Can't open drum unit

The error message "print drum error and front cover open" on a Konica Minolta Pagepro 1590 MF multifunction printer typically indicates that there is a problem with the print drum unit, and that the front cover of the printer is not properly closed. Here are a few steps you can try to resolve the issue:

1. Close the front cover: Make sure that the front cover of the printer is properly closed and latched shut. This will help to ensure that the print drum unit is properly seated and can function properly.
2. Check the print drum unit: Remove the print drum unit from the printer and carefully inspect it for any visible damage, such as scratches or cracks. Make sure that the drum is not damaged, and also make sure that it is not dirty. if it is dirty clean the drum with a dry and soft cloth.
3. Slide the blue tab: Make sure that the blue tab on the print drum unit is in the correct position. The tab should be sliding easily back and forth across the drum unit and the drum unit should be locked in place.
4. Reinstall the print drum unit: If the print drum unit is not damaged and the blue tab is in the correct position, then re-install the unit into the printer.
5. Reset the printer: Once the print drum unit is reinstalled, try resetting the printer by turning it off and unplugging it for a few minutes before plugging it back in and turning it on again.

If you have done all these steps and the problem persist, it's possible that the print drum unit itself is faulty and will need to be replaced. If that's the case, it's best to contact a service technician or the manufacturer for help in replacing the unit.
Please note, it's always recommended to refer to the user manual of the printer or consult with an authorized technician before taking any steps, this will help you to avoid any possible damage to the printer or any other parts.

Once you have the new drum unit, and are ready to install, just open the front door. Slide out the toner cartridge/drum unit combination assembly. Press the release tabs on either side of the toner cartridge and lift it up and out of the drum unit. Set it aside. Unpack the new drum unit and go over the installation instructions if you have them. Basically you are just removing all of the packing materials for the drum unit. Once that is done you need to install the old toner cartridge into the new drum unit. It just slides in and locks down. Then install the whole assembly back into the printer.
Leave the front door open, and press the Options key on the control panel.
The display will show "REPLACE DRUM - 1.YES 2.NO".
Press 1 to reset the drum count.
Close the front cover.
This should complete the installation process. Just run a test copy to verify all is well.
Good Luck and Thank You for using Fixya.

Hi,
waste toner is located inside drum unit.
Slide cover to the left, then open toner cover and remove toner, then open upper cover from rightsideway.By metal handle slide out the drum/toner unit out in right side.On top of the drum unit is cork. Open it and vacume out all the waste toner.
Put it back in and close all covers.

Hope that helps!

This machine has more than one drum unit, its a color machine. You have three color and one black as well as 4 developer units. You need to know which one needs to be removed. Shut the machine down unplug it from the wall. The upper units are the drums, which should easily slide out. If I remember correctly you have to flip up a clip on the front of each drum unit first to slide the drum out.

Commonly caused by High voltage discharge or arcing from a dirty primary charger corona and grid.

You need to clean your drum unit.

Open the front door and pull out the Drum unit.

Look on top of it for a small (usually) blue slider, sitting in a 10mm slot that runs the length of the Drum unit. This is the corona cleaner.

Slide this back and forth about 6 times, ensuring you return it to the original starting position.

Reinstall the Drum unit and try printing.....

The green tabs that you have to slide are under the color cartridges, so remove the three color cartridges and you will see three green tabs, to slide the tab across the wire you have to first open the translucent plastic wire cover, then slide the green tab across the wires and return it to it's original position, close the wire covers, replace the color cartridges, and reassemble the printer. All the Best

To change the drum you have to slide the plattened cover to the left,like you do when removing a paper jam,open the top cover,you will see a handle that you pull to remove the defeloping and drum unit,remove the drum and def unit.
The drum is attached by two clips on top of def unit,unlock the drum from the def by releasing that clips,slide te drum protecktion plate to the rear and remove the drum.insert the new drum by reversing this steps.
If your image of your copies is not bad you can remove the waste toner in the drum unit before replacing it.On top of the drum there are two plugs open them and remove the waste toner,make sure you remove all of the waste toner.Then that message will go away.

no screws to take out make sure all the toner levers are locked down so toners cant slide out. kust below the toners is a lever that will open the drum cover when you open this it reveals the drums just slide them out

please open right cover and out in your toner box you saw a screw is open and turn in fornt developer unite open your drum unite
