I haven't read the standard, but according to my work experience, the original records can be handwritten or typed by machine, and the signature needs to be handwritten or stamped, not typed by machine. The following is the related content of the recording control program of ISO900 1 that I wrote in my practical work:

4.3.4 Filling, correction and change of records

4.3.4. 1 Records shall be filled in by relevant personnel and shall not be changed at will. Records should be filled in and signed in strict accordance with the relevant items, so as to be standardized, true, accurate, clear and complete. The filling person shall be responsible for every content, data and text filled in.

Generally speaking, the contents of 4.3.4.2's records cannot be changed, but they can be corrected. If it is really necessary to make corrections, it can be filled in at an appropriate position outside the original content, and the original content is crossed out (but identifiable), and finally the name of the corrector is signed.

If it is necessary to correct the archived records, 4.3.4.3 should fill in the Application Form for Document Change, which will be reviewed and approved by the original approver and submitted to relevant departments for retention and record correction.

Changes to the 4.3.4.4 Record Form shall be handled in accordance with Clause 4.3. 1.2 of this Procedure.

I hope I can help you.
