd and crazy static shock that's normal on those boxes. MP 7502 sc 672-01 on screen when you disconnect hard drive and get it to rest sc870 sc860 sc819 address book problem normal fix hard drive. bad connection to panel. (usb) I did memory clear not all or engine. I reformatted hard drive (oem) updated firmware. I cleaned and even swapped dim/ram. swapped fuser bad rear connection or shorting thermistors. swapped and checked connection for paper Tsb from ricoh. it will work for days. goes into sleep mode will turn back on. turn off will come back on. when it sits for a long time in sleep mode, blue light glowing (energy save) hit the energy save button no response. open front doors or adf nothing. turn machine off and back on 672 comes back up. Sorry about the writing Thanks for any advive
