 Preventive Maintenance

781

The reason for this is when doing a cycle of the PPS (raising up and lowering back), the counter does not 

increase by 1, but by 4 on average, so the threshold will be increased to 8000 instead of 2000.

Note 5: Corresponding counter in component usage of the service plot: Tube ISS # cycles.

Printer with serial number ok (SG94S1F001), on one which the preventive maintenance #5 has not been 

performed (tube not replaced), will have a preventive maintenance #5 displayed with the number of 

cycles of the scan axis reaches 900 000 (from FW version 14.2.2.1).

Once the preventive maintenance #5 has been applied, and the reset from the service menu has been 

done (PMKIt#5), this preventive maintenance #5 is disabled (even if it is all the time displayed). It remains 

the preventive maintenance #2 (carriage chain assy replacement).

It is very important to reset the maintenance kit usage each time you perform preventive maintenance 

action See page 420.

The HP Internal Print Server displays alerts whenever a maintenance action is required. The following 

seven alerts require action from the customer, and must be performed according to the life counter value 

on the right (which is calculated into a percentage automatically).

For more information about these procedures, refer to the Maintenance and Troubleshooting Guide.

Note 1: The corresponding counter in not visible in the service plot, but can be calculated from the 

preventive maintenance chapter, by applying, at the line 'heating sensor', the column 'capacity'*'current 

usage'.

Note 2: The corresponding counter is available in the service plot, in the component usage section, Line 

sensor since last clean (milliliters) with a corresponding threshold: 80 000 000 (80l), number reported 

with 000 more than ml.

Note 3: The corresponding counter is available in the service plot, in the component usage section: Usage 

oil reservoir (m), with a corresponding limit of 500 000 m (500km of the carriage movement distance).

Note 4: The corresponding counter is available in the service plot, in the component usage section: Usage 

slider rods (m), with a corresponding limit of 3 000 000 m (3000km of the carriage movement distance).

Note 5: The corresponding counter is available in the service plot, in the component usage section, 

Carriage lid usage (milliliters), with a corresponding threshold: 80 000 000 (80l), number reported with 

000 more than ml.

Note 6: The corresponding counter is available in the service plot, in the component usage section, Ink 

deposit level (cc) , with a corresponding threshold: 136 000 (136l).
