Updated Jun 30,2025

Issue description

When using xTool Apparel Printer, you may encounter a "Printer film jam" error message displayed on either xTool Creative Space (XCS) software or the LCD control panel of the printer.

  • This comprehensive guide will help you diagnose and resolve this issue efficiently.
Error Code: checkByEncoder
Error Code: filmJam2

 

Possible causes:

  • There is an actual physical jam of the film.
  • The film jam sensor inside xTool OS1 Automatic Shaker Oven Machine is dirty, triggering false readings.
  • The film roll is skewed or unevenly wound.
  • The film is not correctly aligned with the right white guide line on the processing area of the printer.
  • The printer and OS1 Oven are not assembled or connected correctly.

 

Troubleshooting

STEP1: Check for actual film jam

  • Listen for Strange Sounds:
    • An actual film jam typically produces distinctive "clicking" or "crashing" sounds from the shaker oven.
  • Use the Film Feed Function:
    • Navigate to: xTool Creative Space > Device settings > Accessory information > Film material control
    • Click the "Feed" button to force the jammed PET film out of the delivery slot.
  • Manual Removal (if needed):
    • If automatic feeding fails, allow the shaker oven to cool completely.
    • Open the maintenance door and carefully remove the jammed film by hand.

  • No Actual Jam:
    • If you determine that there is no material jam, the error may be a false alert from the device. Proceed to Step 2.

 

STEP2: Clean the film jam sensor

Tools required: Cleaning brush (Included in your package)

Sensor contamination is a common cause of false "film jam" errors.

  • Access the Sensor: 
    • Slide out the used powder bin of the oven machine to access the film jam sensor; locate the sensor as illustrated in the image below.
  • Brush the Sensor: 
    • Using a cleaning brush, gently brush away any dust or debris from the sensor.
  • Reassemble & Test:
    • Reinstall the waste powder container securely.
    • Try operating the machine again. If the error message persists, continue to the next step.

STEP3: Verify film-roll alignment

  • Check for misalignment:
    • An unevenly wound film roll or improper loading can trigger the jam sensor or cause feeding problems.
    • Visually inspect the film roll currently loaded onto the printer from the side to check for uneven winding, telescoping, or skewing.

Even Film Roll
  • If the roll appears uneven/skewed:
    • Carefully remove the film roll from the printer.
    • Place it on a clean, flat surface (e.g. a table).
    • Gently tap the ends of the roll flat against the surface to help even out the winding.
    • Reinstall and test.
  • Proper Film Alignment: 
    • When reinstalling the film holder and roll, align the film edge precisely with the white marking line.
    • The film must not overlap the white marking line.
    • The film edge must remain within ≤1 mm of the line (not shifting left or right).
  • If you cannot adjust the telescoped film roll or prefer not to attempt adjustment, please proceed to the "Still experiencing issue" section.
  • If the film roll appears to be wound correctly and loaded properly, proceed to the next step.

 

STEP4: Perform “Device self-check”

  • Restart both devices:
    • Power off the printer and oven; await 30 seconds before rebooting.
  • Run “Device self-check”:
    • On the control panel of the printer, tap Maintenance > Device self-check > Start and follow on-screen prompts.
  • If the detection test fails:
