Introduction 1 Introduction This Printer Maintenance Guide describes the regular inspection and maintenance procedures to be performed by users. The maintenance procedures described in this maintenance guide are also available in your printer's User's Guide. Failure to perform daily maintenance procedures may result in damage to your printer printheads and will invalidate your warranty. For further user information about the HP Designjet 8000s Printer series, please refer to the User's Guide and warranty information that came with your printer. Before starting the maintenance procedures, spend some time reading the safety precautions and notes which are contained in the User's Guide. WARNING! Never switch off the printer without following the correct procedures. Even with the storage liquid installed, never leave the printer off for more than four weeks. Leaving your printer off for more than four weeks can cause permanent damage that cannot be repaired. In all other cases make sure you observe the appropriate maintenance guidelines. CAUTION The printer has an internal clock which allows it to wash the printheads automatically, flushing some ink through the printheads, which keeps the printheads in good condition. The printer automatically washes the printheads regularly after the last printing process. If the printer is switched off or media is not loaded, this process does not happen. If the ink does not flow through the printheads from time to time, the ink will dry inside the nozzles, reaching a point where it is impossible to recover them and the printheads will fail. If the printer must be switched off for a long period of time, the customer must use either the optional HP Ink System Cleaning Kit or HP 780 Ink System Storage Kit to recover or protect the printheads. Automatic maintenance and cleaning will ONLY be performed when the printer is switched on and powered up with media loaded. If you switch it off on the front panel or with the power switch on the rear of the printer this maintenance will NOT be performed. ENWW 1
