Questions about this item

Does the SuppliesMax X644H21A-MICR cartridge run hot or draw extra power during long print runs?

Which Lexmark printer must I already own for this SuppliesMax MICR toner to work?

It fits Lexmark X642e, X642e-MFP, X644e, X644e-MFP, X644ef, X644ef-MFP, X646dte, X646dte-MFP, X646e, X646e-MFP, X646ef or X646ef-MFP models.

Will this SuppliesMax MICR toner work in an older Lexmark X642 that I still use for cheque printing?

Yes, the cartridge is listed as compatible with the Lexmark X642e and X642e-MFP, so it will function in those older devices for secure magnetic-ink output.
