打印机加完粉后必须清零

After the printer is refilled with toner, it must be reset to ensure proper functioning of the machine. To reset the printer, you must turn it off and back on. When the printer is turned back on, it should automatically reset itself. If it does not reset itself, then you must manually reset it by pressing and holding the Reset button for a few seconds. Once the printer is reset, it should be ready to go and you can start printing again.
