Printer Jammed - now it's broke!

HP Recommended
HP OfficeJet PRO 7740 Series
Mac OS X 10.11 El Capitan

My printer recently jammed - very badly. While clearing the jam, a very clear, thin strip of plastic that is placed just behind the ink cartridge came unattached from the right side. Now - the printer will  not print when I try....it simply starts to spool the paper to try to print, and then says it is jammed. 

 

Any idea on what this piece is and how to fix it?

That is the encoder strip- - - your printers carriage reads the lines on that strip so it knows how far to travel on it's axis during operation.

I suggest you do a google search for your printers service manual and download the pdf. then you can follow the steps in the manual for replacing the encoder strip. if it came off, it's broke because they are usually held on each end with a screw.

Good Luck,
