2) its being pulled out slightly from the front of the printer. Typically this is most
visible at the center protrusion of the guide – between the Magenta and
Cyan cartridges as shown below:
When this guide is pulled away from the printer frame, a gap may be visible
between the guide and the frame and a plastic tab is visible just above the
cartridge slot that should not be.

This issue may be addressed by snapping the guide back into position. In order to
do this, it is necessary to use a small flat-blade screwdriver to help move the tab

themselves, a technician may be dispatched to perform the action:

result of removing or installing print cartridges.
