Specializing in Brother products. I primarily sell multifunction devices among PC peripherals. I offer specialized maintenance that other sellers can't easily replicate, such as "replacement of the waste ink absorber pad" and "replacement of the print head," the core component. I also thoroughly clean (no ink stains) and disinfect with alcohol (COVID-19 measures) to deliver a pristine machine. Please distinguish my listings from "as-is" listings from others, which are unmaintained and uncleaned. Therefore, please refrain from requesting price reductions. My listings are not suitable for those seeking only low prices. Also, if sold on other sites, I will end the listing here without notice. ※ Please also see my profile. 【 Brother Subunit Set, Working Properly, BCL-D30K, White Type, Maintained, Cleaned, and Disinfected 】 ◉ This subunit is a very rare item even used, as it is a discontinued product by the manufacturer. ◉ It is important to check whether the model number D30 has "K" after it. The model number of this unit is BCL-D30K1, so it is compatible with all of the following main units. ★ White type, working properly, and clean. ★ This model is rare even as a used item because it is popular even after the manufacturer discontinued it. ★ You can use it comfortably as it has been cleaned and sterilized with alcohol. ★ Set includes subunit, batteries, charger, and adapter. ★ Subunits cannot be used simply by turning them on.
