How to Replace a Wiper Blade and Set the Proper Wiper Blade Height in Pilot Software

This guide explains how to properly replace and calibrate the **wiper blade** on a **Prestige L2 DTF printer**, including mechanical installation and final height calibration using DTF Station Pilot. Preparation & Safety

1. Turn the printer **ON**.
2. Open the **front cover**.
3. Press and hold the **Left Arrow** key until the carriage moves fully to the left.

1. Turn the printer **OFF**.
2. Unplug the power cable.
3. Wait **30 seconds**. Remove Capping Station Cover

1. Remove **five screws** securing the capping station cover.
2. Remove the cover.

• Do **NOT** use a power drill (risk of stripping plastic threads).

Remove Old Wiper Blade

• Use a **lint-free cloth** and **cleaning solution**.
• Clean all visible ink buildup around the capping station.

1. Locate and remove the **two screws** securing the wiper blade bracket.
2. Remove the entire bracket assembly.

• Take a **photo** of the original wiper blade position for reference.

1. Remove the **three screws** holding the wiper blade.
2. Remove the blade.

Install New Wiper Blade

• Clean:
• The wiper blade bracket
• The capping station mounting area

• The **curved edge** of the wiper blade must tilt **toward the L-bracket side**.

1. Insert **one screw** through the L-bracket side into the opposite metal panel.
2. Install the remaining **two screws** the same way.

• Do **not** fully tighten.

Examples:

• Match the original blade height as closely as possible.
• Ensure the blade is:
• **Straight**
• **Even across both print heads**
• ❌ Crooked blade → wipes only one head
• ✅ Straight blade → wipes both heads evenly

Reinstall Assembly

• Once aligned, slowly tighten all three screws.

1. Place the bracket back onto the capping station.
2. **Do NOT place past the ridge line** (this raises the blade too high).
3. Secure with **two screws**.

1. Place the capping station cover back on.
2. Secure with **five screws**.

1. Plug the printer back in.
2. Turn the printer **ON**.
3. Wait until status shows **Idle**. Software Calibration (Critical)

1. Open **DTF Station Pilot**.
2. Go to **Advanced**.
3. Enter password: **111**
4. Click **Confirm**.

• Locate the **Inkstack Height** value.
• This value controls the **effective height of the wiper blade**.

1. On the printer, press **Left Arrow once** to disengage from the capping station.
2. Move the carriage left/right over the wiper blade.
3. Check for contact: If touching → blade is too high

• If no contact → blade is too low

1. Click **Confirm** to test the current value.
2. Adjust value incrementally: Lower value → blade goes down
3. Click **Confirm** after each change. Goal: Blade touches the print head **without bending**. Final Verification

• Higher value → blade goes up

1. Start a **Head Cleaning**.
2. Observe the wipe: ✅ Correct: smooth wipe, no bending Save & Backup Configuration

• ❌ Too low: no contact
• ❌ Too high: blade flicks ink sideways

1. Click **File → Save**.
2. Click **OK**.

1. Go to **Operation**.
2. Click **Initialize**.

1. Go to **Firmware**.
2. Click **Export Firmware Configuration**.
3. Save with filename including today’s date.
4. Click **OK**.
5. Export **Firmware Configuration Parameter** as well.
6. Save with today’s date.
