4. for the drum scanning instrument, drawing adorn the bad holding paper that is easy to generate, especially for shabby drawing, fragile drawing causes irrecoverable loss.
5. greater than large format drum scanning instrument, because drawing thickness difference, fineness difference (coefficient of friction difference) so chart drive speed is not quite similar when the air roll rotating speed is identical, causes the drum scanning instrument to have certain error.
6. because cost an arm and a leg and the attribute of precision instrument,, limited more people and grasped the graph scanning technology so large format drum scanning instrument needs special messenger's keeping to use.
