MP301 SC901

[ponto700]

Hi,

last year i supply one MP301 and after 2 months machine came back with sc901 code... i check all and error was something with mechanical counter and machine dont have. i change power supply , etc and i found the problem as bicu board. after change machine works again. then i supply to some client other mp301 and after 2 weeks the new machine came back with sc901 error. again bicu is the problem. before i sold i pm all machine, test and all was ok.
what can be the reason to have this problems? the firs one was plugged direct without any protection and the second one he bough a surge protector.

thanks in advance.

That's odd - did you messed around with the NV Ram data/electronic counter? Is anything connected to the key counter connector?

no!! no one change nothing on NVRAM and there is no mechanical counter on the machine. the cable is there but no counter. until now all mp301 that i bought and others that i service no mechanical counter also.

I haven't noticed a mechanical counter in this series, too and I can't recall having this problem so far and we probably have (or had) >200 units in the field. Do you know the history of these "2nd hand" units?

I can also imagine that there might be a (factory) SP that could enable an electrical counter (probably not ducumented in the service manual sou you have to skip through the menu and check it) because the peer to peer diagram shows a connector. CN123 Pin1+2 (description says N.C. = not connected I guess). You can also try and connect a counter from a parts donator test wise/just for fun @CN123 Pin1+2 ^^

i also sold lots of this machines and only those 2 had problems... some client, same office... maybe can be a spikes in the electrical line no? becouse its not normal this special when i have more machines in diferent clients and diferent places.

Yeah that's unlikely indeed if this happens at different customers and really hard to guess what's going on

The MP 301 may not have a mechanical counter but it does have an SP option for using specially configured SD cards as key counters. Check SP 5987 Mechanical counter. It should be 0.

You have some one playing around with SP settings. Could be a competitor trying to make you look bad.

1 - try with sp 5987 mechanical counter 0>0ff 1>on

2 - try sp 801-002

3 - reload the firmware "system/copy"

Re: MP301 SC901

1 of the Most common faults for the BCU board to go in this machine is electrical power surges and lightning strikes. These can happen at any time, night or day.

Those basic surge plugs and adapters will not protect against those problems.

I would recommend
1) Try what the other technicians have suggested. Make the changes to the settings in the SP mode. If that doesn't work
2) Try installing a mechanical counter from an old machine like a 1515 or 161. Those do fit in the MP301 (I've tried and tested it)
3) if you still experiencing problems you will need to replace the BCU board and get some proper electrical protection on the machine. Something like an Automatic Voltage Regulator will help. Also be sure to check the electrical wiring supply of the building. I had a problem recently where the clients wiring in the building was damaging the equipment. Once electrician sorted that out things started running much better.
4) Don't forget to undated your firmware.

All the best friend.

I had a client with a Lanier 1200 word processor located in a portable office building at China Lake Naval Weapons Center. It kept destroying the data on floppy disks. Checked the power with a Dranetz Power monitor that the region support person brought up from LA and were getting multiple hits a minute. Made a list of the things that they need to have done. They got Naval engineering out the next day to install a proper grounding rod and no more problems.

Brilliant example there Slimslob.

I wish I could do calls at China Lake, no telling what you'd see there.

Unless you had the proper security clearance, you wouldn't see anything.
