Blue Line When I Print A Document With Konica Minolta C369

1. Damaged toner cartridge

If the blue toner cartridge is damaged, it could be causing the blue line to appear. Try replacing the blue toner cartridge to see if that solves the problem.

2. Dirty or damaged imaging unit

The imaging unit is responsible for transferring the toner from the cartridge to the paper. If the imaging unit is dirty or damaged, it could also cause a blue line to appear. Try cleaning the imaging unit, or if necessary, replacing it.

3. Problem with the transfer belt

The transfer belt is responsible for transferring the toner from the imaging unit to the paper. If the transfer belt is dirty or damaged, it could also cause a blue line to appear. Try cleaning the transfer belt, or if necessary, replacing it.

4. Problem with the laser unit

The laser unit is responsible for creating the image on the drum. If the laser unit is dirty or damaged, it could also cause a blue line to appear. Try cleaning the laser unit, or if necessary, replacing it.

If you have tried all of the above and you are still seeing a blue line, it is best to contact a Konica Minolta service technician to help you troubleshoot the problem.

Here are some additional tips for troubleshooting the issue:

Try printing a test page to see if the blue line appears on all pages.

Try printing a document in black and white to see if the blue line still appears. If it does not, then the problem is likely related to the color print system.

Try cleaning the printer's print head and other internal components.

Check the printer's firmware and make sure it is up to date.

If you are unable to resolve the issue yourself, please contact a Konica Minolta service technician for assistance.
