"Error state" isn't one single problem, it's a status message, and it can come from two different places. On a Windows computer, it usually shows up next to your printer's name in the print queue or under Settings > Printers & Scanners, and it means Windows can't currently talk to the printer. On the printer itself, Konica Minolta's bizhub line of office printers and copiers uses its own on-screen trouble codes, shown right on the control panel, for problems the machine has detected internally.
Both are fixable, and most of the time it doesn't take a service call. The trick is figuring out which one you're actually dealing with, since the fix is different for each.
Causes
On the Windows or Mac side
- The print spooler service has stalled or a stuck job is jamming the queue
- The installed Konica Minolta driver is outdated, corrupted, or doesn't match your printer's exact model
- The printer has dropped off the network, or its IP address changed after a router reboot
- Windows is trying to print with settings (paper size, tray, finishing options) that don't match what's actually loaded on the machine
On the printer itself
- A cover, front door, or the imaging or fusing unit isn't fully seated
- A paper tray is empty, or loaded with a size that doesn't match the print job
- A toner or waste toner sensor is dirty or misreading, even when the cartridge itself is fine
- A paper jam hasn't been fully cleared (bizhub machines flag these as J-codes)
- The machine has caught a hardware fault and locked itself down as a safety measure (a C-code, more on this below)
Solutions
Quick checks at the printer before you touch a computer
Before touching any settings, open and firmly close every cover and the front door, confirm the imaging and fusing units are pushed in all the way, and check that the loaded paper size matches what your document is asking for. On color bizhub models, reseat each toner cartridge, since a cartridge that looks installed can still be sitting slightly off its sensor. This alone clears a surprising share of "error state" messages without any software involved.
Fix it on Windows 10 or 11
- Press Windows key + R, type
services.msc, and press Enter. - Find Print Spooler in the list, right-click it, and select Restart. If it won't restart, choose Stop, wait a few seconds, then Start it again.
- If the same job keeps getting stuck, open File Explorer and go to
C:\Windows\System32\spool\PRINTERS, then delete everything inside that folder (this only clears the stuck job, not your printer setup). - Open Settings > Bluetooth & devices > Printers & scanners, select your Konica Minolta printer, and open its queue. Under printer properties, check the Advanced tab to confirm the correct Konica Minolta driver for your exact model is installed.
- If the driver looks outdated or mismatched, remove the printer, then reinstall it using the driver package for your specific bizhub model from Konica Minolta's official support site, or let Windows Update pull the current one.
- Print a test page. If the queue still says "Error," restart the printer itself, not just the print job.
Fix it on macOS
- Open the Apple menu > System Settings > Printers & Scanners.
- Select your Konica Minolta printer, click the - button to remove it, then quit and reopen the Printers & Scanners pane.
- Click + to add it back. macOS will usually re-detect the correct Konica Minolta driver automatically over the network; if it doesn't, install the driver from Konica Minolta's support site first, then add the printer again.
- Print a test page to confirm the queue clears.
Clear a trouble code on the control panel
If the error is showing on the printer's own screen rather than your computer, most bizhub models support a Trouble Reset:
- Turn the printer's main power switch off.
- Press and hold the Utility/Counter key, then turn the main power switch back on while still holding it.
- Keep holding until Trouble Reset appears on the screen, then release and tap it.
- Confirm you see OK on the display.
- Power the machine off again, wait about 10 seconds, then turn it back on and check whether the error is gone.
The exact button placement varies slightly by bizhub model, so check your model's manual if the key isn't where you expect it.
When It's Not a Quick Fix
Not every error clears with a reset, and that's worth knowing before you spend an hour on it. Konica Minolta's bizhub printers use a letter-plus-number system for their error codes: a code starting with J points to a paper jam location, while a code starting with C is a service call code, meaning the machine detected a hardware fault (a fusing, motor, or sensor issue, for example) and deliberately locked itself to avoid further damage. A Trouble Reset can sometimes clear a C-code temporarily, but if it keeps coming back, that's the machine telling you it needs a technician, not another reset.
