A multifunction device can be a storage system, network appliance, email client, scanner, address book, and print server in one box. That is why a printer can matter to CMMC scope even though nobody thinks of it as a 'computer.' If CUI is printed, scanned, cached, queued, emailed, or retained by the device, the workflow deserves the same deliberate analysis as other data paths.
The simplest approach for many small contractors is not to harden every office printer. It is to designate a small number of approved devices for CUI workflows, restrict their functions, and prohibit sensitive use on general-purpose equipment.
Map what the device can store or transmit
Review the model's capabilities: internal drive or flash storage, retained print jobs, scan-to-email, scan-to-folder, cloud connectors, fax, address book, remote administration, firmware updates, and audit logging. A feature that is never intended to be used can still create risk if it is enabled by default.
Document which functions are allowed for the CUI workflow and disable unnecessary ones. The configuration baseline should be tied to the exact model or device class because consumer printers and enterprise MFDs can have very different security capabilities.
Harden the administrative surface
Change default administrator credentials, restrict the management interface to approved networks and administrators, disable insecure protocols, keep firmware current, and review SNMP or discovery settings. If the device supports role-based access or secure-release printing, decide whether those controls are appropriate for the environment.
Keep a configuration record and sample it periodically. Printers are often omitted from vulnerability and patch processes because they are owned by facilities rather than IT. Assign a named technical owner so firmware and access settings do not become nobody's responsibility.
Control scan and print destinations
Scan-to-email can send CUI through a mail system that was never intended to handle it. Scan-to-cloud features can create an unapproved SaaS copy. Address books can retain external recipients. Restrict destinations to the approved environment and disable consumer cloud connectors where they are not needed.
For printing, use secure-release or controlled output where practical, especially in shared offices. A page sitting in an open tray is no longer protected by disk encryption or network segmentation. The physical workflow begins the moment paper leaves the device.
Treat paper as part of the system process
Define where printed CUI can be stored, who can access it, how it is transported, and how it is destroyed. Locked cabinets, clean-desk practices, visitor control, and approved shredding may be more important to this workflow than another network control.
Make the procedure specific. Employees should know whether they may carry pages home, leave them in a conference room, or use an ordinary recycling bin. Broad wording such as 'protect sensitive documents' leads to inconsistent behavior and weak evidence.
Plan maintenance and disposal before the device fails
Service technicians may replace drives, take components off-site, or use vendor support accounts. Contract or service terms should address access and media handling for devices used with CUI. Keep a record of maintenance that affects storage or security configuration.
Before retirement, sanitize or destroy storage according to the organization's approved method and retain evidence of the action. A leased MFD being returned to a vendor can be a data-disposal event, not simply an asset-management event.
Reduce scope with designated devices
Choose a small approved fleet for sensitive work, place it inside the controlled environment, restrict access, and clearly label the workflow for users. Configure endpoints so CUI jobs cannot be sent to general office printers where practical. This turns a large ambiguous printer estate into a manageable set of known assets.
Review the approved devices in the asset inventory and SSP just like other in-scope technology. At least annually, confirm firmware, admin access, storage settings, scan destinations, maintenance arrangements, and physical controls. Printers become much easier to defend when they are treated as systems instead of furniture.
What to put in the printer asset record
Record device ID, model, location, owner, firmware version, network zone, administrative interface, approved users or groups, internal storage, enabled print and scan functions, approved destinations, logging capability, maintenance provider, and sanitization method. Add a short scoping rationale that explains whether and how the device participates in the CUI workflow.
Keep the configuration baseline separate from one-time screenshots. The baseline states what should be enabled or disabled; periodic evidence shows the current device matches it. This makes firmware replacement or device swap easier because the expected security state is already defined.
Track consumables and paper handling only where they affect the controlled workflow. Do not turn facilities management into a compliance bureaucracy. Focus on where CUI can be left, copied, removed, or exposed, and on the storage media inside the device itself.
When a device is leased, add contract-end handling to the record. Know who owns the drive, whether the vendor removes it, how sanitization is verified, and what happens if the printer fails mid-contract. Disposal planning is easier before the truck arrives to collect the unit.
Include print and scan failures in incident handling. A misdirected scan, abandoned CUI print job, lost paper packet, or device returned to a leasing company with storage intact can be a security event even though no workstation was compromised. Employees should know who to contact and how to preserve relevant facts such as time, destination, device ID, and affected documents.
During an assessment rehearsal, follow one page from print command to destruction. Verify the endpoint is permitted to print, the selected device is approved, secure release or access control works as designed, the output is collected promptly, temporary copies or scan destinations are controlled, and the final paper disposal process is available. This simple walkthrough tests technical and physical safeguards together.
Assign responsibility for firmware and security review during procurement, not after installation. New devices should be checked for storage, management protocols, cloud connectors, default credentials, and secure-release capability before they are approved for sensitive work. That prevents facilities from introducing a feature-rich MFD into the enclave with every convenience function enabled and no technical owner prepared to maintain it.
Plan the end of the device's life at procurement time too. Leased MFDs can leave the site with internal storage, address books, cached jobs, scan histories, or configuration data. Define who authorizes return or disposal, how storage is sanitized or removed, what evidence the service provider supplies, and how the asset inventory is closed. Secure operation for three years can be undone by an uncontrolled lease return on the final day.
