Review on 🖨️ High-Speed Mono Laser Fax Machine, Dark/Light Gray - Brother FAX-2840 (FAX2840) by Albert Wallin

This fax machine is excellent. However, the problem of deep sleep mode is real. After pasting together a few comments that appeared on the network, I found the following. 1) The device will spontaneously enter normal sleep mode when not in use. That saves energy. In normal sleep mode, the machine wakes up from sleep mode and receives faxes normally. So that's good. 2) After a certain time (which you can set in the "Ecology" menu), the machine goes into "deep sleep" mode. This mode saves more power than normal sleep mode. However, the hibernation device will only wake up and be able to receive faxes only when: a) someone physically touches the button, b) someone picks up the phone, or c) it has received data from a computer or network. This only happens when the fax machine is used as a printer connected to a computer or network. So if you want to use it as a standalone fax machine or constantly receive faxes, deep sleep mode needs to be disabled. This is not an intuitive project. To turn off deep sleep mode, do the following: Press Menu. Use the up and down arrows to select 1. General settings and press OK. Choose 4. Ecology, press OK. Select 2nd sleep time, press OK. Then, while the screen is still showing a two-digit sleep time, press DOWN ARROW + START TOGETHER. The Deep Sleep menu is displayed. You can then use the up and down arrows to select Yes or No. Type "OK” and press "Stop/Exit” to exit manual mode. Although Deep Sleep is environmentally friendly, it remains unclear why Brother has kept access to the Deep Sleep controls so hidden and secret. great printer. As for durability and maintenance costs, it remains to be seen.
