Checking Epson XP-15000 | XP series Platen Gap

This section describes the procedure for checking the platen gap (PG)

 The standard range of the PG is as follows:
• Standard: 1.2 ± 0.1 mm (PG -)
 This adjustment should be carried out with the mechanism in the minimum PG position (PG -) before installing the CR Scale.
 PG changes approximately 0.08 mm by moving one notch of the parallel adjustment bushing

• Tools:    Thickness gauge: 1.1 mm, 1.3 mm

Before doing the Checking Epson XP15000 | XP series Platen Gap Adjustment, check the following:

• The rib A on the CR Shaft Gear should be set vertically upward in the PG position (PG -).
• The center of the notch of the Parallel Adjustment Bushing on the side of the printer is set in the position of the rib B.

How to check Epson XP-15000 | XP series Platen Gap?

Warning:

When performing the PG adjustment, make sure of the following.
– Move the CR Unit by pulling the top pf the CR Timing Belt.
– Be careful not to damage the nozzle surface of the Printhead with the thickness gauge.
– PG Adjustment should be carried out with the new ink cartridges are installed. The ink cartridges should be installed with the CR Unit is in the ink cartridge exchange position.(See Printhead (p53).)
–  To maintain the parallelism adjustment bush’s designed performance for holding the CR Guide shaft, if the bush is deformed such as being scratched with a screw mark, make sure to replace it with a new one.

Adjustment of the 0-digit side

• STEP 1. Loosen the screws (x4) on the CR Guide Rail, the each screw securing the CR Scale Holder and CR Spacer, and the screws (x2) securing the Parallelism Adjustment Bushing on the left/right of the printer. (See Figure 2.)
• STEP 2. Move the CR Unit to the center of the printer and place the thickness gauge (1.1 mm) on the position A shown in Figure 3.

• STEP 3. Move the CR Unit to the 0-digit side while pushing the CR Guide Rail from the top and check if the CR Unit touches the thickness gauge.
  • When the CR Unit touches the thickness gauge
    Move the CR Unit to the center, move the Parallelism Adjustment Bushing at the 0-digit side by one notch in the + direction. (See Figure 2.)
  • When the CR Unit does not touch the thickness gauge
    Move the CR Unit to the center, move the Parallelism Adjustment Bushing at the 0-digit side in the – direction until the CR Unit touches the thickness gauge and repeat this procedure from Step 3.
• STEP 4. Move the CR Unit to the 0-digit side again while pushing the CR Guide Rail from the top and check if the CR Unit touches the thickness gauge.
  • When the CR Unit touches the thickness gauge
    Move the CR Unit to the center, move the Parallelism Adjustment Bushing at the 0-digit side by one notch in the + direction and repeat this procedure from Step 3. (See Figure 2)
  • When the CR Unit does not touch the thickness gauge
    Move the CR Unit to the center and go to Step 5.
• STEP 5. Remove the thickness gauge (1.1 mm) and place the thickness gauge (1.3 mm) on the position A shown in Figure 3.
• STEP 6. Move the CR Unit to the 0-digit side and check if the CR Unit touches the thickness gauge.
  • When the CR Unit touches the thickness gauge
    Move the CR Unit to the center and remove the thickness gauge, and secure the screw on the Parallelism Adjustment Bushing at the 0-digit side. Go to Step 7.
  • When the CR Unit does not touch the thickness gauge
    The PG is too wide, so move the CR Unit to the center of the printer and repeat this procedure from Step 2

Adjustment of the 130-digit side

• STEP 7. Place the thickness gauge (1.1 mm) on the position B shown in Figure 3).
• STEP 8. Move the CR Unit to the 130-digit side while pushing the CR Guide Rail from the top and check if the CR Unit touches the thickness gauge.
  • When the CR Unit touches the thickness gauge
    Move the CR Unit to the center, move the Parallelism Adjustment Bushing at the 130-digit side by one notch in the + direction. (See Figure 2.)
  • When the CR Unit does not touch the thickness gauge
    Move the CR Unit to the center, move the Parallelism Adjustment Bushing at the 130-digit side in the – direction until the CR Unit touches the thickness gauge and repeat this procedure from Step 8.
• STEP 9. Move the CR Unit to the 130-digit side again while pushing the CR Guide Rail from the top and check if the CR Unit touches the thickness gauge.
  • When the CR Unit touches the thickness gauge
    Move the CR Unit to the center, move the Parallelism Adjustment Bushing at the 130-digit side by one notch in the + direction and repeat this procedure from Step 8. (See Figure 2)
  • When the CR Unit does not touch the thickness gauge
    Move the CR Unit to the center and go to Step 10.
• STEP 10. Remove the thickness gauge (1.1 mm) and place the thickness gauge (1.3 mm) on the position B shown in Figure 3.
• STEP 11. Move the CR Unit to the 130-digit side and check if the CR Unit touches the thickness gauge.
  • When the CR Unit touches the thickness gauge
    Move the CR Unit to the center and remove the thickness gauge, and secure the screw on the Parallelism
    Adjustment Bushing at the 130-digit side. Go to Step 12.
  • When the CR Unit does not touch the thickness gauge
    The PG is too wide, so move the CR Unit to the center of the printer and repeat this procedure from Step 7.
