Home › DTF › When and How to Replace a DTF Printer Wiper Blade
Short answer: The wiper blade scrapes ink off the printhead after cleanings. Replace it when the edge is nicked, hardened or caked with dried ink, or when nozzle checks get worse right after cleaning. Most wipers pop out of their holder and the new one presses in — a few minutes’ job.
Signs of a worn wiper
- Nozzle check worse after a cleaning.
- Ink smears or streaks across the print.
- Visible nicks, curling or hard dried ink on the blade.
How to replace
- Power off and move the carriage away from the wiper (follow your printer’s maintenance mode).
- Lift the old blade out of its holder.
- Clean the holder with flushing solution and a foam swab.
- Press in the new blade, flat and straight.
- Run a cleaning and a nozzle check.
Wipe the blade daily as part of your maintenance routine.
