Prestige R1 — Print Head Calibration (Step, Channel & Bidirectional)
Purpose
Proper calibration reduces print fuzziness, banding, and color misalignment—especially during bidirectional printing.
Step 1: Preparation & Nozzle Check Verification (00:00–01:28)
Required tools:
- Digital microscope (recommended)
- Pen
- Phone camera (acceptable alternative)
- Open DTF Station Pilot.
- Set the correct print start position.
Perform a nozzle check.
If the printer has been idle for 20+ minutes:
- Run two head cleanings consecutively before the nozzle check
Proceed only if the nozzle pattern:
- Matches or looks better than the example shown in the video
- Perform ink fills or additional head cleanings if needed.
Step 2: Bypass Cover Sensor for Calibration (01:28–01:58)
- Turn off the LED light.
Trick the cover sensor:
- Place a metal object over the sensor shown in the video
- A carriage lock or magnet may be used
- This allows calibration with the cover open.
Step 3: Step Calibration (Pinch Roller Accuracy) (01:58–03:23)
- In Pilot, open the Step Calibration sub-tab.
- Click Test Print.
The printer outputs:
- Three sets of two horizontal lines
- Each set has numeric values beneath it
Identify the set with the best overlap.
- Compare all three sets
- Use decimal values if needed
Example from video
- 0 = good overlap
- -1 = misaligned
- +1 = similar to 0
→ Enter 0.5 and click Apply
Purpose:
- Adjusts pinch roller speed
- Minimizes horizontal banding
Ideal result:
- Zero value shows strong overlap
- Adjacent values within ±1
- Run Test Print again to confirm.
Step 4: Channel Calibration – Left Direction (03:23–09:45)
⚠️ Strongly recommended to use a digital microscope
Skip this step if you do not have one and return later if print issues occur.
- Open the Channel Calibration sub-tab.
- Click Test Print.
Six nozzle bars print in this order:
- Black (reference)
- Cyan
- Magenta
- Yellow
- White
Calibration method:
- Black is the base channel
For each color:
- Compare overlap with black
- Check 0 first
- Then compare -1, +1, -2, etc.
- Choose the value with the cleanest overlap.
Adjustment rule
Step 5: Channel Calibration – Right Direction (09:45–10:15)
- Repeat the same process used for left direction.
Follow identical evaluation logic:
- Black as reference
- Select best overlap
- Apply calculated value
- Re-test after each change
Step 6: Bidirectional Calibration (10:15–11:35)
Step 7: Saving Firmware (Required if Zero Bar Is Correct) (11:35–12:38)
Enter Advanced Mode:
- Click Advance
- Password: 61 ones
- Go to the Firmware tab.
- Select Export Firmware.
Save the file:
- Store locally
- Back up to USB or cloud storage
- Press OK and exit Advanced Mode.
Step 8: Final Verification (12:38–End)
- Proceed to DigiRip.
- Run a print alignment test.
Confirm:
- Colors align cleanly
- No banding or fuzziness
If issues remain:
- Return to the appropriate calibration step
- Re-test after each adjustment
Result
Print head, color channels, and bidirectional alignment are fully calibrated for sharp, accurate, high-speed printing.
