MAINTENANCE 8 Maintaining Your Plotter "Normal" Plotter Use "Normal" Plotter Use "Normal" plotter use means less than 20 pages per day (if medium-density E/A0 CAD plots), or 12 pages per day (if medium-density E/A0 image prints). If your drawings are smaller than E/A0, the number of pages per day can be higher. If you use the plotter less than this, it is unlikely you will need to get it serviced. If you use the plotter more than this, it is possible that, after a period of time, it will need to be serviced. The plotter itself keeps an internal count of total pages printed and total passes of the cartridge carriage. If the front panel periodically displays STATUS Maintenance advised this means that your use of the plotter has exceeded one of the following warranty limits: either 20,000 pages printed or 4,500,000 passes of the cartridge carriage. Contact your local HP dealer or HP service engineer to arrange a service. After the service the message will disappear. If you choose not to have the service, you may continue to use the plotter as normal, but may encounter a number of operational or print-quality problems. You can check your current count of pages printed and passes of cartridge carriage by printing the Service Configuration Plot. 8-3
