How to Fix Ricoh Printer Error SC 899-00 – Causes and Solutions

This guide is for informational purposes only. We are not affiliated with Ricoh or any brand mentioned.

SC 899-00 is one of those Ricoh errors that can genuinely baffle people, because the machine stops completely and nothing on the panel tells you what sent it over the edge. One moment the printer is running normally; the next it’s locked up with SC 899-00 and won’t respond to anything.

What’s actually happening is that the Ricoh’s web/image controller — the processing unit that interprets incoming print data and turns it into something the engine can print — encountered a job it couldn’t handle and crashed. The error is the controller’s way of saying it got data it couldn’t make sense of. The good news is that this is almost always a software or data problem, not a hardware failure. This guide covers every confirmed cause and the fixes that have actually worked, ordered from the easiest to the most involved.

If you’re also running into driver installation issues on Windows, our guide on Ricoh printer driver not installing on Windows 11 covers that separately.

What SC 899-00 Actually Means on a Ricoh

Ricoh’s service codes are structured. The first digit tells you which part of the machine is involved: 1xx is the scanning system, 2xx is the laser/exposure unit, 5xx is the fuser, and so on. The 8xx range covers the controller, firmware, and software layer — everything that handles data processing rather than physical printing.

SC 899 specifically falls under what Ricoh’s documentation calls a “web/image controller error.” The subcode 00 indicates a general controller crash, as opposed to a more specific fault within the controller subsystem. The machine’s internal processor received print data that it either couldn’t interpret, found to be corrupted, or ran out of resources trying to process — and rather than try to continue and produce a bad output, it shut down the controller and threw the SC code.

What Triggers SC 899-00 — The Confirmed Causes

This matters to understand before jumping into fixes, because different causes need different solutions.

• Printing from a web browser — this is the most commonly reported trigger. Web pages generate complex, often poorly formatted print data that the Ricoh controller can’t always process. Print-from-browser jobs regularly cause SC 899 on Ricoh MPC and MP series machines
• Corrupted PCL print data — specifically, a PCL driver sending scalable font data in a way the Ricoh’s PCL firmware can’t handle. When this happens, the font data corrupts the printer’s memory buffer and crashes the controller. This is a firmware-level incompatibility, not a one-off bad file
• Windows using an IPP or WSD port instead of LPR/RAW — Windows 10 and 11 updates have quietly switched many network printers to Microsoft’s IPP class driver or WSD ports. These send data in a format that older Ricoh firmware wasn’t designed to receive, and the controller crashes trying to parse it
• Firmware that’s behind on updates — particularly PCL firmware. Ricoh has released firmware updates specifically to address SC 899 on several MPC and MP series models. Running outdated PCL firmware makes the machine much more vulnerable to this error
• A complex or oversized PDF — documents with embedded fonts, high-resolution images, or unusual encoding can overwhelm the controller’s processing capacity, especially on older machines with less RAM allocated to the print controller
• A stuck job that the machine keeps trying to process — once a bad job crashes the controller and the machine restarts, that job often re-queues automatically. Unless it’s explicitly cleared, the machine will crash again on the next startup

How to Fix Ricoh SC 899-00 — Step by Step

Work through these in order. The first two steps together solve the majority of SC 899-00 cases without needing anything more involved.

Fix 1: Power Off Completely and Clear the Stuck Job

The most important first step is a full power-down — not standby, not the panel’s power button that puts the machine into sleep mode. The goal is to completely clear what the controller is holding in memory, so the bad job doesn’t immediately re-trigger the error the moment the machine comes back on.

