The SCX4623F is a rugged workhorse, but like all complex electronics, it is vulnerable to data corruption. Common causes include:
If the corruption is in the firmware itself, you must re-flash it. You will need a Windows PC and a USB A-to-B cable.
Regularly update your printer drivers to the latest version. The SCX4623F is a rugged workhorse, but like
The simplest fix is often clearing the printer's temporary memory buffer.
Sometimes the "verified corrupted data" is held in the RAM, which clears when power is fully drained. Regularly update your printer drivers to the latest version
If the printer displays a "02-000" or "04-002" error alongside the corrupted data message, check for physical paper jams or sensor blockages. Problems printing with Samsung SCX-4623F - HP Community

The SCX-4623F relies on internal flash memory and temporary RAM to process jobs. When a print job, scan buffer, or firmware setting becomes corrupted, the system crashes mid-process. If the printer displays a "02-000" or "04-002"
Perform these steps in order. More aggressive steps clear user data.
High-resolution PDFs, layered images, or large JPG files overwhelm the printer's minimal processing memory buffer.
