Okidata 44574701 and 44574901

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.

The 44574901 is the high yield cartridge and only works in specific printer models. Always double check your specific printer model to see which cartridge will be compatible.

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 the smart chip for damage or debris. A clean, soft, lint-free cloth can be used to gently clean the two gold contacts.

Make sure the cartridge is fully locked in the printer and that it is fully inserted.

To install the cartridge in an Okidata B411 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, lint-free cloth.

– Insert the left end of the cartridge into the 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 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 in the drum unit.

– Gently wipe the LED array surface located above the toner cartridge as illustrated below. It is important to clean the LED array surface anytime the toner cartridge is changed to prevent print quality issues. Do NOT use moisture of any kind.

– 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 signed of fading, streaking, or erratic marks, the problem may be cleared by running a cleaning page. To run a cleaning page do the following;

– Press the Online button to take the printer off line.

– Open the manual feed tray and insert a sheet of plain copy paper.

– 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.

If the toner is loose on the page and smears off then the paper type you are using may be too thick. The inside of the machine may also need cleaning or the imaging unit of the printer may be defective. Adjust the paper settings on the printer itself. If you are printing on labels or thicker paper than standard copy paper, including bonded paper, adjust the paper setting to match the paper type you are printing on. Sometimes, due to environmental conditions, it may be necessary to run a thicker paper setting even if you are printing on standard copy paper.

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 like the image below then the toner cartridge (1) has NOT been removed from the separate drum unit.
