Hi printerguy1
There is not a way to totally turn off sleep mode. You can set various sleep mode time values. Click HERE for this information. I will submit your request for future firmware updates regarding turning off the sleep mode. Firmware updates when available are posted to Canon's website at www.usa.canon.com.
Regarding the other questions you described, It is recommended that you contact one of Canon's Technical Support Representatives directly to assist with these issues. To contact a Technical Support Representative, please use the link below:
