NOTE 2: HP does not allow an automatic reset of the HP 564 / 564XL / HP 920 / 920XL electronic
chip on the cartridge after a refill, so the ink level indicator is sending a false message that the
ink level is low. Your cartridge is not low on ink, and nothing is wrong with your printer or
cartridges. The ink level indicator usually cannot be manually re-set, so the ink level indicator is
often not usable. However, losing this feature is not necessarily significant, because the ink level
indicator usually has substantial usable ink remaining when it shows "low on ink". If you observe
"Unauthorized ink", "non-HP ink", "counterfeit ink" or similar messages, you may ignore/dismiss
this message by pressing 'OK' once for each cartridge, so that the printer resumes its normal
operation.
**Typically the printhead should not reach it’s end-of-life until after a minimum of 8 or more
complete sets of cartridge changes; officejet models typically have a higher print page
throughput average, but this is not always the case. While some printheads may last 15,000+
pages others may only last 1000 pages, actual results will vary. The printhead will eventually fail
in time due to an internal micro-electronics failure, due to the following leading factors: general
customer print usage and printer care, printer duty cycle (i.e. # pages printed per month),
printing frequency (i.e. time between each print job), print mode (i.e. draft vs. normal) and
content printed (i.e. photos vs plain pages) and color mode (black and white only vs.
color/greyscale printing). Paper types used (i.e. plain paper, photo papers & matte/heavy bond
papers) and paper edge curl (i.e. duration in printer and/or exposure to low relative humidity)
can also quickly lead to premature printhead failures due to physical ‘head strikes’ of the paper
edges making repeated contact with the printhead nozzle plate surfaces.

HP 564/920 - UNAUTHORIZED / FRAUD INK MESSAGE / LOW INK
Regarding your recent inquiry about the HP 564/920 cartridge's 'LOW INK' or 'EMPTY INK' messages,
“Empty” and “Low Ink” alerts are COMPLETELY NORMAL for all HP 564/920 ink cartridges which have
been refilled! While at first this may be an unusual workflow, it does allow print operations to proceed.
The ink level monitoring feature CANNOT be reset since only brand new HP ink cartridges support ink
level monitoring.
As you just returned from the refill store, your ink cartridge(s) is full of ink - you may ignore low ink
warnings (along with any other nuisance message) and print normally until you observe one of the
colors to begin to fade.
Please watch video at the following link which explains normal operation when using refilled ink
cartridges:
