External software (like print management tools) tries to connect using outdated credentials or incorrect ports.
Because code 9903 is often a software-timing issue, check your current firmware. Professional technicians recommend ensuring the device is on at least to resolve known stability bugs. 4. Check Consumables & Sensors
Here’s a detailed feature write-up on , suitable for a knowledge base article, IT support guide, or tech bulletin.
Konica Minolta’s is a critical system notification typically encountered on bizhub series multifunction printers (MFPs). Unlike common paper jam or toner low alerts, this code relates to job log management and data integrity. Recognizing and addressing it promptly ensures uninterrupted printing, scanning, and copying—while safeguarding audit trails.
Follow these troubleshooting steps in order, moving from the simplest soft-resets to more advanced technical interventions. 1. Perform a Full Power Cycle (Sub and Main Switches) konica minolta code 9903
Once fixed, take these precautions:
Manually runs stabilization to clear pre-phase startup locks. Print Driver / Firmware Upgrades system to address known data-processing errors. When to Call an Authorized Service Technician
Try to copy (not print) a multi-page document. If copying works but printing fails, the issue is with the print data or network driver. If copying also fails, proceed to Step 2.
If the error persists after a reboot, use the Trouble Reset function. Turn off the main power switch. Turn it back on while holding the key. Touch [Trouble Reset] on the screen. Ensure [OK] is displayed. Turn the machine off and on again after 10 seconds. 4. Clean the IDC Sensors External software (like print management tools) tries to
Go to Settings > Devices > Printers & Scanners , click your Konica Minolta device, open the print queue, right-click, and select Cancel All Documents .
For the IT professional, the code is a source of "ticket fatigue." It is rarely a quick fix. It
Enter the service menu and manually run an Image Stabilization . If it fails with a "P-code" (e.g., P-21), it indicates a specific hardware failure in the drums or IDC sensors.
Go into service mode and check for color registration errors. Unlike common paper jam or toner low alerts,
Preventing the 9903 error is about maintaining a clean, consistent print path.
Quickly press the following sequence immediately after power-up: (timing is critical).
(often displayed as 99-03 or labeled as a Controller JAM ) is a common infrastructure error that typically affects the bizhub i-Series (such as the C250i, C300i, and C360i) as well as several high-volume monochrome and color multi-function printers (MFPs) .
