Operating Instructions
General Printing Process (DTG/DTF)
- Prepare the Garment/Film:
- For DTG printing on 100% cotton T-shirts, place the garment flat on the garment tray.
- For DTF printing, prepare your DTF film.
- Load the Tray: Carefully slide the garment tray or film into the printer.
- Software Settings: Open the AcroRIP White ver10.3 software.
- Select the appropriate print mode (DTG or DTF) and color configuration (CMYK LC LM or CMYK+2W).
- Adjust print resolution to 1440x1440 dpi for optimal quality.
- Ensure the design fits within the maximum effective printing area (297mm x 420mm).
- Start Printing: Initiate the print job from the software. The printer will automatically feed the tray and begin printing.

- Post-Printing (DTF Specific):
- After printing on DTF film, apply DTF powder evenly over the wet ink.
- Cure the film in an oven or heat press according to DTF powder instructions.
- Once cured, the design can be transferred to the garment using a heat press.
- Heat Press Application (DTG/DTF):
- Place the printed garment (DTG) or the cured DTF film on the garment (DTF) onto a heat press.
- Apply heat and pressure as per ink/film manufacturer's recommendations.
- Carefully peel off the film (for DTF) after pressing.
Intelligent Features
- White Ink Stirring: The printer features intelligent white ink stirring to prevent pigment settling, which is crucial for consistent white ink performance and preventing clogs. This system operates automatically.
- Efficient Printing: The L805 printer is designed for efficiency, eliminating the need for cumbersome reset operations often found in older models like L1800/1390.

Maintenance
Regular maintenance is essential to ensure the longevity and optimal performance of your Sihao A3 DTG L805 printer.
Daily Maintenance
- Nozzle Check: Perform a nozzle check daily to ensure all nozzles are firing correctly. If any nozzles are missing or clogged, perform a head cleaning cycle.
- Wipe Print Head: Gently wipe the bottom of the print head with a lint-free cloth moistened with cleaning solution to remove any excess ink.
- White Ink Stirring: Confirm the automatic white ink stirring mechanism is active and functioning.
Weekly Maintenance
- Cleaning Station: Clean the capping station, wiper blade, and surrounding areas with a cleaning solution and cotton swabs. Remove any dried ink or debris.
- Ink Levels: Check ink levels and refill as necessary to prevent air from entering the ink lines.
Long-Term Storage
- If the printer will not be used for an extended period, perform a thorough cleaning cycle and ensure the print head is capped to prevent drying.
- Store the printer in a clean, dry environment within the recommended temperature range.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Poor print quality / Missing lines | Clogged nozzles, low ink levels, incorrect software settings. | Perform a nozzle check and head cleaning. Check ink levels and refill if necessary. Verify print settings in AcroRIP. |
| Printer not responding | Loose USB connection, power issue, software not running. | Check USB cable connection. Ensure printer is powered on. Restart printing software and computer. Verify software lock (dongle) is inserted. |
| White ink settling/clogging | White ink not stirred sufficiently. | Ensure the intelligent white ink stirring mechanism is active. If manual stirring is possible, perform it. Perform head cleaning. |
| Colors are inaccurate | Incorrect color profile, wrong ink type, print head issues. | Verify color profiles in AcroRIP. Ensure correct ink types are used (DTG for cotton, DTF for other fabrics). Perform nozzle check and head cleaning. |
