If your fax machine is in deep sleep mode, it means that it has been idle for an extended period and has entered a power-saving state. This mode saves more power than regular sleep mode, but it may cause issues with receiving faxes. To wake your machine up from deep sleep mode, you can try any function, such as sending a fax or making a copy. If that doesn't work, you can try restarting the machine by unplugging the power for a few minutes. If your machine frequently enters deep sleep mode when you don't want it to, you can adjust the settings to increase the amount of idle time before it enters sleep mode or turn off sleep mode entirely.

How to prevent a fax machine from entering sleep mode
Sleep mode on a fax machine is an energy-saving feature that causes the machine to enter a state of low power consumption after a certain period of inactivity. While in sleep mode, the machine will not send or receive faxes until it is manually reactivated.
To prevent a fax machine from entering sleep mode, you can adjust the sleep timer settings. On many Brother fax machines, such as the IntelliFax-2840, you can access the sleep timer settings by pressing "Menu / 1 / 4 / 2". From there, you can set the length of time the machine remains idle before entering sleep mode. Setting this value to zero will prevent the machine from ever entering sleep mode. If zero is not a valid option, setting the idle time to a very high number, such as 999999999, will also effectively prevent the machine from entering sleep mode for an extended period. However, it is important to note that using sleep mode can help conserve energy, so it is recommended to set the idle time to a reasonable duration that balances energy savings with the need for the machine to remain active.
It is worth noting that some fax machines may have different methods for adjusting sleep timer settings, so it is always a good idea to refer to the specific instructions provided by the manufacturer for your particular model. Additionally, some machines may have a deep sleep mode, which saves even more power but requires physical interaction or data input to wake up and receive faxes. If you want to receive faxes at all times or use the machine as a standalone device, you may need to turn off deep sleep mode or adjust its settings accordingly.

How to wake a fax machine from deep sleep mode
A fax machine will enter regular sleep mode when it is not in use, which saves energy. The machine will wake up and receive faxes normally in this mode. However, after a certain period of time, the machine will enter "deep sleep" mode, which saves even more power than regular sleep mode.
A fax machine in deep sleep mode will only wake up and become able to receive faxes if one of the following actions is performed:
- Physically touch a key on the machine.
- Lift the handset on the machine.
- Send data to the machine from a computer or network. This will only work if the fax machine is used as a printer and is attached to a computer or network.
To prevent a fax machine from entering deep sleep mode, you can adjust the settings to increase the amount of time the machine is idle before entering sleep mode. On some Brother fax machines, this can be done by pressing Menu / 1 / 4 / 2, and then entering the desired length of time. If your machine allows it, you can set the idle time to zero to prevent it from ever entering sleep mode. Alternatively, you can set the idle time to a very high number, although the machine will eventually enter sleep mode even with a high idle time set.

How to fix a fax machine stuck in deep sleep mode
A fax machine will enter "deep sleep" mode if it has been in sleep mode for a certain period of time without receiving any jobs. Deep sleep mode saves more power than regular sleep mode. However, a fax machine in deep sleep mode will only wake up and become able to receive faxes if one physically touches a key, lifts the handset, or if it receives data from a computer or network. Therefore, if you want to use your fax machine as a standalone device or receive faxes at all times, you will need to turn off deep sleep mode.
To turn off deep sleep mode on a Brother IntelliFax-2840, you can adjust the sleep mode settings:
- Press "Menu" and choose "General Setup" => "Ecology" => "Sleep Time".
- Use the keys on the dial pad to enter the number of minutes the machine is idle before it enters Sleep Mode. You can enter anywhere from 00 to 99 minutes, or even 999999999 if you never want it to enter Sleep Mode.
- Press the "START" and "OPTIONS" keys simultaneously. The LCD will read "Sleep Mode: On."
- Press the "UP" or "DOWN ARROW" key to choose "Off".
- Press the "OK" key.
- Press the "STOP/EXIT" key.
If your fax machine is connected to a computer, you may also try uninstalling and reinstalling the MFL-Pro Suite using the "Full Driver and Software Package", which can be downloaded from the Brother website.

How to reset a fax machine
A fax machine with a "deep sleep mode" feature will enter regular sleep mode when not in use to save energy. After a certain period of time, the machine will fall into "deep sleep" mode, which saves more power than regular sleep mode. However, the machine in deep sleep mode will only wake up and become able to receive faxes if one physically touches a key, lifts the handset, or if it receive data from a computer or network.
To reset a fax machine, you can try the following steps:
- Check the phone line: Plug a classic phone into the cable used by the fax machine. Try calling yourself to determine if the issue is with the line. If you cannot make a call, fix the line by checking the cabling, telephone server, or other potential issues.
- Verify the phone cable connection: Ensure the phonecable is plugged into the correct jack. It should be connected to the LINE jack, not the speaker jack.
- Reset the fax machine to factory defaults: This will revert any changes made to the settings that may be causing issues.
- Check for enabled features: Someone may have enabled "Do Not Disturb", "Call Redirect", or other features that are interfering with incoming calls. Consult documentation or contact your phone service provider to verify and disable these features if necessary.
- Test the fax machine: Send a fax to your mobile phone or another number to see if it is dialling correctly. If it is not, there may be an issue with the fax machine itself, such as a fried fax module.
- Adjust sleep mode settings: If the issue is not related to receiving faxes, you can try adjusting the sleep mode settings to prevent the machine from entering deep sleep mode. Access the Ecology menu and set the length of time before the machine enters sleep mode to the highest possible value or zero to disable sleep mode entirely.

Power-saving settings of fax machines
Fax machines are still prevalent in many offices worldwide, despite the emergence of email and other digital communication tools. They are favoured for their ability to quickly transmit documents, as well as for the legal validity of such transmissions and the secure transmission of sensitive information.
The average power consumption of a fax machine is an important metric for businesses to consider, as it has both financial and environmental implications. A fax machine consumes power in several modes: standby, receiving, transmitting, and when printing or scanning. The power consumption of a fax machine varies depending on the model, with typical energy use ranging from 10 to 100 watts when active and 1 to 5 watts when idle.
To reduce power consumption and its associated costs, businesses can implement several strategies. One option is to use machines with Energy Star certification, which are designed to be more energy-efficient in active and standby modes. Another strategy is to invest in newer technologies that can perform similar functions as fax machines, such as digital document transfer solutions. Additionally, businesses can consider transitioning to more energy-efficient models or integrating fax capabilities into multi-function devices that serve multiple purposes while consuming less power than operating multiple single-function devices.
Fax machines often possess power-saving settings that can help reduce energy usage and costs. One such setting is the sleep mode, where the machine enters a reduced power state after a set period of inactivity. This can be customised to suit user needs, with some machines allowing users to set the length of time before the machine enters sleep mode, or even disabling it altogether. Another power-saving setting is the automatic shut-off feature, where the machine powers down completely after a set period of inactivity.
