How to set scan resolution and color depth on Samsung
By Sai Kiran Pandrala · reviewed by Sai Kiran Pandrala, Editor Last verified: 2026-05-30
What this guide covers
Configure this scan-to-X workflow on your Samsung printer.
Step-by-step
- On the panel or app, navigate to Scan → Resolution.
- Standard text: 300 dpi.
- Photo with text: 600 dpi.
- Archival / high-quality photo: 1200 dpi.
- Colour: choose Colour / Grayscale / Black-and-white depending on document.
- Higher resolution = larger file size and slower scan; pick the lowest that's good enough.
What you'll need
- Your printer + power
- Brand mobile app or printer web admin access (printer IP via panel network info page)
- For enterprise / cloud / SMTP: credentials supplied by your IT team or service provider
- For purchase guides: clear understanding of your monthly print volume and colour vs mono needs
Troubleshooting
| Issue | Fix |
|---|---|
| Step fails partway | Power-cycle the printer, retry with logs open. |
| Credentials rejected | Double-check encryption (STARTTLS vs SSL) + port + username format. |
| Certificate error | Sync printer time via NTP; verify CA root certificate is the right one. |
| Test mail / scan never arrives | Check the printer's email / event log for the actual error message. |
Frequently asked questions
Does this guide apply to my specific model?
The procedure is the standard one for the brand. Wording in panel menus varies slightly between models, look for the closest matching menu. Vendor support sites have model-specific articles.
Is the configuration retained after a firmware update?
Usually yes, but enterprise WiFi credentials sometimes get cleared. Document your settings before any update.
Can I script this for a fleet of printers?
Most brands expose a SOAP or REST API on the embedded web server. Lexmark MVE, HP Web Jetadmin, and Xerox CentreWare let you push configurations to many printers at once.
Where do I see the brand's authoritative procedure?
The brand support site indexed for your exact model. Wording in panel menus varies between models.

Why this matters for your day-to-day
this unit that's misbehaving costs more than the fix itself: lost productivity, missed calls, security risk, even safety risk in some categories. Treating the symptom quickly with a documented procedure is cheaper than letting it persist. The steps above are written to get you back to working in under an hour where possible, and to flag clearly when escalation is the right call.
Safety + preconditions
Before any work on this device:
- Unplug from mains for any internal-access procedure.
- Discharge stored energy (capacitors in PSUs, residual battery charge) per manufacturer guidance.
- Use ESD-safe handling for boards and modules: no carpet, no wool sleeves.
- Avoid moisture; never apply liquids near vents or connectors.
- If you smell smoke, see scorch marks, or feel uneven heat, stop and escalate.
Verification checklist
After applying the fix on the device, confirm:
- The original symptom is no longer reproducible.
- Related features (status LEDs, app sync, paired accessories) still work.
- The device responds to a soft reboot without the fault returning.
- Any error codes that were on display have cleared.
- Documentation (your service log, the brand companion app) reflects the change.
Escalation guide
For this hardware, the right escalation depends on impact:
- Cosmetic / minor: log a ticket via the How app or web portal. Response 1-3 business days.
- Mid-impact: phone support. Have your serial number ready.
- Critical (production down, safety issue): in-person dealer / TAC visit. Bring proof of purchase.
- Out of warranty: third-party repair shop with manufacturer-certified technicians.
More frequently asked questions
Should I update firmware first or last?
Update firmware first if a release note specifically mentions your symptom. Otherwise, finish the troubleshooting flow first, then update; that way you can isolate whether the update or the underlying fix solved it.
Will the procedure work on the international variant?
Some features and firmware paths are region-locked. Check the model spec sheet to confirm your variant supports the menu option referenced. If you're outside the US/EU, look for the regional support portal.
How long does this fix usually take?
Most users complete the steps in 20-45 minutes the first time, and 5-10 minutes on subsequent runs once the menu paths are familiar.
Are there safer alternatives for non-technical users?
Yes, the manufacturer's self-service troubleshooter (HP Smart, LG ThinQ, Samsung Members, similar) usually walks through the same steps in a guided UI. Use that first if you're not comfortable with menu paths.
Does this affect other devices on my network?
Generally no. The procedure is local to this device. Network-side changes (firmware updates that affect TLS, SMB, or routing) are flagged explicitly in the steps.
Topology and where scan resolution and colour depth actually breaks
Samsung multifunction units talk to three things at once when you press Scan: the device firmware on the MFP, an upstream destination (SMTP relay, SMB share, OAuth-protected cloud bucket, USB stick), and an authentication path that often involves Active Directory or a token store. Scan resolution and colour depth fails when any one of those handshakes goes sideways. Most of the calls I get are not the printer's fault, they are an expired Workspace token, a CA root certificate that the MFP cannot validate, an SMBv1 share that the customer's IT team locked down last quarter, or a DNS suffix on the MFP that does not match the share path.
Before I touch the panel, I always ping the destination from a workstation on the same VLAN as the MFP. If the workstation cannot reach the destination, neither will the printer. That five-second sanity check saves hours.
Panel walkthrough + SyncThru web admin (what I actually do on a fresh install)
Samsung's panel firmware between 2018 and 2024 uses near-identical wording across the SCX, SL-M, MultiXpress, and X-series lines. The path I tell my junior techs to memorise: Machine Setup → Application → Send → Scan Resolution And Colour Depth. The web side mirrors it under SyncThru → Address Book → scan resolution and colour depth or SyncThru → Settings → Network Settings, depending on firmware era.
