INK TANK – THESE DO NOT HAVE THE PRINT HEADS INTEGRATED.  DO NOT DO THE PAPER TOWEL METHOD WITH THESE CARTRIDGES.

 

Not Recognizing

 

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

 

If the printer is not recognizing that a cartridge is installed at all there’s a chip located on the front inside of the cartridge.  Check the chip for damage or debris.  A Q-tip can be used to reach and wipe the gold contacts.

 

Make sure the cartridge is firmly pressed into place.  If the cartridge is not pushed down far enough the chip will not make proper contact.  Also try removing then reinstalling the cartridge.

 

To remove and install this cartridge in a Hasler WJ250 machine do the following;

–          Open the top cover and lift the blue lever.

 

–          Press on the front of the ink cartridge (1), then on the right hand side (2) in order to remove it.

 

–          Remove the ink cartridge.

 

–          Insert the new cartridge into the slot.

 

–          Press on the front of the ink cartridge (1), then on the left hand side (2) in order to lock it.

 

–          Lay down the blue lever and close the top cover.

 

Print Quality Issues

 

A printhead cleaning should be performed any time there are print quality issues.  To run a printhead cleaning on the Hasler WJ250 do the following;

–          Press the MENU key and then select CLEAN.  The machine will begin the printhead cleaning process.

 

If the first cleaning doesn’t resolve the issue run a second cleaning.  Printhead cleaning does consume ink so it should be done sparingly.

 

The paper towel method can be performed to the separate printhead.  In order to do this you will need to remove the printhead.  To remove and install the printhead on a Hasler WJ250 do the following;

 

–          Open the top cover and printhead cover; the printhead will move to the replacement position.

 

–          Press on the front of the printhead in order to remove it.

 

–          Remove the printhead.

 

–          Perform the paper towel method to the two printhead located on the bottom.

 

–          Insert the printhead back into the slot.

 

–          Lock it in postion by pinching the rear of the printhead.

 

–          Close the printhead cover and top cover.

 

The printheads will need to be replaced after a certain period of usage as part of the regular maintenance of the printer.

 

Not Fitting

 

Verify you have the correct cartridges for your specific printer model.  Check inside the printer for any debris which may be obstructing the cartridge from going in properly.  Check the cartridge itself for physical damage.
