Turn main power switch off then on.If error reoccurs.call service.Functional problems. What does mean.

Error SC 998 on a Ricoh MP2851 printer indicates a functional problem with the printer. This error can be caused by a variety of issues, including hardware or software problems, or problems with the printer's firmware.
To troubleshoot this issue, try the following steps:

1. Restart the printer: Turn the main power switch off and then on again to see if the error message clears.
2. Check for any visible issues: Inspect the printer and its components for any visible issues that may be causing the problem. This can include debris or foreign objects that may have gotten stuck in the printer, or damage to the printer or its components.
3. Check the printer's firmware: Make sure the printer's firmware is up to date and that it is functioning properly. If the firmware is not up to date or is not functioning properly, it can cause the printer to display an error message.
4. Check the printer's connections: Make sure the printer is properly connected to any devices or computers it is being used with, and that the connections are secure. If the printer is not properly connected or the connections are loose, it can cause the printer to display an error message.

If you have tried these troubleshooting steps and the problem persists, it may be necessary to have the printer serviced by a professional. A technician will be able to diagnose the problem and determine the necessary repairs.
I hope this information is helpful. If you have any further questions or need additional assistance, please don't hesitate to ask.

An error is detected while operating the HDD and u have to replace

Find a local servicing dealer and ask what the error code means...

If they don't know or won't tell you, go somewhere else, even if that means the factory,

When you find someone who does know what it means and is happy to tell you, ask how much it will cost to fix...

Hello Mist. I have Functional problem detected. Turn main power switch off then on. If error appears again, please call service. SC672.Alficio MP 5001......?

After turn the main switch off and on the error appears again????
This error means that there is a bad comunication between the controller board and the operation panel.
Did you intervew in the machine? Some tecnical intervewing?

Your question is somewhat confusing as to the model. There is no Nashua SC550 as that seems to be the service code you have an issue with. There is a model 1013F but there is no SC550 code for that machine. That being said I will tell you what an SC550 code means on most all Ricoh, Gestetner,Nashuatec machines. The SC550 means your fuser oil/cleaning web life is over. The solution for this is to replace the web and then reset the counter which requires entry into the service mode. Both of these are going to require a service technician to complete.
Good Luck and Thank You for using Fixya.

SC542: Fusing temperature warming-up error The fusing temperature does not reach the fusing standby temperature within 135 sec (35CPM machines) or 145 seconds (45CPM machines) after the main power switch is turned on. - Possible causes - • Fusing thermistor defective or out of position • Fusing lamp open • Fusing thermofuse open • BICU defective • Power supply board defective • Poor fusing unit connection
Sometimes by going into service mode and then turn off copier and back on will clear this message or while in service mode do an error clear. But most of the time it is the thermistors in the fixing unit needs to be cleaned or replaced. I would probably call in the techs.

dear sir; the error code 320 on ricoh af 2027 it's means laser polygon motor problem, the laser unit right under the toner unit, litlle bit left. some error code can be reset why don't give them a try
