Hi all. I have a problem with this machine. It works really slow if i copy one page after another. After the machine is in ready mode, after i press the start button, it scans the original ,and then main motor starts rotating and it does this for about 30 sec. And after all this, the paper is drawn into the copier. After this first copy, if i try to make another one, it does the same thing. if i press 5 and then start button ( to make 5 copier), it works well, except for that same first copy. I cleaned the machine and rebuild the fuser, but i have not changed any parts. The copier has about 7k copies. Any ideas?
