ricoh 1060 nv ram replacing??

[fshead]

hi
i have a ricoh 1060 that wouldnt see the print/scan chip on it..
followed a "tip" that reseating the nv ram might work..
it didnt, but in the process i bent a pin that latter fell off..
i have a parts unit 1060 wth 3.5 mill copies, and swapped the board wth the nvram.
this machine has 160k but now comes up wth 3.5mil.
can i upload from another machine wth 160k or is a house of horrors?
the print/scan problem turned out to be a dirty connection which i cleaned wth alcohol and air

When you replace the NVRAM you should ALWAYS backup all machine settings! The NVRAM holds all current engine settings. The 160k machine now has all settings of the 3.5M machine.
The only thing you could you is order a new NVRAM, reseat it on the 160k board, do a 300k maintenance, and perform all necessary adjustments.
And hopefully the machine will work again.

You can not (officially) reset or alter the total counter on an engine board. Although some say that it is possible, you could run into serious trouble. When you want to know what happens when you try to reset the total counter, read this :

i did reset total counter af1045, but SC 350 comes frequently

Good Luck!

its a general rule if you want to reset or replace nvram make a back up. and upon doing such try to isolate the problem first. doing the bending of pins to reset usually do if you want to reset the counter which is far from a print/scan copy quality problem, well i suggest to replace a new nvram and hope you have a factory settings sheet of that machine, if you cant explain to the customer why the counter goes 3.5M. if you can and the machine giving no sign of any problem. just let it...

good luck.

the machine works well in limited"shop" enviroment..
i have the original sheet or at least a recent smc report.
i never adj the laser and dont know if could be an issue down the road.
i did replace the dev,drum is lik new as are the feed rollers.
as for bent pins i worked on this late night wth low light conditions..if i knew the pins were so light id never even pull it.

OK, yes do a backup to a card of the NV-RAM settings. Also a print of all user settings, and full SMC (SP 5-990-1). Then restore onto the new NV-RAM. You could probably back up and restore using an eeprom reader / writer, which I did have to do on an old analog Ricoh one time when replacing the NV-RAM.

ABOUT PULLING;

1) wear and anti-static wrist strap
2) take a very thin tweaker flat screwdriver and alternately pry in a twisting motion under each end of the NV-RAM
3) move up to a bigger tweaker, using the same motion, gently
4) use a tweezer type IC puller to grab it and pull straight out

Step 4 is optional if you are good with the small flat scredrivers, but I have a cheap one that works well - loosen the chip before using it though!

Some don't know this, but you can brain wash an NV-RAM sometimes by;
1) powering off the machine
2) installing it backwards
3) powering on for a few seconds
4) powering off
5) installing it correctly

Now, upload, or manually enter all settings from your SP print 5-990.

Hi
thnx for the reply
i have the anti static wrist band from my laptop repairs,
and know to only do this with plenty of light and not rushed.
Do i redo dev setup 2801?

Well it's a bit tricky but it may be possible to solder the broken pin back in place. Or maybe this isn't even necessary because this is one of the "not used" pins - have you tried to run it after the pin fell off?

Yeah a work mate of minde did that by accident and was kindly surprised what happened with the total counter

Well - a prommer was a nice investment back then. Unfortunately the NVRams on newer machines have a much different design and can't be edited that easily.

If you have an NV-RAM backup on your PCMCIA card, then no. If you have an SMC print out of the values before switching out the NV-RAM, no. If not, and the developer is almost NEW, maybe yes, maybe no, it is a risk with used developer, check toner density first (before 2-801). Otherwise, change the developer, and run 2-801. You know you MUST leave the front door open, turn on the machine, wait for the open door message on the screen, go into SP mode, close the door, wait for warmup, then finally run 2-801 with NEW developer. Otherwise process control is run on boot up and your NEW developer concentration is altered before the TD sensor is initialized to the NEW developer.
