Phone Mobile Connect app and OS
The exact-model manual directs phone printing and scanning to Brother Mobile Connect. Distinguish it from desktop iPrint&Scan and the device Scan button setup.
| Check | What to check |
|---|---|
| iOS / iPadOS | Mobile Connect · App Store shows version 2.0.0 and requires iOS/iPadOS 18.0 or later. Check publisher Brother Industries, LTD. and installation conditions on the actual device. The manual’s iPhone/iPad examples do not promise installation on every older OS. |
| Android | Mobile Connect · Google Play directs users to check model support on Brother’s support site. The observed public listing did not show a minimum Android version. Check installation conditions in the official listing on the actual Android device. |
| Wi-Fi | Exact-model installation FAQ says to connect the phone by Wi-Fi to the printer’s network or use Wi-Fi Direct on supported models. Installing the app alone does not establish the connection. Compare official app connection guidance and the existing network-report guide. |
App references checked 2026-11-02. Earlier dates and scope for PC packages, interfaces, device, drum and scan diagnostics remain unchanged. For PC-only printing failure compare this DCP-L2640DW driver guide. App installation, actual connection and physical output were not tested.
Use the DCP-L2640DW specifications
The exact-model specification rows list a two-line LCD, 50-sheet ADF, automatic duplex printing, USB 2.0, 10/100 Ethernet, wireless LAN and Wi-Fi Direct. Use a USB cable no longer than 2 m; third-party USB hubs are unsupported. The shared manual covers several models, so select the DCP-L2640DW group rather than touchscreen or fax-only instructions.
Windows drivers and Mac AirPrint have different roles
On 2026-10-11, the Windows 11 download list separates EasySetup for initial setup, Full Driver & Software Package after initial machine setup, Printer Driver, Printer Driver & Scanner Driver for USB, and Brother iPrint&Scan. Choose the component for your connection and task; firmware is a separate update.
The macOS 26.x page recommends AirPrint under Printer Driver Information and lists scanning software separately. The manual states that Mac printer drivers are not provided. A Mac software package is not a dedicated printer driver. For a different OS, change the model's OS selection and check the current package requirements.
Set up the machine Scan button
Verified 2026-10-18: the US Version C guide separates PC-started scanning from the physical Scan button. In Brother iPrint&Scan, use Select your Machine for this unit and Machine Scan Settings for button settings. File type and save location are configured in the app. Official button settings
- Open iPrint&Scan on the destination computer and confirm DCP-L2640DW is selected.
- Load the original, press the physical Scan key, select to PC and confirm with OK, then choose Image and OK.
- For a network connection, select the destination computer and confirm with OK. Enter its configured four-digit PIN only if prompted.
- Use Options or Copy/Scan Options for this job if needed, then press Start. With the scanner glass, follow the LCD prompts to finish.
These are the DCP-L2640DW physical-button Image steps; the installed, connected iPrint&Scan computer is required for changing scan settings. Exact model group in the guide
When PC scanning works but the button fails
| Workflow | Check |
|---|---|
| PC app first | Select the actual machine in iPrint&Scan and compare a scan started from the computer with the button workflow. The app then offers save/share, file name and file type settings. PC scan workflow |
| Windows button | The model FAQ names Brother iPrint&Scan.exe and iPSNotifier.exe for permitted application communication. Check the approved app permissions with the administrator. Network-scan FAQ |
| Mac button | The FAQ requires the separate iPrint&Scan Push Scan Tool plus button configuration in iPrint&Scan. On macOS 15 or later, also check the app’s Local Network permission. Use the model download selector for the installed OS. Model downloads |
The FAQ is dated 2026-08-18. AirPrint printing does not establish button-scan setup; Linux Scan-key-tool remains a separate workflow below. These source steps do not verify the installed app version, package CPU or physical scanning.

