Refer to our support instructions: http://inkjet411.com/?page_id=1457

2. To verify the lines are clear and working correctly, print the “INK RECOVERY TEST PRINT” from our

Test Prints page: http://inkjet411.com/?page_id=146

3. Run the self-test print (under maintenance/tools menu), this will verify nozzle performance and that

each color is firing a solid band of color (i.e. you should not see any bands or missing lines in the

pattern). This is also a good test to help isolate which color (or portion of the electronic PRINTHEAD*)

may be causing the issue.

4. It is also possible that either of the PRINTHEADs may have poor connectivity with the rear electrical

pad/interface. It is suggested that you attempt to re-seat (i.e. remove and re-install) the Cyan/Magenta

and/or Yellow/Black PRINTHEAD assembly. Click here for instructions:

- Also check warranty ‘end date’ on PRINTHEAD assembly while it is removed from printer (refer to #7

below).

NOTE: HP’s PRINTHEAD removal/replacement instructions can be found here:

5. Return the refilled cartridge to your refiller and have them check ink levels and weigh the ink

cartridge.

6. It is possible a PRINTHEAD 'firing' or electronic failure issue is present (…electronic assembly which

performs the actual 'firing' of drops onto the page)*. However, in most of these cases you would

normally get either a ‘Printhead failed’, ‘Printhead missing, or ‘Replace Printhead’ alert message or you

would observe unrecoverable poor/severe print quality. Refer to video to see how the Printhead works:

7. Check the 'WARRANTY ENDS' date on the PRINTHEADS as it may be expired*. See 7

photo at the

following link: http://inkjet411.com/?page_id=1457

8. If either PRINTHEAD is expired then it may need to be replaced.*

9. If the above resolutions do not correct the issue, then re-priming or replacement of the suspect

PRINTHEAD may be required to fully recover the ink delivery system.

NOTE: If you DO NOT observe a PRINTHEAD alert or error message, but instead observe substandard

print quality (or completely missing colors) and suspect the PRINTHEAD may be clogged, then you

may want to consider flushing the PRINTHEAD using an advanced 3

party procedure:
