Line through the colors

Deep cleaning uses up a lot of ink. Is it possible that you are out of ink?

For severe print quality/missing color issues there could be an air bubble/air gaps in the printer ink lines or a portion of the PRINTHEAD is dry, so you should first perform a Clean PrintHead procedure from your printer control panel.
NOTE: If one or more the colors were previously dry fired during printing (i.e. if you continued printing using only a few colors to one, air may have been accidently ingested into the ink lines between the cartridge(s) and PRINTHEAD. To recover from this problem, you may have to run the Clean Printhead procedure 2-3 times.
If a problem persists then it is suggested to review the steps outlined on the following HP 920 support pages, including printhead removal/printer cleaning and service station cleaning. It is suggested you refer to printer manufacturer instructions first as the Inkjet411 procedures are provided for general guidance purposes only. A dirty service station can cause poor image quality and/or ink cross-contamination between different colors:

If the problem still cannot be corrected, then the PRINTHEAD may be dry and may need to be flushed (i.e. with warm water as it could have dried out, but this is a function of how much you print). Remove and soak in hot water for 5 minutes...thoroughly dry printhead prior to re-installing. Retest.

Worst case scenario the PRINTHEAD may simply be electrically damaged or at end-of-life (typically fails between 3,000 and 5,000 printed pages) and may require replacement, usually accompanied by error messages like Incompatible Printhead or Ink Delivery/System Failure. NOTE: The PRINTHEAD will eventually fail in time. For more information on the how the PRINTHEAD works, watch the video here: http://inkjet411.retailinkjet.com/?page_id=1983
To verify Printhead performance, run the Tap 41 diagnostic test, (Pen Status: Pen OK).....for printer model instructions please visit:

have you already replaced the ink of your black?..

BETTER SOLUTION IS IF YOU TAKE MORE PHOTOS I SUGGEST YOU BUY ORGIINAL INK CARTRIDGES.THEN YOU CAN DO ONE TIME REFILLING.ITS OK.

AGAIN IF YOU TRY REFILL SAME CARTRIDGE MAY LOSS YOUR PAGE YEILD. IF U WANT USE REFILLED CARTRIDGES AGAIN BUY VIRGIN CARTRIDGE FROM REFILL STORE AND MAKE REFILL. OTHERWISE INK WILL FINISH SOON.

FOR BLACK INK U SHOULD REFILL OR BUY NEW ONE NOW. BECOS BLACK INK FINISHED ALREADY. THATS WHY YOU GETTING BLUE PRINTING....OOOOOOOOOK DEAR...

If a line doesn't print, the ink is out of the cartridge for that inkjet cartridge color. Replace the cartridge. Deep cleaning can use a lot of ink up at a time.

Deep clean should clean the printhead, but it's an expensive way to do it, since a lot of ink is used.

Do you have lines of non printable areas? Maybe replacing the printhead will help.

May be out of ink in certain nozzles on the printhead.

The head of your printer cartrige (black) are not detected by the printer because it was damage and need to be replace. So that no more black ink could print anyway.

You need a new printhead,QY6-0049-000, around $50.00.

just wipe the nozzles or the printhead .on a wet cloth...using DI(deionize water) to remove the clogs that cover nozzles...and then deep clean the printhead using the printer panel features...

good luck..

remove the cartridges and the printhead
do a deep clean by pressing menu>clean printhead
see if it will make a difference then also check your ink levels..
