maintenance • Keep the printheads sealed in the original packaging until ready to use. • Keep the printheads that are open in the printer or sealed in a plastic bag separately. Each printhead should have its own bag. • Store printheads at room temperature. • Power off the printer by pressing the POWER button. Powering off with the POWER button ensures the Carriage is at the Service Station position. The Service Station caps the printhead ink nozzles to prevent them from drying. • Install printhead by Install-By Date to maximize warranty. • If a printhead is removed and later replaced by one with the same serial number, the printer will only perform pen alignment.
expiration dates • Install-by date : The Install-by date is printed on the retail box for printheads. Install the printheads before the date given in the Install-by date for optimized performance. • End-of-Warranty date : The End-of-Warranty date is printed on the printheads. The End-of-Warranty date specifies the date by which the warranty period for the printheads end. setup & configure hp restricted 2-27
