HP Officejet Pro L7380 All-in-One Printer - Manual (Page 101)

If you need to call HP, it is often useful to print the self-test diagnostic page before
calling.
1. Printer Information: Shows device information (such as the product name, model
number, serial number, and firmware version number), the accessories that are
installed (such as the duplexer), and the number of pages printed from the trays
and accessories.
2. Ink Cartridge Status: Shows the estimated ink levels (represented in graphical
form as gauges) and the part numbers and expiration dates of the ink cartridges.
NOTE: The ink levels shown are an estimate only. Actual ink volumes may
vary.
3. Printhead Status: Shows the status of the printhead health and the part numbers,
first-installation dates, and end-of-warranty dates of the printheads, as well as the
accumulated ink usage. The status options for the printhead are: good, fair, and
replace. If the status is 'fair,' then the print quality must be monitored, but the
printhead does not need to replaced. If the status is 'replace,' then the printhead
should be replaced, as the device will not function until it is.
4. Event Log: Shows a log of recent events that have occurred.
