The verb is common, e.g. P Tebt I. 2315 (c. B.c. 119 or 114) διὸ καὶ ἔτι καὶ viv καλῶς ποιήσεις φιλοτιμότερον προθυμηθεὶς ἵνα τὰ πρὸς αὐτὸν [. . .] διορθώσηι, “1 shall therefore be glad if you will even now endeavour more earnestly to correct your behaviour towards him” (Edd.), 7). 27" (B.C. 113) οὐδαμῶς τὰ παρὰ τὸ δέον (pap. δειον) κεχειρισμένα διωρθωμένος, ““ with no improvement whatever in your improper procedure” (Edd.), P Petr IIT. 53(4)* .. .Jatnv ἀπόστειλον πρός pe ὅπως διορθωθῆι, P Giss I. 41 τὸ (time of Hadrian) μετὰ τοῦ (2. τὸ) διορθῶσαι] κατὰ τὸ δυνατὸν τὰ ἡμέτερα.

It acquired a technical sense in book-production, where the διορθωτής was what we call a printer’s reader. Vettius Valens (p. 276) tells a story of an audacious youth who offered Euripides to ‘‘ correct” his poems, observing γράφειν ποιήματα οὐκ ἐπίσταμαι, τὰ δὲ κακῶς γραφέντα διορθοῦσθαι. The poet replied: τοιγαροῦν κακῶς γράψας... τὰ σαυτοῦ καλῶς διόρθωσον. (Note the juxtaposition of middle and active.)
