Ricoh CL 7000

[tankumus]

I have a CL7000 with an SC195. I just replaced the transfer cleaning unit blade and the transfer belt. I reset the maint. counters for these two items and upon a reboot I get the SC195. Also when entering Service mode, all my buttons are blank, no text. Any ideas or help would be appreciated!!! TIA

The code says it's a wrong serial number saved in the NV Ram.


Caused by:

corrupted NV Ram data
NV Ram is broken

Suggestions:

Open Front Cover - > Check 5-811-002 (Serial Number)
You may can re-enter the Serial Number inside the Factory Mode

CL 7000 SC195

I have checked the serial number, it is entered correctly. I ran a few test prints before I reset the maint. counters and all seemed fine. How would I get to "Factory" mode to re-enter serial number? Can't do it through SP mode. Also, does anyone know where I can download the firmware updates for this machine? I can use SP5-856-2 to upgrade the firmware through the parallel port. Can't seem to find the firmware file anywhere though. Any Ideas??? TIA

You don't know where to get the firmware?

Dude, I don't understand why peolple are maintaining Machines in the field without the basic, brand-related knowledge and necessary service ressources.

SORRY! If I offended you Jan! I was just looking for a little help. We are a small company and probably don't have the resources you do, but we do have the technical savvy! And manners!

[E Winter]

kind of confused, not really offended^^

I'm working in a small company, too but we won't mess around on stuff we can't guarantee a proper support. Stuff like firmware, manuals, technical- and modificationbulletings became much more importand over the years.

Eureka!!! The problem was the small 8-legged IC in the center of the BCU board. Replaced with a known working unit and problem solved! Still looking for the firmware though. Any help would be greatly appreciated! TIA

And Jan, I don't know of any service shop that has every resource, manual, or piece of software at their disposal. Maybe you could remember that before you degrade someone just asking for a little help. I thought that is what these forums were about!

AGREE, Jan, just remember not all of us have the backround support, but all of us Tecs do our best to try and keep things running.
As I know, no one forced you to answer the thread, and who knows maybe tomorrow it could be you or me in need of help, so just keep calm...

I am...

Well, beside telling my opinion regarding some things I also gave him the information he needed to localise the problem down to the NV Ram so I don't see a problem at all.

Jan,
You didn't give me any information that didn't already have. I have the service manual! It seemed you were talking about a different mode other than SP mode. And just for the record, the problem was NOT NVRAM, it was an IC on the BCU.

[E Winter]

What kind of IC? Ususally the socketed IC's are NV-Rams. In case of doubt you can check the IC inscribtion and ask google what kind of IC that is.

According to the SM the engine NVRam is located on the BCU.

This machine uses an 8 pin DIP on the BCU to store some of the sp settings - not really NV-Ram like we're used to with a battery, but flash ram - Learned that when annother tech did a memory ALL clear on a Lanier 2138 (I think that is the 3800 model) without the copy module - had to swap that chip and some other things to a demo machine with the copy kit and have a genuine japanese speaking Ricoh engineer walk me through reprogramming it.

BTW all firmware info is available on the Ricoh support site http://www.tscweb.net - you'll need a ricoh tech ID to register, but its free and if you've ever been to a Ricoh training class you should be able to get an ID - this site is a must for anybody working on Ricoh equipment no matter how small your shop is - can't tell you how many times it's saved me.

Now fight nice children...

Those primitive NV Rams can be found in several machines - not really uncommon. Those with the lithium battery are used inside the most "youngtimer" while Ricoh starts using very custumized SMD NV Rams for the current generation.

A memory all clear is a good idea though. I'd try this before replacing anything but write down the non default SP data first.

[Shadow1]

An All clear would be a really bad idea - unless they changed the firmware it will clear the serial number and the language selection - you will end up with a SC195 and when you get that cleared, you get a screen with all the graphics on it, but no text. Like I said, I had to get an engineer on the phone to completely recover the machine. An Engine clear is safe.

All the scanners use this type of memory (IS450, IS760, etc) Problem is that it is only good for a few hundred thousand write cycles, and the scanner writes the page count after every scan. I have a customer with 7 scanners all over 10 Million - read the counter, make 1 scan, read it again and its totally different. Ricoh knows about this (after they gave me a REALLY hard time about "accurate" meter readings on my calls and I had to write them nearly a master's thesis explaining why it wasn't working) so now almost everything uses "BCRam"
