What is samsung printer tech mode
samsung printer tech mode is a built-in service interface that provides advanced diagnostic options.

Depending on the model, it may also allow factory resets and toner warning control options.
What you can do in samsung printer tech mode
Print Usage Report (total pages and counters)
Print Supplies Report (CRUM data and toner status)
Print Event Log (error history)
Print All Reports (everything at once)
Access service functions like factory memory clear (model dependent)
Why technicians use samsung printer tech mode
If you’re troubleshooting a Samsung printer, the standard configuration report often doesn’t include firmware version, CRUM data, or deep logs. samsung printer tech mode helps you extract the exact sheet needed to diagnose:
Toner-related messages that won’t clear
Firmware version confirmation before a firmware procedure
Hidden error codes and event log history
Supplies data when a cartridge is not recognized
Counter values after maintenance or resets

Samsung SCX-3200 / 3205 / 3207 / 3200W / 3205W tech mode

Samsung SCX-3400 / 3400W / 3400F / 3400FW / 3400FH
Many SCX-3400 models share the same logic as SCX-3200 for entering samsung printer tech mode.
Common SCX-3400 entry sequence
Up → Up → Stop → Down → Down → Stop → Stop
SCX-3400F / FW / FH (menu-based method)
Some versions use:
Menu → # → 1 → 9 → 3 → 4
Then select Tech mode and go to the report section.
Samsung SCX-4600 and SCX-4623F / SCX-4623FN
These models typically use a menu/keypad pattern to access service menus.
SCX-4600 service entry
Menu → ID Copy → Left → Right → Menu → Stop
SCX-4623F service entry
Menu → # → 1 → 9 → 3 → #
Then:
Menu → # → 1 → 9 → 3 → 4 to select Tech mode
Once inside samsung printer tech mode, go to Report Configuration to print the firmware/version sheet.

Samsung SCX-4824FN / 4825FN / 4828FN / 4833FD / 4833FR
These are popular office MFP devices. Firmware version and service access often follow:
Firmware display (quick)
Menu → # → 1 → 9 → 3 → #
The display shows the firmware version on many units.
Enter samsung printer tech mode
Menu → # → 1 → 9 → 3 → 4
Then:
Tech mode → Report Configuration
If successful, the device prints a report sheet that includes firmware details.
Samsung CLP and CLX series (configuration printing)
Some models don’t expose a clean keypad service sequence, and instead rely on driver tools or “Smart Panel” utilities included with drivers.
CLP-310 / 315 / 320 / 325 series
A report can often print by holding Stop.
Otherwise, use the printer software utility to print a configuration page.
CLX-3170 / 3175 and CLX-3180 / 3185 series
A common sequence looks like:
Menu → ID Copy → Left → Right → Menu → Back → Tech Menu → Report Configuration
These sequences can vary slightly, but the goal is the same: reach Tech Menu and print Report Configuration.
Safety warnings (important)
Because samsung printer tech mode includes service options, you must be careful.
Avoid these unless you know exactly why
FC (Factory Memory Clear): Can wipe settings and cause reconfiguration headaches.
LC (Toner Low Level Control): Can alter toner warning behavior; misuse may hide real low-toner conditions.
Any “aging” or calibration items you don’t understand.
Use reports first, actions second. Reports are safe; service operations can change device behavior.
