TEST SIMULATION NO.67-24 PRINTER ENGINE HALFTONE AUTO ADJUSTMENT MODE COMPLETED THIS PROCEDURE.  PLEASE QUIT THIS MODE. 0 CLOSE 6) Check the color balance and density. Check to insure that the printed color balance check patch image is within the following specifications. PRINTER CALIBRATION Low density Y M C Bk Fig. 1 PG image High density A B C D E F G H I J K L M N O Max Patch A of Y, M, C, and BK are not copied. 2) Patch C or D of each of Y, C, M, Bk is very slightly copied. 1) Max. density section is not blurred. 3) Patch for each of C, M, Y, BK The patch density is identical between patches or not reversed. The patch density is changed gradually. The print density must be changed gradually from the lighter level to the darker level. The density changing direction must not be reversed. The density level of each color must be almost at the same level. Patch B may not be copied. Patch A must not be copied. c. When the PCL mode is supported: Execute SIM 64-5 to print the print test pattern. Set each set value to the default and press [EXECUTE] key. The print test pattern is printed. The print density must be changed gradually from the lighter level to the darker level. The density changing direction must not be reversed. The density level of each color must be almost at the same level. d. When the PCL mode is not supported: (In the case of GDI model) Use SIM 67-25 to print the color balance adjustment sheet and compare each process (CMY) black patch color balance and the black patch to check the color balance. The print density must be changed gradually from the lighter level to the darker level. The density changing direction must not be reversed. The density level of each color must be almost at the same level. Patch B may not be copied. Patch A must not be copied. M.

Setup and adjustment data recording Print the various setup data and the adjustment data (list) with SIM22-6 and keep the data. • In case of a memory trouble, if the data are not kept, all the adjustments must be made again. • If the data are kept, the setup values and the adjustment values can be entered without adjustments, shortening the servicing time. O. Necessary works before moving the machine 1) If the following options are installed, remove all of them from the machine. • Saddle stitch finisher • Large capacity tray 2) Remove the following consumable parts from the machine. • Paper • Toner cartridge • Development cartridge 3) Lock the following sections. • Scanner (Optical section) • Paper cassette lift plate NOTE: Since the hard disk drive is built in the machine, use care not to exert vibrations or shocks to the machine when in transit.
