How do you remove the front cover of HP Designjet Z3100 photo printer?

HP Recommended

I have read the service manual for the Designjet Z3100. It gives no information at all about how to remove the front cover. I need to remove the left cover to remove the electronics board, and replace a whining power supply fan. The service manual states that I can access a single screw near the bottom left HS of the front cover that holds the Left Cover in place. But there is a square shaped black plastic protrusion there that obscures  and prevents a ccess to where the screw should be.. something that is not even shown, let alone mentioned in the service manual instructions.  Anyone know how to remove the front cover and that square shaped protrusion to get to that screw??

6-17 of the service manual shows how to remove the front cover. Once the front cover is removed you can access the screw directly.

 Thanks.You're right.  I found it 2nd time around.  But the description and instructions given for removing the front cover do not actually apply for the 24" Z3100 photo printer.  There are other serious discrepancies for removal of the left side cover as well.  The most correct instructions I've found are posted on Youtube by Cigar Obsession as, HP Z3100 24 Inch Printer Rubber Drive Belt Replacement Kit Installation.. 4-5 minutes in. There are 3 release tabs, not four.. And they are not  simple to identify. One really needs this video tutorial.
