SC990 Ricoh PRO907

[tludden]

I was getting SC990 3 weeks ago and was told HDD, Ram, and Firmware. I replaced and upgraded all. After that I found to be haveing ADF issues Jamming not centered on glass ect. After a jam in ADF I again got SC990. I cleaned all sensors by blowing them out retested was fine for three weeks. I am now going back for SC990. I will look at history for ADF jams. Anyone have any other ideas???

Thanks

Not sure about your 907ex, but I just found a year old firmware for my MP6501 that was having ongoing 990 codes - there isn't a TSB nor is it listed in the firmware history, arrgggh. Found in Gooses Guide

If the HDDs have just been replaced, be sure to download the stamp data (SP5853).

With SP5990 004 (SMC Report – Logging Data), print the most recentinformation for SC990.

The SC990 information displays the file name, line number, and value. Reportthis information to your technical supervisor. For example:
Function.c LINE: 123 VAL:0









Have you try to replace the cable of add ?

Good luck