1. Press and hold the main power switch until the machine powers off completely. Wait for the panel to go dark and all lights to stop.
2. On MPC series machines, there is often a secondary main power switch at the side or rear — turn that off too.
3. Wait at least 60 seconds. This isn’t just a restart — give the capacitors time to fully discharge.
4. Before powering back on, disconnect the network cable from the printer. This prevents any queued jobs from arriving before you’ve had a chance to clear them.
5. Power the machine back on and wait for it to reach the ready state.
6. From the control panel, go to Job Status (or Copier / Printer in the top menu), select Print Jobs, and cancel or delete any jobs still showing in the queue.
7. On the PC that sent the last print job, open Devices and Printers, right-click the Ricoh printer, open the print queue, and delete everything listed there.
8. Reconnect the network cable and test copying directly from the machine’s glass — if it copies clean, the machine itself is fine.

Fix 2: Enable Auto-Delete for Error Jobs

Once the immediate crisis is sorted, this setting prevents one bad job from locking the whole machine in the future. Without it, a corrupted job that causes SC 899 will simply re-queue after the machine restarts and trigger the same error all over again.

1. From the Ricoh’s control panel, go to User Tools / Counter.
2. Select System Settings.
3. Navigate to Printer Features (or Printer/Scanner Features depending on model).
4. Look for Auto Delete Temporary Print Jobs and set it to On.
5. Also check for a setting called Delete Temporary Print Job or Invalid Job — enable this as well if present.
6. Confirm and exit User Tools.

With this on, a job that causes a controller error will be automatically removed rather than held and retried. The machine recovers on its own instead of requiring manual intervention every time.

Fix 3: Change the Print Port from RAW/WSD to LPR

This fix addresses the Windows port issue that’s been confirmed to cause SC 899 on Ricoh machines. The RAW port sends data in a continuous stream without the handshaking that LPR provides, making it more likely that a job arrives in a state the controller can’t process. WSD ports have similar issues. LPR is more controlled and gives the printer a clear signal about job boundaries.

1. Open Control Panel > Devices and Printers (or Settings > Bluetooth & devices > Printers & scanners on Windows 11).
2. Right-click the Ricoh printer and select Printer properties.
3. Go to the Ports tab and click Add Port.
4. Select Standard TCP/IP Port and click New Port.
5. Enter the Ricoh printer’s IP address. When the wizard asks for the port type, select LPR (not RAW).
6. In the queue name field, type lp (lowercase).
7. Tick the box for LPR Byte Count Enabled.
8. Finish the wizard, then on the Ports tab, select the new LPR port as the active port for this printer.
9. Click Apply and OK.

The “LPR byte count” option is specifically worth enabling — it tells the printer exactly how large each job is before transmission begins, which prevents the controller from receiving a job mid-stream and getting confused by where it ends.

Fix 4: Enable “Spool Before Printing” in the Driver

This is a smaller tweak that, when combined with the LPR port change above, meaningfully reduces SC 899 occurrences. Spooling means Windows builds the entire print job on the PC before sending it to the printer — rather than streaming it live. The result is a cleaner, complete job that the Ricoh’s controller receives all at once rather than in pieces.

1. Open Devices and Printers, right-click the Ricoh printer, and select Printer properties.
2. Go to the Advanced tab.
3. Under the spool options, select Spool print documents so program finishes printing faster, and then choose Start printing after last page is spooled.
4. Click Apply and OK.

Fix 5: Update the Ricoh Firmware (System, Engine, and PCL)

This is the most important fix for machines where SC 899-00 keeps coming back even after the job queue is cleared and port settings are corrected. Outdated PCL firmware in particular is a documented cause — Ricoh has released PCL firmware updates across the MPC 3003, 3004, 5503, MP series, and Aficio range specifically to address controller crashes triggered by certain job types.

The firmware update must cover all three components: System firmware, Engine firmware, and PCL firmware. Updating only one of these leaves the incompatibility in place.

