Long holidays are a well deserved break for your team, but they can be a risky period for your printing equipment. Without proper shutdown care, your Fedar sublimation printer or Fedar textile printer may suffer from clogged printheads, ink system issues, mechanical corrosion, or moisture damage. These problems lead to delayed production, costly repairs, and unnecessary downtime. Follow this complete holiday maintenance guide to ensure your machines start smoothly when you return.
1. Pre Shutdown Printhead Check Before any shutdown, print a nozzle test pattern. Carefully inspect the test print to confirm all nozzles are firing correctly – no missing lines, no deflection, no blur. This step ensures that you are not leaving a hidden problem that could worsen during the idle period. Only proceed with shutdown when the printhead is in perfect condition.
2. Secure the Ink Supply System
Check all connectors from the main ink tank to the secondary ink cartridge. Tighten every clip to ensure they are fully locked and have no looseness. This prevents ink leakage during the holiday, protecting internal components from ink corrosion and avoiding ink waste.
3. Regular Nozzle Maintenance During Longer Breaks
If possible, arrange for someone to print a nozzle test every 3 days during the holiday. If any clogging is detected, run a cleaning cycle immediately. Keeping the printhead active prevents ink from drying inside the nozzles, making post holiday start up much easier.
4. Proper Printhead Sealing (Depending on Shutdown Length)
Shutdown ≤ 7 days: Simply close the printhead capping station (seal the head).
Shutdown > 7 days: First perform an ink charging operation to fill the ink cap with ink. Then clamp the waste ink tube before sealing the printhead.
Important: Never use alcohol or cleaning solution for this sealing procedure. Those liquids evaporate too quickly, accelerating ink drying and causing severe clogs or damage to the delicate printhead.
5. Final Shutdown Check
Before turning off the power, verify that the printhead is fully seated against the capping station – the seal must be airtight. This is the most critical step to keep the printhead moist and prevent ink from drying. It greatly extends printhead life and reduces troubleshooting time after the holiday.
6. Cleaning and Nozzle Check Intervals
Do not leave more than 15 days between a printhead cleaning operation and a nozzle check. If the interval exceeds 15 days, ink may solidify inside the nozzles, leading to permanent clogs and potentially ruining the printhead.
7. Maintenance for Printers with a Humidifier Tray (Moisture Pad)
For Fedar models equipped with a humidifier (moisture pad) structure, perform extra care:
Thoroughly clean any residual ink from the moisture pad.
Add distilled water to the pad until the liquid level reaches at least 1/3 of the pad depth.
Inspect the printhead inlet valve to ensure it is tightly clamped to the ink tube, preventing air leaks.
Finally, seal the printhead properly to provide full humidity protection.
8. Strict Environmental Control
The room where your Fedar sublimation printer or textile printer is stored must maintain:
Temperature: 18°C – 30°C (64°F – 86°F)
Relative Humidity: 35% – 65%
Low temperatures can damage precision components and alter ink properties. High or low humidity affects ink flow and drying behavior. Keep the environment stable to avoid unexpected failures.
9. Physical Security and Dust Protection
When the workshop is unattended:
Cover the printer with a dust cover to prevent dust from settling on printheads, ink lines, and mechanical parts.
Fire prevention: Remove flammable materials from the printer area.
Water leakage prevention: Check nearby pipes.
Anti-rodent and anti-insect: Clean up any food residue or debris that could attract pests.
Security: Ensure the workshop is locked and monitored.
By following these nine steps, your Fedar sublimation printer and Fedar textile printer will remain in peak condition throughout the holiday. When you return, you can simply remove the dust cover, run a quick nozzle check, and resume high efficiency production without unexpected “strike”.
