This isn't actually "my" problem, but I have a friend in the business who has trouble with several (3) Sharp AR-168S machines. Evidently they double image on the 1st copy only. If he runs say 10 copies, the 1st one comes out with the double/residual imaging, and the 2nd through tenth come out fine. He has tried replacing the drum, and it didn't make a difference. The problem still existed. If anyone has seen this problem and has a solution, I would greatly appreciate any advice. Thanks.

Re: Double image on the first copy only
Well, double images are most commonly caused by the drum - but I see you already replaced that. They could also be caused by the fuser or charger. Has he tried cleaning the charger. Instructions for that are on page 89 of the manual - which you can view here:
Assuming that doesn't work (which it probably won't, but always try the easy fixes first), he probably needs a new fuser, or possibly a new charger roller.
You should be able to tell which by measuring the distance between the first image and the double image, and comparing it to the circumference of each roller. Whichever one matches is the culprit.

Cause-A toner cartridge of a different destination is installed. EEPROM trouble Check the destination setup. Toner cartridge CRUM PWB trouble MCU PWB trouble CRUM connector disconnection
Check and remedy- Install a specified toner cartridge. Check the SIM 26-6 setup. Replace the EEPROM. Replace the toner cartridge. Replace the MCU PWB. Check connection of the CRUM connector. Execute SIM 16.
H4 indicates a heating problem in the fuser. The roller never reached a specific temp. Make sure the fuser is free of any left over paper pieces (maybe from a paper jam). Check to make sure its clean.

I am not 100% sure, but when you bought the copier how many "Rights" did you buy or recieve when the copier was installed? Most like you only got "Rights" for one user only and you may have to buy another legal or registered copy of the scanning software. Have you tried to have your "IT person" try to go on your network to give you the "Rights" to use the scanner?
