Scan Settings provides global configuration options for OptimiDoc's document capture functionality. Administrators can configure the maximum number of concurrent OCR processing tasks and the directory used for Scan-to-OptimiDoc (Scan2OD) file ingestion.

Overview
The Scan Settings page controls system-wide parameters that affect how scanned documents are processed by OptimiDoc. These settings are particularly important for tuning performance in high-volume scanning environments.
Accessing Scan Settings
-
Log in to the OptimiDoc web interface as an administrator.
-
Click Settings in the left sidebar to open System Configuration.
-
Select the Scan tab.
Configuration Options
OCR Processing
|
Setting |
Description |
|---|---|
|
Max OCR tasks |
The maximum number of OCR (Optical Character Recognition) tasks that the scan processor runs concurrently. Range: 1–10. Default: 2. |
OCR is the most CPU-intensive part of scan processing. Increasing this value lets more scans be processed in parallel, but requires additional server resources (CPU and memory). The default of 2 suits most deployments.
Guidelines for setting Max OCR tasks:
|
Server Resources |
Recommended Value |
|---|---|
|
2 CPU cores, 4 GB RAM |
1–2 |
|
4 CPU cores, 8 GB RAM |
2–4 |
|
8+ CPU cores, 16+ GB RAM |
4–8 |
Setting this value too high relative to available resources can slow processing for all tasks. Monitor CPU and memory usage when adjusting it.
Scan2OD Directory
|
Setting |
Description |
|---|---|
|
Scan2OD directory |
The local directory path where OptimiDoc watches for incoming scan files deposited by MFP devices using the Scan-to-OptimiDoc protocol (e.g. |
The Scan2OD directory is used when MFP devices are configured to deposit scanned files directly into a folder monitored by OptimiDoc. The service monitors this directory for new files and processes each one according to the configured scan templates.
Important considerations:
-
The directory must exist and be accessible by the OptimiDoc service account.
-
Ensure sufficient disk space for temporary scan files.
-
In cluster deployments, use a shared network path accessible from all nodes, or give each node its own local Scan2OD directory with devices directed to the appropriate node.
Saving Changes
Click Save to apply the changes. Changes to Max OCR tasks take effect immediately. Changes to the Scan2OD directory may require a service restart to take effect.
Tips
-
Start with a conservative Max OCR tasks value and increase gradually while monitoring server performance.
-
If scan processing is slow during peak hours, consider increasing the value or adding a second OptimiDoc node to distribute the workload.
-
Keep the Scan2OD directory on a fast local disk (SSD recommended) for optimal scan ingestion performance.
