Orchestrator for bulk CST terminal deployment on Ricoh MFD devices. Uses the TDT API for parallel installation, configuration and uninstallation across the entire printer network — without manual access to individual devices.
V2 communicates with the terminal backend via a dedicated orchestrator on port 7312. This eliminates the "forking" of dozens of binaries and radically stabilizes execution on weaker HW.
The new scan engine uses Python asyncio. It can scan hundreds of IP addresses in
parallel without UI freezing or overwhelming the local stack.
In-depth inspection of MIB tables (RICOH Private MIB). Automatically detects serial numbers, models, toner statuses, and installation readiness without physical access.
Request pacing with random jitter reduces the risk of port scan detection in the customer's IPS/IDS systems.
Real-time log tailing directly in the UI. See exactly what is happening inside the installer without needing to search for temporary files on the disk.
The installation process is split into stages: Pre-check → Binary push → Configure → Verify. Each step has its own retry logic and error handling.
The app starts with full Network Scan and Deep Scan capability even without TDT components (java, lib). Ideal for quick device diagnostics at a customer site without the full deployment package.

How CST V2 runs deployment
Asynchronous SNMP probe verifies the model, serial number, and device readiness (not in deep sleep, no critical errors).
Secure transfer of the installer via local API to the device's HTTPS port. Uses parallel execution for batch operations.
Connecting the terminal to the specified tenant, setting certificates and card reader parameters according to the selected profile.
Final check of application status and device restart after configuration completion.
Security Measures
Intelligent pacing and jitter for IDS/IPS-friendly scanning.
Automatic masking of sensitive data (passwords, keys) in logs.
Detailed tracking of every operation for later security auditing.
No temporary files, everything runs from a fixed controlled folder.
Mandatory certificate validation when communicating with the Cloud portal.
Automatic preference for modern ports over dangerous fallback options.
Build includes an SHA256 manifest for easy onboarding into corporate EDR systems.
CST V2 is not just a script. It is a deterministic orchestrator designed for stability in conservative enterprise environments.
%TEMP%, which significantly reduces false-positive risk in
SentinelOne/CrowdStrike.On-site deployment — bulk, repeatable, and significantly faster than manual procedures.
Bulk configuration management, reliable reporting, and diagnostics of the entire printer fleet.
Safe network mode, automatic masking of sensitive data in logs, EDR-friendly operation (one Java API server instead of hundreds of subprocesses), and SHA256 manifest for AV/EDR allowlisting.
All binary files and libraries (CST_Installer_V2.exe, lib, java, data) must remain in the same root folder as the Terminal Deployment Tool (TDT) to preserve paths to the API backend.
For proper functionality of the CST terminal on Ricoh devices, it is essential that the devices are pre-added to the appropriate CST Tenant/Cloud portal under the correct serial number.
Always distribute the generated
SHA256SUMS.txt file alongside the build. Administrators at the target site must
verify the package integrity against this manifest prior to execution.
