[Troubleshooting](https://knowledge.rudolphresearch.com/troubleshooting?hsLang=en) # System Crashes When Printing or After a Measurement Problem ## The instrument software crashes when attempting to print a report or when Print after every measurement is enabled. The issue may occur after an analysis is completed while the software is generating the report for printing. It can also occur when attempting to print previously saved measurement data. When a measurement is printed, the software generates the report in memory and retrieves the Windows printer settings. If the software cannot successfully obtain the required printer information, the program may crash. **Possible causes include:** - No default printer is configured. - The default network printer is unavailable. - The Windows **Print Spooler** is experiencing an issue. **Correction** ### 1. Verify the Default Printer Access the Windows Control Panel on the instrument and open **Devices and Printers**. Under **Printers**, locate the correct printer, right-click it, and set it as the default printer. If required to access Windows settings, temporarily turn off disk protection according to the instrument's service procedure. After changing the printer setting, turn disk protection back on. ### 2. Check Printer Availability If a network printer is configured as the default printer, verify that it is available and accessible from the instrument. Also check Windows for possible **Print Spooler** issues. ### 3. Collect Log Files if the Problem Continues If the system continues to crash, collect the instrument's **Log** folder for further troubleshooting. **Polarimeter:** 1. Connect a USB keyboard and mouse. 2. Insert a USB drive. 3. Navigate to **MENU \> CALIBRATION & SERVICE \> INSTRUMENT SETTINGS \> CONTROL PANEL \> WINDOWS CONTROL PANEL**. 4. If prompted to restart, select **No**. 5. Open Windows Explorer or File Explorer. 6. Navigate to `C:\Autopol`. 7. Copy the **Log** folder to the USB drive. **On a Refractometer:** 1. Connect a USB keyboard and mouse. 2. Insert a USB drive. 3. Navigate to **MENU \> SERVICE SETTINGS \> CONTROL PANEL \> WINDOWS CONTROL PANEL**. 4. If prompted to restart, select **No**. 5. Open Windows Explorer or File Explorer. 6. Navigate to `C:\Refractometer`. 7. Copy the **Log** folder or folders to the USB drive. - [Product Information](https://knowledge.rudolphresearch.com/product-information?hsLang=en#main-content) - [Autopol® Polarimeters](https://knowledge.rudolphresearch.com/product-information?hsLang=en#autopol-polarimeters) - [Density Meters](https://knowledge.rudolphresearch.com/product-information?hsLang=en#density-meters) - [Refractometers](https://knowledge.rudolphresearch.com/product-information?hsLang=en#refractometers) - [Troubleshooting](https://knowledge.rudolphresearch.com/troubleshooting?hsLang=en#main-content) - [Polarimeter](https://knowledge.rudolphresearch.com/troubleshooting?hsLang=en#polarimeter) - [AutoFlex](https://knowledge.rudolphresearch.com/troubleshooting?hsLang=en#autoflex) - [Density Meter](https://knowledge.rudolphresearch.com/troubleshooting?hsLang=en#density-meter) - [Refractometer](https://knowledge.rudolphresearch.com/troubleshooting?hsLang=en#refractometer) - [AlcoTest](https://knowledge.rudolphresearch.com/troubleshooting?hsLang=en#alcotest) - [Data Backup/Audit Trail/ Historical Data](https://knowledge.rudolphresearch.com/troubleshooting?hsLang=en#data-backup-audit-trail-historical-data) - [Pinter](https://knowledge.rudolphresearch.com/troubleshooting?hsLang=en#pinter) - [Troubleshooting - Boot Up Issue](https://knowledge.rudolphresearch.com/troubleshooting?hsLang=en#troubleshooting-boot-up-issue) - [How To](https://knowledge.rudolphresearch.com/how-to?hsLang=en#main-content) - [Density Meter](https://knowledge.rudolphresearch.com/how-to?hsLang=en#density-meter) - [Polarimeter](https://knowledge.rudolphresearch.com/how-to?hsLang=en#polarimeter) - [AlcoTest](https://knowledge.rudolphresearch.com/how-to?hsLang=en#alcotest) - [Automation](https://knowledge.rudolphresearch.com/how-to?hsLang=en#automation) - [Refractometer](https://knowledge.rudolphresearch.com/how-to?hsLang=en#refractometer) - [21CFR11](https://knowledge.rudolphresearch.com/how-to?hsLang=en#21cfr11) - [Minimum PC Specifications](https://knowledge.rudolphresearch.com/how-to?hsLang=en#minimum-pc-specifications) - [VeriLinkRx](https://knowledge.rudolphresearch.com/how-to?hsLang=en#verilinkrx) - [FAQ](https://knowledge.rudolphresearch.com/faq?hsLang=en#main-content) - [Printers](https://knowledge.rudolphresearch.com/faq?hsLang=en#printers) - [Warranty Coverage](https://knowledge.rudolphresearch.com/faq?hsLang=en#warranty-coverage) - [VeriLink Rx](https://knowledge.rudolphresearch.com/faq?hsLang=en#verilink-rx) - [Audit Trail](https://knowledge.rudolphresearch.com/faq?hsLang=en#audit-trail) - [Ports & Connections](https://knowledge.rudolphresearch.com/faq?hsLang=en#ports-connections) - [Software/Upgrades](https://knowledge.rudolphresearch.com/faq?hsLang=en#software-upgrades) - [Sample Cell](https://knowledge.rudolphresearch.com/faq?hsLang=en#sample-cell) - [AlcoTest-RI](https://knowledge.rudolphresearch.com/faq?hsLang=en#alcotest-ri) - [Quartz Control Plate (QCP)](https://knowledge.rudolphresearch.com/faq?hsLang=en#quartz-control-plate-qcp) - [Octapol](https://knowledge.rudolphresearch.com/faq?hsLang=en#octapol) - [Density](https://knowledge.rudolphresearch.com/faq?hsLang=en#density) [![RRA logo](https://knowledge.rudolphresearch.com/hs-fs/hubfs/RRA%20logo.webp?width=300&height=137&name=RRA%20logo.webp "RRA logo")](http://rudolphresearch.com) Welcome to the Rudolph Research Knowledge Base Copyright © 2026, https://rudolphresearch.com/
