THESE TONER CARTRIDGES DO NOT HAVE THE OPC DRUM INTEGRATED.  THE DRUM UNIT IS A SEPARATE, REPLACEABLE, MAINTENANCE ITEM.

There are 4 colors in this cartridge series; Black, Magenta, Cyan, and Yellow.

These are compatible cartridges so there will be differences from the OEMs.  These differences will not affect the function.

 

Not Recognizing

 

Verify you have the correct cartridges for your specific printer model.

 

There is a smart chip located on the end of each toner cartridge.  Check this chip for damage or debris.  A Q-tip or lint-free cloth can be used to gently clean the gold contacts.

 

Verify you have the correct color in the correct color slot.

 

To remove and install these toner cartridges into a Sharp MX-C311/401 Series printer do the following;

–          Open the front cover.

 

–          Pull out the color toner cartridge you are replacing.

 

–          Make sure you have the correct color cartridge for the color being replaced.  Insert the cartridge into the correct color slot.

 

–          Push the cartridge until it is fully inserted into the printer.

 

–          Close the front cover.

 

Print Quality Issues

 

There’s a small plastic protective piece under the cap which must be removed prior to installation.  This removes a piece of sealing tape that covers the toner shutter.

 

Shake the toner cartridge horizontally a few times to redistribute the toner powder inside the cartridge.

 

If black lines or colored lines appear the main charger that charges the drum can be manually cleaned by the user.  To clean the main charger do the following;

–          Press the power key on the control panel to turn off the panel power, and then switch the main power switch to the off position.

 

–          Open the front cover and remove the toner collection container.

 

–          Release the lock levers and open the main charger cover.

 

–          Flip down the charger cleaner lock (A) in the direction of the arrow, and lift the left end of the charger cleaner.  Move the charger cleaner to the left and pull it out.

 

–          Gently push the charger cleaner all the way and gently pull the charger cleaner out.  Repeat this 2-3 times

 

–          Repeat this each of the charger cleaning areas.  Clean with the mark of the charger cleaner facing down.  Holes to be cleaned by the charger cleaner are indicated by labels similar to (A).

–          There are a total of 4 places to be cleaned in the printer.

 

–          Replace the charger cleaner in its original position.  Insert the tip of the charger cleaner in toward the right and then press down on the end of the charger cleaner.  The charger cleaner will lock into place.

 

–          Close the main charger cover and rotate the lock levers in the direction of the arrows to lock the cover.

 

–          Install the toner collection container.

 

–          Close the front cover.

 

Streaking, lines, ghost imaging, and repeating image defects are drum related issues.  If the above cleaning doesn’t help then their drum unit may need replacing which is separate from the toner cartridges.

 

Not Fitting

 

Verify you have the correct cartridges for your specific printer model.  Verify the plastic protective pieces have been removed.  Ensure that the correct color is going into the correct color slot.  Check inside the printer for any obstructions.  Check the cartridge itself for physical damage.
