8. Check the 4th line at the top of the printed report; an electrically good/stable PRINTHEAD will
state “Pen Status: Pen OK”………if any other message is displayed then the PRINTHEAD may have failed
and may need to be replaced.
C. Clean printer's service station - see link for cleaning instructions.
NOTE: A dirty service station can cause cross-contamination between the colors:

D. If the color shift / color intensity issue only occurs with printed content from your computer,
etc...then the printer driver settings may be set to either 'draft mode' or 'greyscale', etc.. Click here for
more information: http://inkjet411.com/?page_id=1432
E. Perform a 'Clean Printhead' from the printer's control panel menu if print quality issues persist or if
you observe a color shift as there could still be an air bubble in the ink cartridge(s), or between the
cartridge(s) and PRINTHEAD. Refer to video: http://inkjet411.com/?page_id=1983
F. Return HP920/920XL black ink cartridge to your refiller store and ask them to refill it since the ink
cartridge color continues to produce a color shift in printed output.
G. Worst case scenario the PRINTHEAD* may simply be damaged or at end-of-life and may require
replacement, but usually you will see error messages like "Incompatible Printhead" or "Ink Delivery
System Failure" when this occurs. Please note that failure of the printhead is unrelated to the refilled
cartridges as the PRINTHEAD will eventually fail in time*.
NOTE: To perform additional HP920 PRINTHEAD* diagnosis, please visit our 'HP Printer Diagnostic Test'
page: http://inkjet411.com/?page_id=1813
*The HP 920 ink-series printer models have an electronic PRINTHEAD (customer replaceable) within the
base of the carriage assembly (responsible for pulling ink from the 4 ink cartridges and then firing the ink
droplets onto the paper) – the PRINTHEAD will eventually fail over time depending on printed content,
frequency of printing and printer duty cycle (i.e. rated for max. of ~15,000 printed pages over life, but
the average throughput is more in the neighborhood of ~9000 pages).
