Copystar cs1510 showing error e70 please help

The E70 its a troubleshooting original placement and memory errors:
1. Remove originals and replace them in the original table when the "E70" or "E71" errors display.
2. Remove originals placed on the original tray and allow the copy job from the plate to complete when the "E72" error displays.
3. Remove originals remaining in the original table when the "E90" error displays, indicating that the memory is full. Press the button with a "%" sign on it, labeled recall, to print the copies of the originals that have already been scanned. When printing completes, place the remaining originals back into the original tray and press "Start" to continue copying.

Hope helps.
