HP Designjet 650C Series Printers - Pen Rejection

In this document:

End of Support Drawer Statementback to table of contents

Hewlett-Packard guarantees support for five years after the end of production of its large format printers. Since the HP Designjet 650C has been out of production for a number of years, the parts and sub-assemblies may no longer be available to complete the repair. If the customer has a service agreement or contract follow normal contract call logging processes (regardless of parts availability).

If the printer is not covered by a service agreement or contract, notify the customer about parts availability issues that will limit the ability to perform printer repairs. Inform the customer about the benefits of HP's Trade Up program, and give them the Trade Up Web site http://www.hp.tradeups.com/login/login.asp. If the customer needs help in locating a local reseller, give them the reseller contact Web site at http://www.hp.com/usa/reseller/index.html. If the customer still requests service and parts are available, follow normal trade call logging processes to avoid escalation. If parts are unavailable for the needed service, do not log a CSO.
