| 21 | Cannot center |
| 20 | Unable to add/remove image to imagelist |
| 19 | Bad imagelist handle |
| 18 | Unable to write disk (full?) |
| 17 | Bits per pixel either unsupported or incompatible with image type. For example, JPG requires 8 bpp. |
| 16 | TWAIN function is busy |
| 15 | User cancelled scan |
| 14 | Could not open TWAIN Data Source |
| 13 | Could not open TWAIN Source Manager |
| 12 | Could not create TWAIN parent window |
| 11 | TWAIN error (See OPCODE 9) |

| 6 | Bad OPCODE |
| 5 | Unable to allocated memory needed |
| 4 | Exceeded maximum number of open images (31) |
| 3 | Unknown image type/extension |
| 2 | Image file not found |
