Minolta Code 9903 | Konica

The Konica Minolta error code 9903 (often appearing as "99-03") is a generic "trouble" or "internal error" code typically associated with a software or document processing malfunction rather than a specific hardware part failure. This error generally occurs when the machine's controller cannot process the data it has received, often due to complex file formats or driver mismatches. Common Causes of Error 9903

Complex Print Jobs: Large or highly complex files—particularly Microsoft Excel documents with multiple worksheets or variable data—can trigger 99-series codes.

Driver Conflicts: Using an incorrect or outdated printer driver is a frequent cause of processing errors.

Firmware Outdated: Older firmware versions may lack the necessary protocols to handle modern document data, leading to internal timing or processing failures.

Network Timing Issues: In some cases, the error is treated as a "99 jam," which can be caused by sensor timing issues during the pre-phase or startup. Step-by-Step Troubleshooting Guide 1. Perform a Soft Reset

Before attempting technical fixes, restart the hardware to clear temporary memory buffers.

Turn off the main power switch (usually located behind the front door or on the side). Unplug the power cable and wait for at least 60 seconds. Plug the machine back in and restart. 2. Verify and Update Drivers

Ensure you are using the official Konica Minolta driver specifically designed for your model.

Visit the official Konica Minolta Download Center to find the latest version.

If you are using a "Universal" driver, try switching to a model-specific PCL or PostScript driver. 3. Clear Internal Malfunction Settings (Service Mode) konica minolta code 9903

If the error persists on the display, you may need to reset the malfunction status through the service menu. Warning: This should ideally be performed by a technician.

Access the Service Mode (usually by pressing Counter > Display Keypad > Stop > 0 > 0 > Stop > 0 > 1). Select System 1. Navigate to Initialization and select Trouble Reset. Follow the prompts to restart the machine. 4. Check Firmware Version

Konica Minolta often releases firmware patches to address specific 99-series errors. Ensure your machine is running at least version G00-RF or newer, as these versions contain stability fixes for data processing. 5. Analyze the Source Document

If the error only occurs with specific files, try the following:

Print as Image: In the PDF or document print settings, select "Print as Image" to bypass complex vector processing.

Simplify Excel Files: If printing from Excel, try printing one worksheet at a time or saving the file as a PDF before printing. When to Call a Technician

If these steps do not resolve the issue, the problem may lie with the Image Stabilization process or the IDC sensors (1 and 2). A certified technician can check the "level history" of these sensors or adjust the transport speed and registration loop to fix permanent timing errors.

For further assistance, you can find local support through the Konica Minolta Service Locator.

Does this error occur consistently on every print job, or only when you try to print specific types of files? The Konica Minolta error code 9903 (often appearing

The Konica Minolta "Code 9903" typically appears on older color production devices (like the bizhub C550, C650, C451, C5500 series, and some LD models). It is not a standard "toner empty" or "paper jam" code—it points to a specific hardware or calibration failure.

Here are the main features / characteristics of Error Code 9903:

Pro Tip for IT Teams

Treat Code 9903 as a canary in the coal mine – it often appears when the HDD is nearing capacity or has bad sectors. If Code 9903 recurs after clearing, run HDD Check (Service Mode → State Confirmation → Memory/HDD Adjustment) to avoid data corruption.

Step 2: Enter Service Mode

Warning: Changing service mode settings incorrectly can affect machine performance. Proceed carefully.

  1. Press the Utility/Counter key on the control panel.
  2. Press Details (or Stop → 0 → 0 → Stop → 0 → 1 on some models—check your manual).
  3. Touch Service Mode and enter the password (usually 927292729272 or 12345678).

Final Verdict

Konica Minolta Code 9903 is a serious signal that your printer’s video pipeline is failing. While a simple reboot works in 10% of cases, the majority require hardware intervention—most often faulty memory on the video board or outdated/corrupted firmware.

For IT managers: Document the error frequency. If C-9903 appears more than once per month after reseating cables and updating firmware, proactively replace the video board or retire the device. For home office users: Unless you are technically skilled, call a Konica Minolta certified technician. Attempting board-level repairs without ESD protection can permanently destroy the $1,200+ MFP board.

Remember: The "C" in C-9903 means Critical. Treat it accordingly.

The Konica Minolta 9903 error (often appearing as ) is a common "phantom" jam or timing error found on bizhub series machines like the C258, C308, and newer "i" series models. The Problem: Timing & Sensors Step 2: Enter Service Mode Warning: Changing service

Unlike specific hardware failures (like a motor or fuser), a is generally a timing-related paper jam error

. It occurs when the machine's logic expects a sheet to reach a sensor at a precise millisecond, but it arrives too early, too late, or the sensor fails to reset. Top Causes Dirty Sensors:

Dust (especially paper lint) on the registration or transport sensors can cause the machine to "think" a page is stuck when it isn't. Firmware Glitches:

Older firmware versions are notorious for these codes during startup or when processing complex files (like large Excel sheets). Media Settings:

Using heavy cardstock or glossy paper while the machine is set to "Plain Paper" causes a speed mismatch that triggers the timing alarm. Quick Fixes & Troubleshooting The "Power Cycle":

Turn off the main power switch (not just the sub-power on the panel), wait 30 seconds, and restart. Clean the Sensors:

Open the right-side door and use a can of compressed air or a soft cloth to clean the sensors along the paper path, specifically the Registration Sensor Check Paper Quality:

Ensure the paper is dry and the guides in the tray are snug. Curled or damp paper often causes the slight delays that trigger 9903. Clear System Error: If the code is "stuck," you may need to enter Service Mode

(Counter -> Display Keypad -> Stop 0 0 -> Stop 0 1) and perform a Trouble Reset KONICA MINOLTA Business Solutions Australia Final Verdict

The 9903 error is frustrating because it often leaves no physical paper to remove. If it happens once, a restart usually fixes it. However, if it recurs frequently, it’s a sign that your machine needs a firmware update from a technician or a deep cleaning of the paper feed rollers Service Mode steps for your particular bizhub model to reset this code?
