C26 is a peak detection error (when the copier scans the white reference plate there is an error in the detection)
The most common cause of C26 error is the
failure the lens unit which is Toshiba's part number 6LA02100000.
The components that fail on the board are IC1
and IC10.
The board can be repaired, but most commonly it is replaced.
