INK TANK – These do not have the print heads integrated.  The print heads are a separate, replaceable, maintenance item.  Do NOT do the paper towel method with these cartridges.

 

Not Recognizing

 

Verify they have the correct cartridges for their specific model printer.

 

There is a smart chip located on the end of the cartridge above the nozzles.  Check the chip for damage or debris.  You can use a Q-tip to gently clean off the gold contacts.

 

Verify the cartridge is installed correctly and fully inserted into the printer.  Also, check to make sure they are installing the correct color into the correct slot.

 

To remove and install these ink tanks into an HP Designjet 4000 printer do the following;

–          At the printer’s front panel, select the ink drop button, then Ink Cartridges > Replace Ink Cartridges Now.

 

–          The ink cartridge door is on the left-hand side of the printer.

 

–          Release the door catch by pressing on the top until it clicks.

 

–          Pull the door fully open.

–          Grip the blue tab in front of the cartridge you wish to remove.

 

–          Pull the blue tab down.

 

–          Then pull it outwards, towards you.

 

–          The cartridge comes out, in its drawer.

 

–          Lift the cartridge out of its drawer.

 

–          Check that the colored label above the empty slot in the printer matches the color of the label on the cartridge.  Insert the new ink cartridge into the cartridge drawer.

 

–          Position the cartridge at the rear of the drawer.

–          Slide the drawer and cartridge into the slot until it locks into position.

 

–          When all cartridges have been inserted, close the door (push it until it clicks shut).

 

Print Quality Issues

 

The printer has an Image Quality Print page that can be printed to help determine print quality problems.  To print this do the following;

–          At the printer’s front panel, select the printer icon, then information > internal prints > print image diagnostics > Drawings/text

 

Check the printed diagnostic pages to try to determine if the issue is occuring in one color or across multiple colors.

 

For any print quality related issue the printheads should be cleaned.  To clean the printheads do the following;

–          Go to the printer’s front panel and select the ink drop button.

–          Select Printheads > Recover printheads.  Cleaning takes about 2 to 4 minutes.

 

If the print quality issue still persists then that color printhead will need replacing.  The printheads are separate, replaceable, maintenance items and will need to be replaced after a certain period of usage.

 

Not Fitting

 

Verify they have the correct cartridges for their specific printer model.  Make sure the correct color is being installed into the correct color slot.  Check inside the printer for any obstructions.  Check the cartridges themselves for physical damage.
