I don't know much about this as I got it off a printer in a garage clean out.  Used OEM HP OfficeJet 6700 6600 7500a Printer Output Paper Tray CN582-40023 CN583-40021 as shown.  It is used (i.e. scuffs, dusty, etc).  Please see the pictures as they are part of the description.  Again, check to make sure that this will fit your application (plumbing, etc).  What you see is what you get.  Look the pictures over and judge for yourself!

AS WITH ANY ITEMS, NO RETURNS ACCEPTED.  Item is for sale locally, so I reserve the right to end listing early.  International buyers through E-bay's global ship only.  It will take a few days to get item shipped.  Please let me know if you have any questions.  Thanks for looking!
