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 sanitize with alcohol (COVID-19 measures) to deliver a pristine machine. Please distinguish my listings from "as-is" listings from others, which are not maintained or cleaned. 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 may end the listing here without notice. ※ Please also see my profile. 【 Brother Subunit Set - Fully Functional BCL-D30K Silver Type - Serviced, Cleaned, and Disinfected 】 ◉ This subunit is a discontinued product by the manufacturer, making it a rare item even in the used market. ◉ The presence of "K" after "D30" in the model number is crucial for this subunit. This unit's model number is BCL-D30KB, making it compatible with all the following main units. ★ Silver type, fully functional, and in good condition. ★ This model is popular even after the manufacturer discontinued it, making used items rare. ★ Alcohol cleaned and sterilized, so you can use it with peace of mind. ★ Set includes the subunit, batteries, charger, and adapter. ★ Subunits cannot be used simply by turning them on. You need to perform setup with the main unit, so I've included a setup guide for all main units (photo 1). ★ Compatible main units include the MFC630 series, MFC-650 series, MFC-850 series, MFC-860 series, MFC-870 series, and MFC-880 series multifunction devices, and the FAX-310 series, FAX-315 series, and FAX-360 series fax machines. This product is compatible with all of these. ★ Shipped via Letter Pack Plus.
