C. Test Print
The copier possesses seven types of test prints, each one enabling identification of a specific
type of image fault.
If a fault on normally made copies does not occur on its respective test print, you may suspect
the original exposure system, CCD, and analog or image processor.
1. Selecting a Test Print Pattern
1) Set the copy count and copy paper size.
2) Select COPIER>TEST>PG in service mode.
3) Enter '1' to TXPH, and enter '0' to THRU.
4) Enter the TYPE number. (See Table 13-301.)
5) If you have selected TYPE=3, 4, 5, or 6, set the output color using COLOR_Y, COLOR_M,
COLOR_C, or COLOR_K. (If, for instance, you want to generate magenta, set COLOR_M to
'1'.)
6) Press the Copy Start key.
Caution:
At the end of a check using a test print, be sure to put TYPE back to '00'.