1. Print a configuration page from the Ricoh’s control panel to find the current firmware versions — go to Counter / User Tools > Inquiry or print from Machine Status > Print Reports.
2. Note the model number exactly, including any letter suffixes (e.g., MPC3004ex, MP C3003SP).
3. Visit Ricoh’s official support portal and search for your exact model.
4. Download the latest System, Engine, and PCL firmware files.
5. Use Ricoh’s firmware update tool (usually a Web Image Monitor upload, or a PC-connected utility) to apply each file in the sequence Ricoh specifies — typically System first, then Engine, then PCL.
6. After all three are installed, the printer will restart. Let it complete the full boot cycle before testing.
7. Print the configuration page again and confirm all three firmware versions have updated.

Fix 6: Change How Problem Files Are Printed

If SC 899-00 only occurs with specific documents rather than all print jobs, the file itself is the trigger rather than a configuration problem. Some document types — especially web pages printed directly, complex PDFs with embedded fonts, or large files with high-resolution images — can exceed what the Ricoh’s controller can process in one pass.

• Web pages: Instead of printing directly from the browser, use the browser’s “Save as PDF” option first, then print the PDF. This converts the web content into a format the Ricoh’s controller handles much more reliably.
• Complex PDFs: Try opening in Adobe Acrobat Reader and printing with Print as Image enabled (found in the Advanced print settings). This rasterises the PDF before sending it, removing the font embedding and complex instructions that crash the controller.
• Large files: Try reducing the print quality in the driver settings (e.g., 600 DPI instead of 1200 DPI) before sending. This reduces the data volume the controller needs to handle per page.
• PostScript-heavy files: If your Ricoh supports both PCL and PS drivers, try switching between them. Some document types that crash the PCL controller print without issue on the PS driver, or vice versa.

Fix 7: Access the Ricoh SP Mode to Clear the Error (Advanced)

If SC 899-00 won’t clear through normal power cycling and the printer stays locked in the error state, Ricoh’s SP (Service Program) mode can be used to clear the fault code and reset the controller. This is typically a technician-level step, but on SP-accessible machines it can be done without a full service call.

The standard SP mode fault clear on most Ricoh MPC and MP series machines:

1. With the printer powered on and showing the SC 899-00 screen, press Clear / Stop and hold for 3 seconds.
2. Enter the SP mode access sequence (on most models: press 107 on the numeric keypad, then hold Clear / Stop for 3 seconds until the SP mode screen appears).
3. Navigate to SP 5-810 (listed as SP 5810), then sub-code 02.
4. Press Execute.
5. Power the machine off using the main switch, wait 60 seconds, and power back on.

This resets the controller’s fault state without affecting stored data. If the SC 899-00 code immediately returns after this reset, the bad print job is re-queuing and the queue must be cleared before the machine can recover fully.

SC 899-00 on Specific Ricoh Models — What’s Different

The error behaves slightly differently across model families, and it’s worth knowing which quirks apply to your machine.

Ricoh MPC 3003, MPC 3004, MPC 5503: These models have a well-documented SC 899 history linked to PCL firmware. If yours throws SC 899 regularly, the PCL firmware update is the primary fix — service technicians who work on these frequently report that keeping PCL firmware current eliminates the problem on these machines almost entirely.

Ricoh MP 301, MP 2852, MP C320DN: On these models, SC 899 is more commonly triggered by web browser print jobs and Windows WSD ports. The LPR port switch and spool-before-printing setting tend to be the most effective fixes here.

Ricoh Aficio MP W2401: The wide-format Aficio W2401 has been reported to throw SC 899 when receiving jobs with certain scalable font packages. Firmware update is the confirmed resolution on this model.

When SC 899-00 Points to a Hardware Problem

In the majority of cases, SC 899-00 is a software and data issue, and the fixes above resolve it. But there are situations where the error keeps returning despite correct firmware, clean drivers, and cleared queues — and that’s when the controller board itself needs attention.

Signs that the hardware may be at fault rather than software:

• SC 899-00 appears immediately on startup, before any print job is sent
• The error returns every time, even after SP mode fault clearing and full power cycles
• The machine can’t complete a copy job from the glass (which doesn’t involve the print controller) — if copying also fails, a different hardware fault may be involved
• SC 899-00 started appearing after a power surge or interruption

If the error matches any of those patterns, the controller board or its associated components are the likely cause and a service engineer is the appropriate next step. A board-level fault won’t be resolved by any driver or firmware fix.

