What You'll Learn
Sleep mode conserves energy
When a fax machine says "sleep", it means that it has entered a power-saving mode. This is also known as sleep mode or standby. In this mode, the machine consumes less energy but should still be able to receive faxes without error. You can change this setting by going into the options menu and turning off sleep mode.
Sleep mode is a feature on many electronic devices, such as computers and fax machines, that helps to conserve energy when the device is not in use. In sleep mode, the device enters a low-power state where it consumes significantly less power compared to when it is fully active. This can be useful for saving energy and reducing power consumption, which can also help reduce electricity costs.
For example, on a computer, sleep mode will keep the RAM powered but suspend most other activities, allowing the computer to quickly resume full functionality when needed. This can be useful if you are stepping away from your computer for a short break but want to be able to quickly pick up where you left off.
To further minimize power consumption in sleep mode, you can take a few additional steps. These include ensuring that your device's power management settings are configured appropriately, disconnecting any unnecessary peripherals that may draw power even when the device is asleep, and keeping your operating system and drivers up to date.
It is worth noting that, while sleep mode does conserve energy, there are other modes that may provide even greater energy savings. For example, on a computer, hibernate mode uses slightly less energy than sleep mode as it shuts down the RAM in addition to other power-hungry parts of the computer. However, the trade-off is that it takes longer to resume from hibernation mode compared to sleep mode.

The fax machine should wake up automatically when in use
Sleep mode on a fax machine indicates that the device has entered a low-power state, conserving energy. This mode is usually activated automatically when the machine is idle for a certain period, with some machines differentiating between regular and deep sleep modes. While in sleep mode, the fax machine should still be able to receive faxes without error.
If the fax machine does not wake up automatically when in use, there are several steps you can take to rectify the issue. Firstly, you can try restarting the machine by unplugging the power for five to ten minutes and then plugging it back in. If this does not work, you may need to perform a more involved reset process. For some machines, this involves pressing a specific sequence of buttons or keys. For example, on some Brother machines, you can reset the sleep mode settings by pressing Menu/Set, 1, 6, 2. On other machines, you may need to reset the machine by pulling out the plug, holding down the menu key while plugging it back in, and then entering specific codes when maintenance mode appears on the display.
If the machine still does not wake up automatically, you may need to adjust the sleep timer settings. On some machines, this can be done by pressing Menu / 1 / 4 / 2, which allows you to set the length of idle time before the machine enters sleep mode. You can set this to zero to prevent the machine from ever entering sleep mode, or to the highest possible value to delay it as much as possible.
In some cases, the issue may be caused by the phone line connection or certain telephone line services that block incoming faxes. Therefore, it is recommended to check your connection and ensure that no call-blocking services are enabled. Additionally, upgrading the printer firmware may help resolve the issue, as some machines may not wake up from sleep mode due to outdated firmware.
If none of these solutions work, it may be time to consider purchasing a new fax machine, especially if your current machine is older than three to five years, which is the typical lifespan of these devices.

If the machine doesn't wake up, reset it
If your fax machine is in sleep mode, it means that it has entered a power-saving mode. The machine should still be able to receive faxes without error. However, if you want to send a fax, you will need to wake the machine from sleep mode.
To do this, you can change the sleep timer settings. On some machines, you can press Menu / 1 / 4 / 2 and then enter the length of time the machine is idle before going into sleep mode. You can set this to zero to prevent the machine from ever entering sleep mode. Alternatively, you can set the timer to a high number, such as 999999999, to delay the machine from entering sleep mode.
If your fax machine doesn't wake up from sleep mode, you may need to reset it. Here are some general steps to reset a fax machine:
- Unplug the power cord from the machine.
- Press and hold the "Menu" button on the machine.
- While holding the "Menu" button, plug the power cord back into the machine.
- Continue holding the "Menu" button until you see a "Maintenance" or Reset" option on the display.
- Enter the code provided by the manufacturer to initiate the reset process. It is important to refer to the manufacturer's instructions or a technical support specialist to ensure you are using the correct code.
If the machine still doesn't wake up after resetting, there may be another issue with the machine or the phone line connection. You can try calling the fax number from your phone to see if there is any response. If there is no response, you may need to check the phone cable connections and ensure the line is working properly. You can also try plugging in a classic phone to test if the line is working. If the line is functional, the issue may lie with the fax machine itself, and you may need to consult a technician for further troubleshooting or repair.

The machine may need to be replaced
If your fax machine is in sleep mode, it means that it has entered a power-saving mode. This is a normal feature of fax machines, and they should wake up automatically when you try to use them. However, if your fax machine is non-responsive, you may need to try some troubleshooting methods.
Firstly, check if your fax machine is in the correct receive mode. Each time you press the MODE key, it will change the receive mode. Ensure that the machine is set to the correct mode for your setup, whether that be fax only, fax/telephone, TAD mode for an answering machine, or another mode.
If your fax machine is still not responding, you can try restarting the machine by unplugging it for five to ten minutes and then plugging it back in. If this does not work, you may need to reset the machine. For some machines, this can be done by pulling out the plug, holding down the menu key while plugging the machine back in, and then entering specific codes when maintenance mode appears on the display. However, this process will differ depending on your machine, so be sure to consult your user manual or manufacturer guidelines.
If your fax machine still does not respond after trying these troubleshooting methods, it may be beyond repair. Fax machines typically have a lifespan of around three to five years, and if yours is beyond this age, it may be time to replace it.
