Ricoh Error SC899 — What It Means & How to Fix It
By Ryan Green · Updated August 2026 · Independent guide · PrinterCare USA LLC (not affiliated with any printer manufacturer)
The SC899 error on your Ricoh printer indicates a software-level communication breakdown between your computer and the printer's processing unit. This typically happens when print data gets corrupted in transit, usually due to outdated drivers, a full print queue, or temporary firmware glitches. The good news is that most users resolve this within fifteen minutes using basic troubleshooting steps.
Unlike mechanical errors, SC899 doesn't mean your printer hardware is failing. Instead, your Ricoh device is rejecting malformed data because it cannot interpret the job correctly. This is actually the printer protecting itself from processing incomplete or corrupted instructions that could cause bigger problems.
How to fix it — step by step
- Clear the Print Queue on Windows. Open Settings, navigate to Devices, then select Printers and Scanners. Find your Ricoh printer in the list, click it, and select Open Queue. Right-click each pending job and delete it, or click Printer in the menu bar and select Cancel All Documents. If the queue appears frozen, restart the Print Spooler service by pressing Windows Key plus R, typing services.msc, finding Print Spooler, right-clicking it, and selecting Restart.
- Clear the Print Queue on macOS. Open System Settings, go to General, then select Printers and Scanners. Find your Ricoh printer and click it, then click Open Print Queue. Select any jobs listed and click the X button to delete them. If the queue still shows jobs, open Terminal and type sudo cancel -a to force clear all pending jobs system-wide.
- Power Cycle Your Ricoh Printer. Turn off the printer using its main power button and wait a full thirty seconds before turning it back on. This clears temporary memory and resets communication protocols. Allow the printer to complete its full startup cycle, which typically takes one to two minutes, before attempting to print again.
- Remove and Reinstall Printer Drivers. Go to Settings on Windows or System Settings on macOS and select Printers and Scanners. Right-click your Ricoh printer and choose Remove Device or click the minus button. Visit the official Ricoh support website, enter your exact printer model number, download the latest driver package for your operating system, and run the installer. Restart your computer after installation completes.
- Check and Update Printer Firmware. Access your Ricoh printer's web interface by finding its IP address in the Network Settings menu on the printer's touchscreen display. Open a web browser on your computer and type the IP address into the address bar. Log in with your credentials, navigate to System Settings or Administration, and check for available firmware updates. Download and install any available updates, allowing the printer to restart automatically when the process finishes.
- Test with a Simple Print Job. Open Notepad on Windows or TextEdit on macOS and type a single line of text. Print this basic document to your Ricoh printer to isolate whether the SC899 error appears with simple jobs or only with complex documents. If simple prints work, the problem may be related to specific file types or print drivers used by your primary applications.
- Verify USB Connection and Replace Cable if Necessary. If your Ricoh connects via USB, power off both the computer and printer, then disconnect the cable completely. Inspect the cable for visible damage, bent pins, or debris. Reconnect the cable firmly to both devices, ensuring it clicks into place, and power everything back on. If you suspect cable damage, try a different USB cable or switch to network printing if your printer model supports it.
- Contact Ricoh Support or Schedule Remote Assistance. If SC899 persists after completing all previous steps, the printer may have a corrupted firmware module requiring factory reset or advanced diagnostics. Contact Ricoh technical support or schedule a remote support session starting at forty-nine dollars, where a technician can access your printer's diagnostic logs and perform advanced troubleshooting you cannot do alone.

Frequently asked questions
Does SC899 mean my Ricoh printer is broken?
No, SC899 is a software communication error, not a hardware failure. Your printer is actually functioning correctly by rejecting corrupted data. Most users resolve this error within minutes by clearing the print queue and restarting their printer and computer.
Why does SC899 happen with only certain documents or applications?
Some applications may use printer drivers or settings that create incompatible data packets your Ricoh cannot process. Try printing the same document from a different application like Notepad or Adobe Reader. If the error disappears, the problem lies with your original application's print driver settings rather than the printer itself.
Will a factory reset on my Ricoh printer erase saved settings?
Yes, a full factory reset returns your Ricoh to original settings and erases stored configurations, network settings, and job logs. Only perform a factory reset if Ricoh support explicitly recommends it. Most SC899 issues resolve without factory reset, so try all other troubleshooting steps first.
Should I use a USB connection or network printing if SC899 keeps happening?
If SC899 occurs consistently over USB, switch to network printing via Ethernet or WiFi to bypass USB communication issues. Network printing often proves more stable for resolving driver-related errors. Update your network printer drivers separately after adding it as a network device.
