• 1/2 inch open-end wrench
• 5/8 inch or 7/8 inch open-end wrench
5.2 Preparation
1. Check to see if there is a full ink bottle in the machine by opening
the ink door. If a full ink bottle is present, remove it.
2. Power off the Model 5200/5400 and disconnect the power cable.
3. Remove the front cover by loosening the five large captive

station.
5.3 Removal
1. Loosen the screw for the ink bottle guide. Lower the guide and
retighten the screw (1, Figure 6-5).
