One Year Exchange Warranty.

The part you will receive includes a One Year Exchange Warranty. 

It is verified to work without errors by me -- A HP Certified Technician trained to work on the HP DesignJet 500 series printers since they were first introduced back in 2001. 

How does a defective core exchange work? 

THIS ITEM REQUIRES THE RETURN OF YOUR DEFECTIVE PART. 

OPTION #1: 

I can ship immediately. SHIPPING TODAY REQUIRES A $100.00 REFUNDABLE CORE DEPOSIT. An invoice for the CORE DEPOSIT will be emailed to you via Paypal (credit card accepted). A pre-paid shipping label for the return of the defective part will be included in the package (US customers only). 

OPTION #2: 

I send you a pre-paid shipping label for the return of the defective part. When the package tracking number for your defective part is registered on the USPS website, your replacement part will be shipped to you.

Please confirm that you have a Designjet 500 printer. The 500 GL/2 Card will not work in a Designjet 510 printer. I have had several customers with a Designjet 510 purchase the 500 GL/2 Card. The 500 GL/2 Card does not work in their printer. This will caused delays with exchanging the 500 card for the 510 card.