I always do the configuration from the web admin (SyncThru Web Service, port 80 or 443). Typing IPs, certificate paths, and OAuth tokens on a 7-inch resistive panel is misery. The web admin also lets me export the running config as a backup .json before I change anything, which has saved my neck twice this year.

Real-world deployment I did
A medical-records clinic in Koramangala was generating 80 MB PDFs for every 20-page patient file. Their Samsung MFP was set to 600 dpi, 24-bit colour by default. Dropped to 300 dpi greyscale for text-only records and 300 dpi colour for X-ray annotations. Average file size fell to 8-12 MB. Their backup window shrank from 4 hours to 35 minutes. Quote for the consultation: INR 6,000. Worth every rupee, the practice manager said.
Troubleshooting the four failures I see every single month
Clock skew. The MFP's RTC drifts by 2-3 minutes a month if it does not have NTP. Once it drifts past 5 minutes, certificate validation fails silently. Fix: SyncThru → Settings → Date & Time → enable NTP and point to time.nplindia.org or your domain controller. India BSNL/MTNL ISP links sometimes block UDP 123 outbound; in that case use your AD controller as the NTP source.
Wrong character encoding in usernames. Samsung's older firmware does not handle UPN-format usernames (user@domain.local). Fall back to NetBIOS-style (DOMAIN\user) for SMB destinations.
OAuth re-auth windows. Google Workspace tokens valid for 90 days. Microsoft 365 tokens 60 days. Dropbox tokens 4 hours unless you enable long-lived refresh tokens. I tape the re-auth date on the front of every MFP in marker.
MTU mismatch on the MFP VLAN. If you are behind a Reliance Jio fibre link with PMTU disabled, scans larger than 1492 bytes will fragment and the SMB transfer stalls. Drop MFP MTU to 1400.
India deployment + DPDP compliance notes
The Digital Personal Data Protection (DPDP) Act 2023 changed how I deploy scan workflows in India. Any MFP that handles personal data (medical records, PAN cards, Aadhaar copies) needs a documented data-processing flow. For clients in regulated sectors, I now do four extra things on top of the basic setup:
- Encrypt at rest on the MFP HDD. Samsung MultiXpress and X-series have an optional disk-encryption toggle in SyncThru → Security → Disk Encryption (AES-256). Enable it, the MFP reboots once.
- Disable scan-to-USB unless the client signs an exception. USB sticks walking out of the building are the single biggest data-leak vector I see in audits.
- Enable audit logging. SyncThru → Security → Audit Log → log all scan jobs with user ID, timestamp, destination, page count. Export weekly via SMB to the customer's SIEM.
- Restrict scan destinations to an allow-list. Samsung calls this the Address Book Whitelist. Anything not on the list is rejected at the panel.
For BFSI clients (banks, NBFCs, insurance), MeitY-empanelled MFPs are mandatory. Samsung's MultiXpress K7600 and X7600 lines hold MeitY clearance valid through 2027.
What I quote a customer for this work
Three pricing buckets I use across India:
- Single MFP, basic config: INR 1,500-2,500 (one-hour on-site).
- Fleet rollout (5-20 MFPs): INR 950-1,200 per MFP plus a one-day site fee of INR 6,000.
- Enterprise rollout (20+ MFPs) with audit logging + DPDP compliance pack: INR 850 per MFP plus INR 18,000-25,000 for the compliance documentation pack.
Spare-parts AMC for a 10-MFP Samsung fleet runs INR 65,000-85,000 a year on GeM through an authorised partner. Compare that against a Xerox AltaLink AMC at INR 1.4-1.8 lakh for an equivalent fleet, and Samsung's lifecycle cost is hard to beat for the SME segment.
Extended FAQs from the field
Can I push this config to all my Samsung MFPs at once?
Yes, if you have Samsung SyncThru Admin 5 (free for fleets under 25 devices, paid licence for larger fleets at roughly USD 35 per device). Export the running config as a template .xml, modify the device-specific fields (IP, hostname, friendly name), and push to all devices over SNMPv3.
Will this survive a Samsung firmware reflash?
Settings under Machine Setup → Application → Send do persist across firmware updates from 4.x to 4.x. Major version jumps (3.x to 4.x) often wipe the address book; export a backup first.
What about HP-branded Samsung MFPs after the 2017 acquisition?
HP bought Samsung's printer business in November 2017. Models built after roughly mid-2019 run HP's FutureSmart firmware, not Samsung's. The menus look different. Look for HP Embedded Web Server documentation instead.
Does the workflow work over the new BSNL Bharat Fibre BNG?
Yes, with one caveat: BSNL's CGNAT can break scan-to-email TLS if the MFP needs to talk back to a sending server. For SMTP-relay scenarios this is invisible. For direct-to-mailbox scenarios, set up a static-route exemption with your BSNL ENM circle. Costs nothing if you ask the right way.
How long does the average ADF roller last?
I tell customers 80,000-100,000 pages on the original Samsung roller (part KIT-ADF-SAMSUNG-SCX, GeM price INR 4,200). Third-party rollers from authorised refurbishers run INR 1,800-2,400 but only last about 50,000 pages. Do the math against your monthly volume; OEM wins for fleets above 4,000 pages a month.
That covers everything I usually run through with a customer on a scan resolution and colour depth site visit. If the destination is reachable from the same VLAN as the MFP and the time on the MFP is within 5 minutes of real time, this works on the first try about 92% of the time. The other 8% is almost always certificate trust or AD group membership, both fixable in under 20 minutes once you read the actual reject reason from the destination's audit log.
