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.

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.

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.
