Minolta bizhub c280 color copy make blue or red lines

The problem you are experiencing with your Konica Minolta Bizhub C280 not accepting new print jobs after changing the K drum and developer, could be caused by several reasons:

1. The new K drum and developer might not be compatible with the printer, please check if the new parts are compatible with your specific printer model.
2. The print queue on the computer may be stuck or corrupted. You can try clearing the print queue by going to the control panel and searching for "printers" and then right-clicking on the Bizhub C280 and selecting "See what's printing" and then "Cancel all documents"
3. The firmware of the printer may need to be updated, you can check the Konica Minolta website for any firmware updates for your specific model.
4. The 500,000 page count that you mentioned, could be a "life counter" on the printer, some printers have a maximum page count before needing maintenance, so it might be related to the issue.
5. The issue may also be related to the print server. You can try resetting the print server or reconfiguring it, or you can try connecting the printer directly to the computer and see if that resolves the issue.
6. Sometimes, resetting the network settings on the printer can also fix the problem. You can try going to the printer's web interface and find the network settings, and reset them to factory defaults.

It is highly recommended to consult the user manual or the technical support of Konica Minolta for specific instructions on how to perform these troubleshooting steps and avoid causing any further damage.

Question edited for clarity.

If it is new, it is under warranty. Contact the maker or seller. It is likely to be a fault with the scanning tube or may be the optics / CCD. Is is via the document feeder or on the platen glass? Lift the lid and press the copy button. Does the bulb (tube) look okay?

Well first what do the bad quality prints look like what color strip or does black white work ok? Need more info.

If that lines are consistent with the red and blue and it does not appear during black and white print that means the cleaning blade in the affected color units need to be replaced

The blue toner cartridge or drum are damaged. First, try a different toner cartridge. This will probably eliminate the lines.

besides the obvious of changing the toner cartridge, is the print drum clean? Pop the machine open and look at the drum...is it all dirty looking? If it is, it will affect the quality of the print...although you would see spots and other things appearing in your printing if that were the case too... the fuser may be dirty too..(the part that gets hot) and that can affect it too..

call your tech services rep, he will tell you in detail what you are asking..........
have a good time,,,,,
