About the Lexmark MX826adtfe
This guide covers the Lexmark MX826adtfe, a 70 ipm monochrome laser multifunction printer listed as ENERGY STAR certified.
It uses an electrophotographic (laser/LED) imaging engine, is rated at 70 images per minute (ipm) in monochrome, and prints two-sided automatically.
Its typical electricity consumption (TEC) is 1.19 kWh per week, or about 61.9 kWh per year. It is set to enter sleep 15 minutes after the last job.

Safety information
- Plug the printer directly into a grounded wall outlet. Laser and duplicator engines draw a large current surge when the fuser or drum heats up, so do not connect them to an uninterruptible power supply (UPS), a light-duty extension cord or a power strip shared with other heavy loads.
- Keep the ventilation openings clear and leave the clearance around the unit that the manual specifies for paper trays, covers and service access.
- Switch off and unplug the unit before cleaning it or reaching deep inside to clear a jam.
- The fuser area stays very hot for several minutes after printing. Let it cool before clearing jams near the output, and follow the warning labels inside the covers.
- Do not burn toner cartridges. Wipe up spilled toner with a damp cloth; do not use a household vacuum cleaner, because fine toner dust can pass through its filter or ignite.
- Operate the printer in a well-ventilated room, especially for long print runs.
- Laser multifunction devices are heavy. Use two or more people, or the lifting equipment specified in the installation guide, and lock floor-standing casters once the unit is in place.
Setup
- Unpack and remove shipping materials
Remove all tape, foam and protective film, including pieces inside the covers and paper trays.
- Choose a location
Place the unit on a sturdy, level surface (or its floor stand) away from direct sunlight, heating vents and humid areas. Leave room to open covers and pull out trays.
- Install toner and imaging parts
Remove the toner cartridge from its bag, rock it gently side to side to distribute the toner, pull any sealing tape, and insert it until it clicks. Install the drum or imaging unit first if your model uses a separate one.
- Load paper
Fan the paper stack, adjust the tray guides to the paper size and load it below the fill line.
- Connect to your computer or network
Connect the unit to your network (Ethernet or Wi-Fi where available) or directly by USB, following the setup guide. Network connection lets several users share it and makes firmware updates easier.
- Install drivers and software
Add the printer in your operating system. Many current network printers work with driverless standards such as AirPrint, Mopria or IPP Everywhere; install the full manufacturer driver if you need finishing, security or accounting features.
- Set two-sided printing as default
Set duplex (two-sided) printing as the default in the printer driver or control panel. It halves paper use for multi-page documents.
- Check the sleep timer
The unit is shipped to enter sleep 15 minutes after the last job. Keep this setting (or shorten it) to minimize idle energy use.
Using your printer
Printing
- Leave two-sided printing on for multi-page documents; turn it off only for single sheets or heavy media that the duplexer does not support.
- Use toner-save or draft mode for internal documents.
- Select the correct paper type and size in the driver so the printer applies the right heat or ink density.
- Print jobs in batches: the first page after sleep takes a little longer while the fuser warms up.
Copying, scanning and other functions
Place originals face-down on the glass aligned with the corner marker, or face-up in the automatic document feeder (ADF) if equipped. Scan documents at 300 dpi for text and OCR, and 600 dpi for photos. Use scan-to-email or scan-to-folder destinations set up in the web interface to avoid printing copies you only need digitally.
Sleep and power settings
The factory sleep delay is 15 minutes. Use the auto-off or weekly timer (if offered) to switch the unit off overnight and on weekends.
Care and maintenance
| When | What to do |
|---|---|
| When prompted | Replace the toner cartridge, drum/imaging unit or waste-toner container; recycle used cartridges through the manufacturer's take-back program. |
| Every 3 months | Wipe the paper-feed and pickup rollers with a lint-free cloth lightly dampened with water to prevent misfeeds. |
| At the page count in the manual | Replace the maintenance kit (fuser, transfer roller, feed rollers) as specified for this model. |
| Monthly, or when copies show marks | Clean the scanner glass and (if equipped) the narrow ADF scanning strip with a soft cloth and a little glass cleaner applied to the cloth, not the glass. |
| At the scan count in the manual | Clean or replace the feed rollers and separation pad to prevent multifeeds and jams. |
| Every 6 months | Install firmware updates from the manufacturer and vacuum dust from the exterior vents. |
Troubleshooting
Most printer problems come from media, consumables, connections or settings. Try these steps first; for numbered error codes, look up the code in the manufacturer's manual or support site.
| Problem | Possible cause | What to try |
|---|---|---|
| Shows offline or jobs stay in the queue | Network or IP address changed; wrong driver or port; printer asleep and not waking. | Restart the printer and computer, print a network configuration page, re-add the printer using its current address, and reserve that address in your router. |
| Faded or uneven print | Low toner; toner-save mode on; paper type setting wrong. | Gently rock or replace the cartridge, turn off toner-save, and set the correct paper type. |
| Streaks, spots or repeating marks | Dirty or damaged drum or fuser; toner leak. | Print the cleaning page from the menu; measure the spacing of repeating marks against the manual's chart to identify the part to replace. |
| Toner smears or rubs off | Fuser not reaching temperature; heavy or coated paper set as plain. | Set the correct paper type; if smearing continues on plain paper, the fuser may need replacement. |
| Vertical lines on scans or copies | Dust or correction fluid on the scanning glass or ADF scanning strip. | Clean the glass, the narrow scanning strip and the white backing under the document feeder. |
| Multiple pages feed at once | Worn separation pad or rollers; pages stuck together. | Fan the stack before loading, clean the rollers, and replace the roller kit if multifeeds continue. |
| Paper or media jams | Wrong media for the tray; overfilled tray; worn rollers; debris in the path. | Remove jammed media in the direction of the paper path, check for torn pieces, reload within the fill line, and clean the rollers. |
| Slow to start the first job | Unit waking from sleep. | This is normal. Group jobs together; avoid disabling sleep, which raises energy use considerably. |
Energy use and running costs
The Lexmark MX826adtfe has a typical electricity consumption (TEC) of 1.19 kWh per week. ENERGY STAR's TEC test simulates a typical office week — a set number of jobs each workday, with the device dropping into sleep between jobs, overnight and over the weekend. Over 52 weeks that is about 61.9 kWh per year, roughly $10.52 a year at $0.17 per kWh.
Heavier printing volumes, disabling sleep, or a longer sleep delay than the default 15 minutes will raise real-world consumption. Paper typically has a much larger environmental footprint than the electricity, so duplex printing saves more than any power setting.
