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

behind the sheet metal as shown below. If a customer is unwilling to do this

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