Digital BW, The Print

Hi all,
         Quick question - in the picture of the 1280 CIS on the MIS 
website, it looks like the little ink cartridge clip things that hold the 
cartridges down on the 1280 aren't utilized.  Then I realized that the 
pictured unit is one of the earlier 1280's - I just got a silver 
one.  Let's just say that, while loading the UT carts for the first 
time...I managed to snap off one of those clips.

         Are the clips needed for the CIS?  As the printer seems to be 
printing fine now, and I do intend to get a CIS at some point, I was 
figuring that I would just leave it as is.  If those clips are needed, then 
I'll send it in to get fixed...
