Printer Troubleshooting

Updated 5 days ago · 7 min read

Printing is a key part of the photo booth experience for many operators. When the printer stops cooperating, it can disrupt an event or bring a pay-per-use booth to a halt. This article covers typical printer issues, their causes, and how to resolve them.

Printer Not Detected

Problem: FMX does not recognize the connected printer. The printer does not appear in the print settings, or FMX reports a printer error when trying to print.

Cause: This is usually a connection issue, a missing driver, or a conflict with other software.

Solution:

  1. Check the connection -- Verify the USB cable (or network cable, for network printers) is securely connected at both ends. Try a different USB port on the booth device.
  2. Install the correct drivers -- Make sure the manufacturer's printer drivers are installed on the booth device. Download the latest drivers from the manufacturer's website:
    • DNP -- dnpphoto.com (support/downloads section)
    • HiTi -- Check the HiTi support site for your specific model
    • Mitsubishi -- Check Mitsubishi Electric's printer support page
  3. Verify the printer appears in Windows -- Open Control Panel > Devices and Printers (or Settings > Printers & Scanners) and confirm the printer is listed and online. If it shows as offline, right-click and select Set as Online.
  4. Restart the printer and FMX -- Power off the printer, wait 10 seconds, power it back on, and then restart FMX.
  5. Check for USB power management issues -- Windows may be cutting power to the USB port. Disable USB selective suspend in Device Manager > USB Root Hub > Properties > Power Management. See Camera Troubleshooting for detailed steps.

Tip: For pay-per-use and unattended booths, a network-connected printer can be more reliable than USB, as it avoids USB power management issues entirely.

Print Quality Issues

Problem: Prints are coming out with visible artifacts -- banding, color shifts, faded areas, streaks, or spots.

Cause: Print quality problems are usually related to the print head, the media (paper and ribbon), or the printer calibration.

Solution:

  1. Clean the print head -- Most dye-sublimation printers have a cleaning procedure in their maintenance menu. Run the cleaning cycle and print a test page to check if the issue is resolved.
  2. Check the media -- Inspect the paper and ribbon for damage, wrinkles, or contamination. Make sure you are using the correct media type for your printer model. Mixing media types or using third-party supplies can cause quality problems.
  3. Check for ribbon wrinkles -- If the ribbon is wrinkled or not seated properly, remove the ribbon cartridge, inspect it, smooth out any wrinkles, and reinstall it.
  4. Calibrate the printer -- Run the printer's built-in calibration routine. This adjusts alignment and color density to match the installed media.
  5. Check the environment -- Dye-sublimation printers are sensitive to temperature and humidity. Avoid operating the printer in excessively hot, cold, or humid conditions. Keep the printer away from direct sunlight and air vents.
  6. Replace consumables -- If the print head has been heavily used, it may need replacement. Check your print count against the manufacturer's recommended head lifespan.

Paper Jams

Problem: Paper is jammed inside the printer, and the printer reports an error or stops mid-print.

Cause: Paper jams can be caused by misaligned paper, worn feed rollers, or debris inside the printer.

Solution:

  1. Follow the manufacturer's clearing procedure -- Each printer model has a specific process for clearing jams. Refer to your printer's manual for step-by-step instructions. Forcing paper out without following the correct procedure can damage the printer.
  2. Power off before clearing -- Turn off the printer before attempting to remove jammed paper. This protects both you and the print mechanism.
  3. Remove paper gently -- Pull the jammed paper slowly and evenly in the direction of the paper path. Avoid tearing the paper, as small fragments left inside can cause future jams.
  4. Inspect the paper path -- After clearing the jam, visually inspect the inside of the printer for any remaining paper fragments, dust, or debris.
  5. Check paper alignment -- When reloading paper, make sure the paper tray or feed slot is properly aligned and that the paper is seated flat without bends or curls.
  6. Check for worn feed rollers -- If jams happen frequently, the feed rollers may be worn and losing grip. Contact the manufacturer for roller replacement.

Tip: Keep a small supply of spare paper and ribbon at each booth location. Running out of supplies during an event is worse than a jam.

Slow Printing

Problem: Prints are taking much longer than expected, or there is a significant delay between the session ending and the print starting.

Cause: Slow printing is often caused by high-resolution print settings, a large print queue, or the printer's warm-up cycle.

Solution:

  1. Check print resolution settings -- Higher resolutions produce better quality but take longer. In FMX, go to Settings > Print and verify the resolution. For most photo booth applications, 300 DPI provides excellent quality with reasonable speed. Going higher (600 DPI) may not be visibly better but will double the processing and print time.
  2. Check the print queue -- If multiple sessions are waiting to print, there will be a delay. In FMX, check the queue status to see how many jobs are pending. If the queue has backed up, consider clearing stuck jobs.
  3. Allow the printer to warm up -- Dye-sublimation printers need to reach operating temperature before they can print at full speed. The first print of the day may take longer. Keep the printer powered on during operating hours to avoid repeated warm-up delays.
  4. Check the USB connection speed -- A slow USB connection can bottleneck data transfer to the printer. Use a USB 3.0 port if available and a USB 3.0-compatible cable.
  5. Reduce the print size -- Larger prints (6x8 or 8x10) take longer than smaller formats (4x6 or 2x6 strips). If speed is a priority, consider offering a smaller format.

DNP Printer-Specific Issues

DNP printers (DS-RX1, DS620, DS820) are among the most popular choices for photo booth operators. Here are DNP-specific troubleshooting tips.

DNP Printer Shows "Ribbon Error"

  • Reinsert the ribbon cartridge -- Remove the ribbon, check for wrinkles or damage, and reinstall it firmly.
  • Check ribbon compatibility -- Make sure the ribbon type matches the paper type. DNP printers require matched paper-ribbon combinations (for example, 4x6 paper must be used with 4x6 ribbon).
  • Reset the ribbon counter -- If you installed a new ribbon and the error persists, the counter may not have reset. Power cycle the printer to force a counter reset.

DNP Printer Prints with Color Banding

  • Run the cleaning routine -- Access the DNP printer utility on your computer and run the head cleaning function.
  • Check for condensation -- If the printer was recently moved from a cold environment to a warm one, condensation may form on the print head. Let the printer acclimate for at least 30 minutes before printing.
  • Update the printer firmware -- Check the DNP website for firmware updates for your specific model. Firmware updates can resolve known print quality issues.

DNP Printer Not Communicating with FMX

  • Install the DNP printer driver -- Download and install the latest driver from the DNP website. Generic Windows drivers do not work reliably with DNP printers.
  • Set as default printer -- In some FMX configurations, the printer must be set as the default Windows printer. Go to Control Panel > Devices and Printers, right-click your DNP printer, and select Set as Default Printer.
  • Check the DNP Hot Folder -- If you are using DNP's Hot Folder print method, verify that FMX is outputting files to the correct folder path.

Tip: DNP printers are designed for continuous use and are a solid choice for pay-per-use booths. Keep an extra ribbon and paper set on-site so you can swap supplies quickly without downtime.
