63 07 SPF/RSPF automatic correction
Used to adjust the SPF/RSPF white correction start pixel position.
When the carriage or the platen glass is replace, this simulation must be executed.
When this simulation is executed, the initial window as shown below is displayed.
When [OK] key or [START] key is pressed with the OC cover open, the automatic adjustment is executed
and the position (which pixel from the CCD edge) of the exposure correction sheet (white Mylar) in the SPF/
RSPF position is displayed.
After completion of adjustment, the result is saved to the EEPROM.
When the result is in the range of 93 - 299, it is judged as a success. If not, it is judged as an error. In case
of an error, the result is not saved to the EEPROM.

WHITE ADJUST
* Since this simulation detects the border line between the white Mylar (white) edge and the sky-shot
(black), if the simulation is executed with the SPF/RSPF unit (OC cover) open, it is judged as an error.
* Since the adjustment value is the position of the border line, in order to execute white correction in an
actual SPF/RSPF copy, the point is "Adjustment value - 34th pixel."
64 01 Self print
Used to perform printing of one page disregarding the optical system status. Also when the print command
is issued from the host, printing is performed.
When this simulation is executed, warm-up is performed and the ready lamp is lighted. (Since, however, the
optical system is invalid, initializing is not performed.)
There are following four self-printable patterns.Use numeric keys to select a pattern.
The selected pattern is displayed on 7-segment LED.

(*1) After outputting 1 line black data, white data of 2 line is outputted.
(*2) The grid pattern of about 1cm square is outputted.
(*3) Data are always made for A3 size. If printing is made on paper smaller than A3, the remaining data are
not outputted. (Images are not formed on the drum.)
