Before using this Maintenance Checklist read the disclaimer near the bottom of the page

Before conducting any maintenance your printer and dryer should turned off 

• Ink Management: Check all ink levels and ensure the white ink tank is full. Thoroughly mix white ink bottles before adding them to the tank and use an ink roller for spare bottles to prevent settling.
• Inspection of Printer after start up check these areas to make sure they are clean and free from obstructions: check your capping station, wiper area, printhead area, and verify white ink circulation is working properly
• Run a Nozzle Test: Review pattern to make sure a majority of your nozzles are working properly
• Fill Hopper: Fill the hopper making sure there are no clumps in the adhesive
• Inspection of the Dryer: After turning the dryer on make sure the paddle and shaker are working properly, then open the lid of the dryer to ensure all bulbs are working properly.

Daily DTF Printer Maintenance

• Cleaning: Clean between every print run, focusing on the wiper blade, printhead surroundings, and the bottom of the carriage plate. Clean cap stations and ensure the edges are in good condition.
• Printheads: Print a nozzle test before each run and perform cleaning cycles as needed. If cleaning the nozzle plate, use a lint-free wipe with gentle pressure, wiping from the middle outward
• Environment: Protect the printer from supplemental airflow (fans/HVAC), as this can cause head failure. Keep the dryer unit clear of powder dust.  Optimal environment conditions are 72°F and 30% relative humidity.  Keep the print room at these settings 100% of the time. If the temperature in the room is over 85°F we recommend turning the printer off.

End of Day Maintenance

• Cleaning & Wet Cap:  Cleaned wiper blade, capping station, filled capping station with Capping Fluid, then Wet Capped Printheads
• Pinch Roller Maintenance: Clean the pinch rollers of the wax build up with a lint free rag.
• Adhesive Powder System: At the end of the day, empty the powder from the dryer, including the excess powder drawer at the bottom of the dryer and seal it in a 5-gallon bucket to keep it from absorbing humidity
• Dryer System: Turn Dryer off before doing maintenance - Inspect quartz bulbs, Clean with 90+ isopropyl alcohol (IPA) only when cool. Clean dryer belt with a damp rag.
