I have a MP C 4504 that has recently lost its mind. The church it's in had us move machine to allow painters to work behind it. Machine was powered down and moved to middle of room and then powered on. At this point my adventure began. Machine took considerably longer than normal to come ready. No code was given. When machine was ready, print jobs would come out 2 pages at a time. (10 page document would come out in 5 sets of 2 pages). If a door were opened, the screen would display the red outlined box with a flickering image of machine compressed into 1/4" line of pixels. I have formatted HDD, updated firmware, cleaned and re-seated RAM and connectors on main board, control board and user interface. Now when a door is opened, machine stops, but gives no indication on display that anything is wrong. The copier communicates readily with computers on network and scanning is no issue. Thanks in advance for any suggestions.

Re: Ricoh MP C 4504
stupid question but did you ck the new outlet for ground and proper voltage.
I can see a church cutting corners by paying a hobbyist to wire an outlet.
If you move it back to original location anything different?
is it on a good surge protector? -
Re: Ricoh MP C 4504
The machine stayed plugged to same receptacle and surge protector. Tried without protector, no joy.Comment

Re: Ricoh MP C 4504
+1 on this.
I had an issue with a Sharp "Locking Up" where the customer would have to reboot the device, so after troubleshooting we thought the main controller was shot. Swapped it for a different Sharp copier as a loaner, and within 2 days it started doing the exact same thing!!
Brought a line tester, and the AC voltage would fluctuate to as high as 120 VAC, but would drop down as low as 113 VAC. Also saw a 6-8% drop in current under a 15 amp load, and 5% under 20 amp.
Surge protectors are great to help protect against spikes...but they don't do diddly-squat for "Sags".
Good luck.Comment

Re: Ricoh MP C 4504
You moved the machine to allow painters to work...has the church had any other work done during this time? In particular, was any electrical work done? I am going along with the previously suggested "bad outlet" theory here."Enjoy every sandwich."

Re: Ricoh MP C 4504
The MFP must be haunted.
May i suggest doing a backup of the NVRAM, then do a clear, test if the problem is still there. Another suggestion if you have a spare SOP, try swapping them.Aye! Cut the crapComment

Re: Ricoh MP C 4504
Tried the NVRAM back-up, restore remedy. No change. Swapped controller board. No good. Looking at BCU now. Thoughts?Comment

Re: Ricoh MP C 4504
ok..I ve never had to test the voltage between neutral and ground and especially with a load on...
I guess that can left to the newbies to do when they are focused on texting with their phone at the same time as testing....
That will wake them up..
I Still remember the time i have a bad high voltage power pack and went to ck it and got hit wth 6,000 volts..
Low amperage but it left a big impression...Comment
