4.3 DETAILED DESCRIPTION OF

MAINTENANCE-MODE FUNCTIONS

4.3.1 Setting of the scanning compensation parameters stored in the EEPROM (involving home

positioning of the copyboard screen) [Function code 55]

nn Function

The machine performs home-positioning of the copyboard screen (using black HP marks on the

screen) and sets the scanning compensation parameters registered in the EEPROM.

nn Operating Procedure

(1) Open the paper compartment cover and hold down the COPY ALL and FEED keys for 15

seconds.

(2) Press the COPY ALL key with the paper compartment cover opened.

The machine checks whether either of the two black HP marks on the copyboard screen is

placed in the home position (i.e. in the scanning position). If neither mark is in the home

position, the machine scrolls up the copyboard screen until either mark comes to the home

position.

After detection of either black HP mark, the machine flashes the PAPER LED and starts

setting the scanning compensation parameters in the EEPROM.

Upon completion of parameter setting, the machine turns the PAPER LED off and returns to

the regular operation mode.

If any error occurs during this procedure, the machine prints out an error code and returns to

the regular operation mode.
