If you reset the drum counter during the life of the drum unit currently being used, the remaining drum life will not be displayed accurately. When the Brother Printer drum error machine has printed roughly 15,000 pages, it will display a 'Replace Drum' or 'Drum Stop' notice. To maintain print quality, the drums should be replaced as a set. When replacing drums, unlike toner cartridges, the machine does not automatically recognise the change. Once the new drum is replaced, you will need to reset the drum counter on the Brother HL-L2350DW: Make sure the machine is on. Close up the front cover. Hold down the “OK” button and the “up” arrow at the same time. Press the “OK” button to select “Drum”. Select the “down” button to reset the Brother Printer drum counter.

For network-enabled HP printers, getting trapped in sleep mode is a common issue. The most common source of this problem is Windows software that manages the printer. If the Brother printer sleep mode, pressing the "Go" button will bring it back to life. Finally, in the menu window, go to 'printer' and tap 'use printer offline,' which will automatically reconnect the printer from its 'offline' status. It's a straightforward method that will switch a brother printer from offline to active status, allowing printing tasks in a queue to resume. On a Windows 10 PC, navigate to Settings > System > Power & sleep to disable sleep mode. Then, under Sleep, choose Never from the drop-down option. To resolve this issue and resume computer operation, use one of the following methods:- Press the SLEEP keyboard shortcut. Press a standard key on the keyboard. Move the mouse. Quickly press the power button on the computer. Note If you use Bluetooth devices, the keyboard may be unable to wake the system.
