Corrective actions in case of defect
H1 ON Check fuse F1 and F2 on the Generator board.

the board and to the unit. Replace the Generator
board if line voltage is present and OK.

value and types; perform a new exposure and
check if they blow again. If they blow, check, on
the Generator board, if V6 and/or V31 and V36

tubehead and Generator board. If not short
circuited, replace the tubehead.

value and type, make another exposure and, if it
will blow again, replace the Generator board.

inserted. Power off the unit and power ON it again
after few seconds; if the LED will glow again (it may
take some seconds), replace the Generator CPU
board and then the Generator board.

correct, replace the tubehead, otherwise insert it