Linux printer driver downloads: choose the DEB component by task
Checked 2026-11-09 on the exact DCP-L2640DW Linux (deb) list Use the component names below to find the files in Brother's list.
| Component | Observed version / date / size | Purpose |
|---|---|---|
| Driver Install Tool | 2.2.6-1 · 2026-10-22 0.02 MB | Installs LPR/CUPSwrapper and a scanner driver where applicable. Its tool version and small size do not identify every downloaded component or a complete offline bundle. |
| Linux printer driver | 4.1.0-1 · 30 May 2023 0.09 MB | The exact model’s DEB printing package; an installed print queue does not establish scanning. |
| Scanner driver | 1.8.1-0 32bit · 2026-10-28 · 0.85 MB 64bit · 2026-10-29 · 0.83 MB | Scanning component. Select the matching listed package rather than substituting the print driver. |
| Scan-key-tool | 32bit · 0.05 MB / 64bit · 0.06 MB 0.3.6-0 · 2026-10-23 | Supports starting a scan with the machine’s button. This is a separate task from computer-initiated scanning. |
| Scanner Setting file | 1.0.2-0 · 25 November 2016 1.52 KB | For USB scanner access without administrator privileges. It is a permission-related setting package, not a network or print-driver repair. |
The table reflects Brother US support's Linux (deb) listing. Match the package to your distribution and CPU; a 32bit or 64bit label alone does not establish ARM or Raspberry Pi compatibility.
If printing works, troubleshoot computer scanning and the printer's scan button separately.
DCP-L2640DW not printing: compare device and computer output
Run the two-line LCD test print
Load paper, press Menu, select Printer with the arrow buttons and press OK. Select Print Options → OK, then Test Print → OK, and press Start. Finish with Stop/Exit (DCP-L2640DW test-print steps). If this device output fails, check its display and paper path first. If it works, compare the computer connection and software.
Slow printing: check Quiet Mode
Verified 19 October 2026: Quiet Mode only.
The Version C guide says Quiet Mode reduces printing noise and slows printing when enabled. Its factory setting is Off; that does not establish your current setting. Use the DCP-L2640DW physical-button group, rather than the touchscreen instructions for other models.
Press Menu. Use the arrow keys to select General Setup, Ecology, then Quiet Mode, confirming each with OK. Choose On or Off as needed, confirm with OK, then press Stop/Exit.
Common check: compare the actual setting, a device Test Print and the same host job before attributing slowness to the driver. A job that never prints needs separate connection and queue checks.
Exact-model Quiet Mode instructions · Compare device Test Print · DCP-L2640DW driver checks
Toner Save: compare lighter output with the actual setting
Toner Save may reduce toner consumption, and documents print lighter when it is On. Brother does not recommend it for photos or grayscale images. Use the DCP-L2640DW physical-button group in the Version C guide.
- Open Menu.
- Use the up/down keys to select General Setup; confirm with OK.
- Select Ecology with up/down, then OK.
- Select Toner Save with up/down, then OK.
- Choose On or Off as needed using up/down and confirm with OK.
- Leave the menu with Stop/Exit.
If the entire page is too light, the quality guide says to check Toner Save in the machine menu or printer driver and turn it off. Record your existing setting and compare the same document; lighter output alone does not identify an empty cartridge or driver failure.
These steps do not establish your current setting or a toner-saving percentage. The touchscreen sequence for other models is separate. Existing Quiet Mode guidance concerns printing noise and speed.

Read the current address from the network report
Press Menu → Print Reports → OK → Network Config → OK → Start. The report lists IP and other network settings. If the address is 0.0.0.0, wait one minute and print it again. Compare the current IP with the computer's selected network printer port; this comparison is a common PC check.
ADF document jams: removal direction depends on location
The US Version C guide lists DCP-L2640DW in these three document-jam procedures. Identify the location and its drawing; ADF originals use a different path from printer-tray or duplex paper jams.
Original jammed at the top ADF
- Take the unjammed originals out of the ADF.
- Open the top ADF cover.
- Draw the jammed original out to the left; remove torn fragments too.
- Shut the ADF cover.
- Press Stop/Exit on DCP-L2640DW.
Original under the document cover
- Remove originals that are not jammed from the ADF.
- Lift the flatbed document cover.
- Draw the jammed original out to the right and remove any torn pieces.
- Shut the document cover.
- Press Stop/Exit.
Small scraps left in the ADF
- Lift the document cover.
- Follow the first illustration labelled DCP-L2640DW: insert stiff paper, such as cardstock, into the ADF to push small scraps through.
- Shut the document cover.
- Press Stop/Exit.
The scrap-removal page has two drawings. DCP-L2640DW belongs to the first model group; use that drawing rather than the second MFC-L2900DW-family drawing. Of the shared Stop/Exit or X controls, this model uses its physical Stop/Exit key.
| Case | Next check |
|---|---|
| ADF jam | Choose the cover and left/right removal direction for its location. Guide → |
| Feeds but scans have lines | Use the existing flatbed / ADF copy comparison and glass checks. Guide → |

