Scheduled Maintenance
In some segments of the printer market, the customer tends to print more than the maximum number of
prints that the throughput allows, exceeding by far the limit of the design. When this happens the customer
runs into print quality problems and continuous Printer failures.
The purpose of scheduled preventive maintenance is to avoid these failures - ensuring a good performance
during all the product life.
Level of Printer Usage
Normal printer use means 6,000,000 Carriage Cycles (which corresponds to approximately 100,000
A0 prints on average). Under normal usage conditions, it will be approximately 5 years before the printer
needs maintenance. If the printer is used more than the normal usage conditions, then it will need
maintenance service much more frequently.
One of the EEROM counters is assigned to counting the number of carriage cycles. When certain
components of the Printer exceed this amount, the front panel displays the following message:
