THIS TONER CARTRIDGE DOES NOT HAVE INTEGRATED DRUM UNIT. THE DRUM IS A SEPARATE UNIT FROM THE TONER CARTRIDGE.
This is a compatible cartridge so there will be differences from the OEM cartridge. These differences will not affect the function of the cartridge.
Not Recognizing
Verify you have the correct cartridge for your specific printer model.
There is a smart chip located on the end of the cartridge. Check to make sure the chip is not damaged or missing. Try removing the cartridge, disconnect the printer power cord for 10 seconds, re-connect the power cord, and then reinsert the cartridge.
To install the cartridge in an Okidata B431d do the following;
– Press the top cover release button and open the printer’s top cover fully.
– Pull the colored lever (1) on the right side of the toner cartridge towards the front of the printer to close the cartridge then remove the toner cartridge (2). Clean the top of the ID unit (3) with a clean, dry, lint-free cloth.
– Holding the cartridge by its top center with the colored lever to the right, lower it into the printer over the image drum unit from which the old cartridge was removed.
– Insert the left end of the cartridge into the image drum unit. Align it against the pins (1) on the drum unit. Then lower the right end of the cartridge down into the image drum unit (2).
– Pressing gently down on the cartridge to ensure that it is firmly seated, push the colored lever (1) towards the rear of the printer. This will lock the cartridge into place and release toner into the image drum unit.
– Gently wipe the LED array surface with a soft, dry, lint-free cloth.
– Lower the top cover and press it down to latch it closed.
Print Quality Issues
There is a white piece of plastic tape that covers the toner shutters on the cartridge which must be removed prior to installation.
Try rocking the cartridge back and forth a few times to redistribute the toner powder inside the cartridge.
Verify the cartridge is locked into the drum unit properly. Moving the lock lever to the back of the printer opens the toner shutters on the bottom of the cartridge which drops the toner into the drum unit.
If the printed page shows signs of fading, streaking or erratic marks, the problem may be cleared by generating a drum cleaning page as follows;
– Press the Online button to take the printer off line.
– Open the Manual Feed Tray and insert a sheet of plain paper between the paper guides.
– Press and hold down the Online button for at least 7 seconds.
– The printer prints a cleaning page.
– Return the printer online by pressing the Online button.
Ghosting, lines, streaking, and repeating defects will be a drum related issue. The drum unit is separate from the toner cartridge and is a replaceable, maintenance item. After a certain period of usage the drum will need replacing.
Not Fitting
Verify you have the correct cartridge for your specific printer model. Verify you are installing the toner cartridge into the pre-existing drum unit. If the cartridge appears too small then you are not installing the toner into the drum unit.
Make sure that the cartridge is locked properly in the drum unit. Verify that the white protective tape has been removed from the cartridge.
