HI, I have an MSL5000 that I have just replaced the SDLT drive with a LTO. The new drive will not initialise, and I beleive that you require a "maintenance code" in order to tell the loader mech that it now has an LTO instead of SDLT. I purchased this unit second user and do not have the manuals, and cannot find this "magic code" anywhere. Does any one a) have the manual and could forward the code to me, or b)know where I can find the service manual.
