Remove the Left, Top, and Right Covers
Removing the Left Cover allows access to the left side of the Platen for
removal of the Carriage Assembly, Carriage Drive Belt, Tension Assem-
bly, and the Cutter Activator. Also located on this side is the ink
reservoirs and the Ink Delivery System portion that is connected to the
reservoirs. Removal of the Left Cover is a requirement to remove the
Lower Roller Assembly and the Vacuum Fan(s) from inside the Platen.
Removing the Right Cover provides access to the Main Printed Circuit
Board (MPCB), Display and Keypad circuits, Servo Motor, AC Entry
Module and the Power Supply Cooling Fan.
The Top Cover needs to be removed before any of the other covers can be
removed. It also gives access to the Carriage Assembly and the Service
Station when in the open (up) position and the Carriage is at the
Carriage Access position.
To remove the Top Cover:
1. Put the Top Cover in the open position by lifting the front of the
Cover to the full upward position.
2. Depress and hold the retracting stop assembly located on the left
side of the Top Cover to disengage it from the Left Cover.
3. Lift up on the left side of the Top Cover until it clears the Left Cover
while still depressing the retracting stop assembly, then slide the
cover to the left to disengage it from the Right Cover.