Preventive Habits That Reduce SC 899-00 Risk

• Never print directly from a web browser. Save to PDF first, then print. This one habit eliminates the most common trigger for SC 899 on Ricoh machines in office environments
• Keep all three firmware components updated. System, Engine, and PCL — all three together, not just one when a prompt appears. Set a reminder to check for Ricoh firmware releases quarterly
• Use LPR ports on all networked PCs. Set this up when installing the driver, so the problem doesn’t arise in the first place
• Check for Windows Update driver substitutions. After major Windows updates, it’s worth verifying that the correct Ricoh PCL6 or PS driver is still in use, rather than a Microsoft-substituted IPP class driver
• Route large or complex files through PDF first. For anything that involves embedded fonts, vector graphics, or unusual encoding, converting to PDF before printing reduces the chance of the Ricoh’s controller hitting data it can’t process

Frequently Asked Questions

What does Ricoh SC 899-00 mean?

SC 899-00 is a web/image controller error on Ricoh printers and multifunction devices. It means the machine’s print processing unit — the controller that interprets incoming print data — crashed while handling a job it couldn’t process. The 8xx series in Ricoh’s error code system covers the controller and software layer, and SC 899 specifically indicates a controller crash rather than a mechanical or hardware component failure. The most common triggers are corrupted print jobs, browser-originated print data, or PCL firmware incompatibility.

Can I fix SC 899-00 myself, or does it need a technician?

Most cases can be resolved without a service call. Clearing the stuck print job, switching to an LPR port, and updating the Ricoh firmware together address the majority of SC 899-00 occurrences. The SP mode fault clear is a slightly more advanced step but doesn’t require specialised tools — just the access code for your model. A technician becomes necessary when the error persists through all software fixes and returns on startup before any job is sent, which suggests a controller board fault rather than a data or configuration issue.

Why does SC 899-00 keep coming back on my Ricoh?

The most common reason it returns is that the bad print job is still sitting in the queue. After the machine restarts from an SC 899 error, it often picks up where it left off and immediately tries to process the same job again — which triggers the same crash. Clear the queue completely on both the machine and every PC that prints to it. If it continues after that, outdated PCL firmware is the next thing to address. A recurring SC 899 that doesn’t clear with firmware and queue fixes suggests a configuration issue with the print port (RAW or WSD rather than LPR) or, less commonly, a controller hardware problem.

Does SC 899-00 cause any data loss on the Ricoh?

Not on its own. SC 899-00 is a controller crash — it locks the machine until the error is cleared, but it doesn’t wipe the address book, user codes, stored documents, or account data. The risk to stored data only appears if you use the wrong SP mode option during recovery. Options that include “NV-RAM Clear” or “Clear All Memory” will erase stored settings — those should be avoided unless you specifically need them and have backed up the machine’s settings first.

Is SC 899-00 related to a paper jam or toner issue?

No. SC 899-00 is entirely separate from paper jams, toner, fusing, or scanning errors. It’s a software and data processing error at the controller level. If the machine also shows paper jam codes or toner alerts alongside SC 899, those are separate faults that should be addressed independently — clearing SC 899 won’t resolve them, and resolving them won’t clear SC 899.

Will resetting the Ricoh to factory defaults fix SC 899-00?

A full factory reset might clear it temporarily by wiping the stored job data, but it’s generally not the right approach. Factory reset also deletes your network configuration, address book, user codes, and all stored jobs — and if the underlying cause is outdated PCL firmware or a mis-configured print port, the error is likely to return after the machine is set up again. The targeted fixes — clearing the queue, updating firmware, switching to an LPR port — address the actual cause without the collateral damage of a full reset.
