How to Fix Konica Minolta bizhub 4700P Firmware Error 900.43 When Printing PDFs
Question details
The user experiences a firmware error that crashes the printer when trying to print specific PDF documents.
- Product
- Adobe Acrobat DC
- Device & OS
- macOS
- Scenario
- Sending specific or complex PDF files from Adobe Acrobat DC on a Mac to a Konica Minolta bizhub 4700P printer.
- Observed behavior
- The printer triggers Firmware Error 900.43, crashes immediately, and requires a full manual reboot to restore functionality.
Before proceeding with troubleshooting, ensure your Konica Minolta printer is connected to your Mac network and that you have saved any open work, as the printer will require a physical reboot to clear the crash state.
Use the 'Print as Image' Workaround in Adobe Acrobat
Using this setting forces the software to rasterize the PDF into an image before sending it to the printer, bypassing the firmware's internal rendering engine that causes the crash.
This method serves as a highly effective temporary workaround. Because the printer receives a simple flat image instead of complex PostScript or PCL data, the firmware is not overwhelmed.
Launch Adobe Acrobat DC and open the PDF file that is causing the error. Click on 'File' in the top menu bar and select 'Print', or press Command + P on your keyboard.
In the Print dialog box, locate and click the 'Advanced' button near the top right of the window.
Check the box labeled 'Print As Image'. You can leave the resolution settings at their default. Click 'OK' to save this setting.
Click the 'Print' button to send the document to your Konica Minolta bizhub 4700P. The document should now print without triggering the firmware crash.
Update Printer Drivers and Firmware
Firmware Error 900.43 is a known issue related to PostScript and PCL rendering. Updating the printer's software provides a permanent resolution.
Bypass Printer Crashes with WPS Office
Since Adobe Acrobat DC's specific print rendering triggers this Konica Minolta firmware crash, switching to WPS Office to view and print your PDFs can bypass the rendering error entirely without requiring complex firmware updates.
- 1. Install WPS Office: Download and install the free WPS Office application for your Mac from the official website.
- 2. Open the PDF: Right-click the problematic PDF file, hover over 'Open With', and select WPS Office.
- 3. Initiate Printing: Click the 'Print' icon on the top toolbar or press Command + P to open the print dialog.
- 4. Select Printer: Choose the Konica Minolta bizhub 4700P from the printer dropdown list and configure your copies and page range.
- 5. Print Successfully: Click 'Print' to safely send the job to the printer using WPS Office's stable print rendering process.
Frequently Asked Questions
What causes Firmware Error 900.43 on Konica Minolta printers?
Error 900.43 is generally caused by a failure in the printer's internal PostScript or PCL rendering engine. When applications like Adobe Acrobat send complex vector graphics, unparsed fonts, or specific code structures, the firmware fails to interpret them, resulting in a complete system crash.
Does 'Print as Image' reduce the print quality of my PDF?
Yes, slightly. Printing as an image rasterizes the vector document into pixels. While it effectively prevents printer crashes, you might notice a minor reduction in the sharpness of very small text or fine line art compared to standard vector printing.
How do I check my current Konica Minolta printer firmware version?
You can check the firmware version by printing a Configuration Page directly from the bizhub 4700P's physical control panel, or by typing the printer's IP address into a web browser to access the PageScope Web Connection interface.
Will this error happen if I print from my iPhone or iPad?
Usually, no. This specific error is tied to the macOS or Windows print drivers interacting with Adobe Acrobat. Mobile printing via Apple AirPrint utilizes a different rendering pathway that generally avoids triggering Error 900.43.
