Ricoh 3025 - replace photoconductor unit

[Tricky]

Hi all

I have a problem with a Ricoh 3025 its displaying a message "replace photoconductor unit"

Ive searched the forums and found this
http://www.copytechnet.com/forums/ri...coh-3232c.html
and i have cleared 7 804 : but I cannot find the PCU clear.
I have tried 5801 and all clear also 2804 'new pcu check' with no success. I have also tried 3 different drum units and this has not worked which makes me think theres a counter stored in the machine but which one?

Doing SP 2801 initializes the developer, clears the counter and removes the message.

Thanks mate that worked.

To keep the message from ever showing up again, try SP 5-912-001 and change the setting to 0. That kills the message permanently...

SP5-801-001?????????? to reset a drumcounter? You cleared the whole machine with this one. I hope you will not run into trouble in the future.

Precisely why end users shouldn't go into SP modes, they're trigger-happy laypeople who'll try anything to save money.

No offence Skynet, but you've been quite lucky with that one!

did you replace the pcu? If not you would most likely run into toner spilling and copy quality problems.

Cancelling PCU Counter

Be aware that turning off SP 5912-1 (PCU Counter) will eventually cause the machine to overtone - this will almost certainly become a major mess as toner will dump heavily - in a worse case scenario if the spilling is excessive toner will make its way down to the feed stations - this becomes a major problem with regard to feed problems. It would be advisable to leave SP 5912-2 turned on (1) and increase SP5912-2 from 60K to 90K - failure to replace the developer and drum at set intervals will create problems far greater than simply replacing the pcu compnents and developer. A rebuild of the PCU and developer change takes less than a half hour - being faced with a unit that has overtoned can require considerable time to clean.

Cleared what...? the copy quality didnt seem affected that much.

That's the all reset on the machine. Sets everything back to default. It might not give you a problem now, but it probably is wiser to not use this unless it's recommended by tech support. It can lead to consequences and repercussions in the future.

[Eric1968]

With SP5-801-001 you reset all the settings to default. This means that all engine settings are at default. In most cases this causes problems. This SP should be used with caution. The machine adjusts a lot of voltages and much other settings. Resetting all these settings to default can cause the machine to behave very strange.
Why not change the PCU-parts when the machine reports it in the display. You can clear the 'Replace PCU'-message, but you will certainly run into troubles in the coming weeks/months.
Performing maintenance every 60 to 120k extends the life of your machine and keeps customers happy.

Eric1968 -

I agree 100% with your last post to this thread - disabling the PCU counter is creating unecessary work later on - these units run relatively consistent if the drum and developer are changed every 60K to 90K. In the long run you are beter off taking the 30 minutes to vacuum the PCU assy. and replace the necessary part. I have come across many of these units that have had the PCU counters turned off - they go into a continous toner add condition and eventually the entire cavity is covered in toner.

@Caveman

Here (in Holland) we never turn off PCU-counters. Like you said, it takes about half an hour to replace the PCU-parts.

I've seen the effects of resetting the whole machine and it did not made me happy...

[rthonpm]

It's been both standard procedure with both Ricoh and the dealer I'm with now to turn the counter off unless the customer replaces their own PCU. Generally the rebuildable units die well before the 60,000 threshold anyway so we swap them out with a 1027 unit and then just let them go until copy quality goes down, or when any EM call comes in close to the next replacement threshold.
The main false add toner issues I've seen on these is when using the rebuildable unit or a bad toner hopper.
