Preventive Maintenance
Introduction
About Preventive Maintenance
The purpose of scheduled preventive maintenance is to perform maintenance operations as required, in
order to avoid possible failures before they start and ensure a good performance throughout the product
life.
For each scheduled preventive maintenance action, there is an internal life counter in the firmware that
counts a variable related to the life of the component, like the number of liters of ink used, the square
meters of substrate printed, or the number of scan axis cycles (depending on the component/maintenance
action) since the last time the preventive maintenance action was performed.
When the internal life counter reaches the limit for a preventive maintenance action (set according to
testing and development), an alert is displayed on the HP Internal Print Server.
Preventive Maintenance Alerts and Actions
There are two types of preventive maintenance alerts: alerts that require a service engineer to complete
the action, and alerts that require only that the customer complete the action.
Service maintenance alerts
The HP Internal Print Server displays alerts whenever a maintenance action is required. There are four
alerts that require a Service Engineer, and must be performed according to the life counter value on the
right (which is calculated into a percentage automatically).
These procedures are included in this chapter See page 784.
Note 1: Corresponding counter in component usage of the service plot: 'Heater deflector usage since last
cleaning (cc)' and 'Curing deflector usage since last cleaning (cc)'
Note2: Corresponding counter in component usage of the service plot: ‘Carriage # cycles’.
Note 3: Corresponding counter is in intermediate tanks values, life cycles column, preventive maintenance
#3 will be displayed when one of the counter reaches this limit. 1 cycle = 1 refill done. (this info is
available only from FW 14.2.2.1).
Note 4: Corresponding counter is in component usage of the service plot : PPS # cycles, the thresholds
will be moved from 2000 to 8000 within a future firmware version after version 14.2.2.1.