Device Scan-button checks · Printer paper jams / LCD messages
Verified 22 October 2026 against the three document-jam topics and index explicitly listing this model. The earlier scanner-cleaner discrepancy remains unresolved; software, connection and corona-wire evidence keeps its earlier dates.
Vertical lines on copies or scans: compare three paths
Brother FAQ 153039 includes DCP-L2640DW and compares these outputs before cleaning. A small ink or correction-fluid spot on the ADF glass can create a line.
| Result | Next check |
|---|---|
| Test Print has lines | Follow the existing print-quality / corona-wire checks. This is not isolated to scanning. |
| Test Print clean; flatbed copy has lines | Inspect the broad scanner glass and white backing. |
| Flatbed copy clean; ADF copy has lines | Inspect the narrow ADF glass strip and white bar. Reinstalling the print driver does not remove dirt. |
Before cleaning: official instructions differ
The instructions differ: Version C scanner care specifies a water-dampened soft lint-free cloth; its parent precautions specify dry cloths and prohibit sprays and alcohol/ammonia solvents. US FAQ 153039 instead names alcohol/glass cleaner and says water is ineffective. Confirm the suitable method with Brother before using a cleaner; do not transfer the FAQ solvent advice to the panel or printer interior.
- The Version C scanner page starts by holding the power button to switch off, then opening the document cover.
- Its diagrams distinguish the broad glass/white plastic from the ADF strip/white bar. The extra rear-glass step is conditional on automatic 2-sided scanning; do not assume every shared-manual model has it.
- After the documented cleaning, close the cover, switch on and compare copies again. Persistent lines need Brother support.

Drum ! / vertical lines: clean the corona wire and return the tab
For print-quality problems or Drum !, follow the exact model’s corona-wire procedure. Cleaning does not establish that every drum-related fault has the same cause.
- Open the front cover and take out the toner cartridge/drum assembly.
- Gently slide the green tab left and right several times.
- Return the tab to Home: align its arrow with the drum-unit arrow. Leaving it elsewhere can cause a vertical stripe.
- Put the assembly back and close the front cover.
Follow the linked cleaning precautions: use a dry lint-free cloth, and keep sprays, flammables and alcohol/ammonia cleaners away. Do not touch the surfaces marked in the manufacturer’s diagrams.
If Drum ! remains, the exact FAQ also checks assembly seating and then drum life. For persistent black lines, the separate FAQ lists scanner glass, toner/drum damage and possible fuser contamination requiring Brother support; do not keep reinstalling drivers as the only fix.

94mm repeating marks: print the drum check sheet
The interval suggests possible drum contamination; it does not prove failure or require replacement. Use the DCP-L2640DW two-line LCD route.
- In Ready mode, press Menu.
- Select Print Reports with ▲/▼; press OK.
- Select Drum Dot Print; press OK.
- Press Start to print the check sheet, then Stop/Exit.

Drum-life messages and resetting the counter after replacement
The toner cartridge and drum unit are separate supplies. Identify the displayed message first.
| Display message | First action |
|---|---|
| Drum ! | The corona wire needs cleaning. Use the existing cleaning procedure. |
| Drum End Soon | The drum is nearing the end of its life. Prepare a new drum before Replace Drum appears. |
| Replace Drum | The drum needs replacement. Fit a new drum, then follow the counter procedure below. |
Reset the drum counter only when replacing the drum with a new one. Do not use this after cleaning the corona wire or changing only the toner. Complete the illustrated drum replacement procedure first.
- After fitting a new drum, make sure the machine is turned on.
- Make sure the machine cover is closed.
- Press OK and ▲ (Up) at the same time.
- Press OK to select Drum.
- Press ▲ to reset the drum counter.
This is the physical-button group that explicitly includes DCP-L2640DW. Other models in the same guide use touchscreen Toner/Yes controls. Resetting a counter does not restore wear on an old drum.
For 94mm repeating marks, compare the existing drum check sheet; for a common PC-side comparison, use the device test and check this model’s drivers and queue when only PC jobs fail. A drum-life message needs the supply check above.
Official counter reset: DCP-L2640DW physical-button group · Official error and maintenance messages
Checked 27 October 2026 against the exact-model group and ▲ illustrations in the US Online User’s Guide Version C. Earlier driver, scan and cleaning evidence keeps its original date. No physical replacement, counter reset or printing was tested.
DCP-L2640DW paper and duplex messages
If one-sided jobs print but automatic duplex stops, start with the LCD message. A duplex size mismatch and a cover or tray problem call for different checks.
- Size Error DX
- Choose a size that supports automatic duplex and match the loaded paper, the tray setting and the print job. The DCP-L2640DW group in the U.S. manual lists Letter, Legal, Mexico Legal, India Legal and Folio. The shared FAQ also lists A4 and says supported sizes vary by region. Follow the manual for your region.
- 2-sided Disabled
- Close the rear cover until it latches and seat the duplex tray fully. If paper is caught, see the Jam 2-sided procedure.
- Size Mismatch / Media Mismatch
- For Size Mismatch, compare the loaded sheet size with the machine’s tray size setting. For Media Mismatch, match the job’s media type, the machine’s Paper Type and the paper in the tray.
- Manual Feed
- Load the slot if you intended to feed manually. To use the regular tray on Windows, cancel the job, choose Auto Select for Paper Source in Printing Preferences and print again. If the setting is missing, see the DCP-L2640DW driver guide.

