This section describes the procedure for checking the platen gap (PG) necessary when removing the Printhead or in a similar case.

When checking the PG, make sure of the following.

• Move the Carriage Assy by pulling the Timing Belt.
• Be careful not to damage the nozzle surface of the Printhead with the thickness gauge.

Tools

• Thickness gauge: 1.37 mm (x2), 1.47 mm (x2)
• Teflon Tape: Commercial item (thickness: 0.08 mm)

Checking procedure

1. Check the PG position is set to PG 1
2. Move the Carriage Assy to the center of the printer.
3. Place the thickness gauges (1.37 mm) on the positions
4. Pull the Timing Belt to move the Carriage Assy to both ends and confirm the Carriage Assy does not touch the thickness gauges. If the Carriage Assy comes in contact with the thickness gauges, the PG is narrower than the standard value.
5. Move the Carriage Assy to the center, and replace the thickness gauges (1.37 mm) with the thickness gauges (1.47 mm) on the same positions as Step 3.
6. Pull the Timing Belt to move the Carriage Assy to both ends and confirm the Carriage Assy touches the thickness gauges. If the Carriage Assy does not come in contact with the thickness gauges, the PG is wider than the standard value.
