Maintain the ink cartridges
During the normal lifetime of a cartridge, no specific maintenance is required. However, in order to
maintain the best print quality, you should replace a cartridge when it has reached its expiration date,
which is the manufacturing date marked on the cartridge plus 30 months.
Perform preventive maintenance
During the life of your printer, components that are used constantly can wear out.
To avoid having these components degrade to the point that the printer breaks down, the printer keeps
track of the number of cycles that the printer carriage makes across the axis of the printer, and also
monitors the total quantity of ink used.
The printer uses these numbers to track the need for preventive maintenance, and displays one of the
following messages on the front panel:
● Maintenance #1 required
● Maintenance #2 required
These messages mean that some components are nearing the end of their lives. You can continue
printing for quite some time, depending on your use of the printer. However, HP strongly recommends
that you contact your customer service representative and arrange for a preventive maintenance visit.
The service engineer can then replace the worn parts onsite, which will prolong the life of the printer.