When the DCP-L2640DW shows Cannot Detect or No Toner
If Cannot Detect appears, read the message that scrolls after it. The display can point to either the toner cartridge or the drum unit.
- Cannot Detect. Reseat the toner and drum as described below. If the message remains, identify the part named in the scrolling message. Brother directs you to replace the toner cartridge if it names toner, or the drum unit if it names the drum.
- No Toner or Cartridge Error. Check how the cartridge sits in the drum and how the assembly sits in the printer. If No Toner remains after reseating, try a new toner cartridge. If Cartridge Error remains, contact Brother support.
- Wrong Toner. Check the supply number for the region where the printer was sold. Brother’s U.S. listing names the TN830 family for toner and DR830 for the drum. For a printer bought elsewhere, use its regional DCP-L2640DW supplies list.
To reseat the assembly, open the front cover and pull out the toner and drum together. Press the green lock lever to release the cartridge, then seat it in the drum until it locks. Put the assembly back and close the cover. If you installed a new drum, see the drum counter instructions.
If the display clears and the printer’s own test page works but computer jobs still fail, check the print queue and connection in the DCP-L2640DW driver guide.

Nine displayed messages: follow the model's group
The two-line LCD error table uses Manual Feed and Media Mismatch; touchscreen variants have different wording. These are selected messages, not the complete error list.
| Message or symptom | First check | Help |
|---|---|---|
| Toner Low / Replace Toner | Toner Low still permits printing; prepare a replacement. Replace Toner stops printing and requires a new cartridge. | Toner messages |
| Drum ! | Clean the corona wire with the green tab, then return it to its Home position. | Corona-wire procedure |
| Jam Tray 1 | Pull the tray out and gently remove the trapped paper; refit the tray. | Tray procedure |
| Jam Inside | Keep power on for 10 minutes to cool the interior, then follow the front-cover/cartridge procedure. | Inside-jam procedure |
| Jam Rear | Keep power on for 10 minutes to cool the interior, then follow the rear/fuser-cover procedure. | Rear-jam procedure |
| Jam 2-sided | Keep power on for 10 minutes, then inspect the paper and duplex trays using the illustrated procedure. | Duplex-tray procedure |
| Manual Feed | The driver selects Manual but the slot is empty. Load it or correct the paper-source setting. | This model driver/settings guide |
| Media Mismatch | Match the driver media type, machine Paper Type setting and loaded paper. | This model driver/settings guide |
| Device test works; computer job fails | Common checks: selected model, connection/port, paused queue and OS package. For scan-only failure, check the scanning component. | This model driver guide |
Manual Feed and Media Mismatch are setting-related causes in the official table; reinstalling software is not the first remedy. Internal parts can be hot: use the cooling and illustrated jam procedures above. The drum counter is reset only when replacing the drum with a new one; cleaning the wire does not justify resetting it. Contact Brother support if the prescribed procedure fails.
Linux prints, but scanning or the machine’s scan button fails
- Separate the failing task: printing, a scan started on the computer, or a scan started with the machine’s button. For a package mismatch compare this exact printer driver download guide with the DEB component table. A working print queue is not a scanner test.
- For computer scanning, check the selected 32bit/64bit scanner package and the distribution’s requirements. The exact scanner detail includes DCP-L2640DW among compatible models; that does not guarantee every Linux release or ARM CPU.
- For the button workflow, check the separately installed Scan-key-tool and whether its brscan-skey process is running. Brother’s 26 July 2022 Scan Key Tool FAQ describes brscan under the user’s home directory as the output location; confirm the actual destination and user session before assuming a scan is missing. Its old developer script examples are not a current-version installation recipe.
- If USB scanning fails only for an ordinary user, review the USB Scanner Setting file purpose separately. Keep the existing cable and network checks; a USB permission package does not repair a Wi-Fi address. Avoid treating permanent administrator execution or disabling a firewall as the general solution.
When installation is needed, follow the exact package’s distribution requirements and official instructions. If the printer displays a device error, use the existing message checks above first.
