Hi there you will need to replace the development motor but first try the following.


Entering the Service Mode
There are two ways to enter the service mode.
Method 1: Turn the machine on while pressing the “On Line” key and “Escape” key
together until the above message in the illustration appears on the display.
NOTE: If you switch the machine off, any jobs stored on the hard disk using the
sample print and protected print features will be deleted.
Check first with the user tools to see if there are any jobs stored with these
features
(Menu key - Sample Print, or Protected Print).
Method 2: Press the “Up/Down arrow” keys together for about 5 seconds, then
press the “Enter” key.
The above message shown in the illustration appears on the display.
NOTE: The machine automatically goes off line when you enter the service mode.

Using the up down arrows select Engine and enter by pressing enter or # key.

Using the up down arrows select mode 5 then enter using enter or # key then select 810 (SC reset) press enter then if you want to select 809 (SC Detection ON/OFF) Enter and select 1 to disable. Escape or return key all the way out and exit. Turn the machine off then on again and test if the same problem then replace the Dev unit if still having the problem then replacement of the motor likely. I can email you the complete service manual if you like.

Thanks J

1) First thing is check power source. If you have the printer plugged into a UPS (uninterruptilbe power source) unplug it and plug it directly into the wall. If it is plugged into the wall you might want to try a different outlet to see if it solves the problem.
2) Remove and reinstall the fuser. It may not have seated properly.
#) Make sure you installed the correct fuser. Should be RM1-1082. There should be a sticker on the fuser with this number. See the following article for more info. http://www.partsnow.com/service_today/0705.asp

If you still have the old fuser check also that it is a RM1-1082. If not you may have a euro version machine which would require a different fuser.

If the fusers match up you should check the voltage coming to the fuser if possible. If there is 100- 127 volts where the fuser plugs in you probably got a bad fuser or it was damaged in transit. If there is low voltage or no voltage you may have a board problem. Probably DC controller or Power Supply.

Run SP7-804-9
If you don't know how, or what that is, then you'd better call a service depot.
I will not post or discuss service mode procedures with end users, because you can create a great deal of problems if you're unsure what you are doing. (No offence)
