Detection timing
• During a pressure motion being performed,
the read roller sensor (PS6) output does not
change from H to L.
• During a retraction motion being performed,
the read roller sensor (PS6) output does not
change from L to H.
• During a pressure motion being performed,
the reverse roller sensor (PS7) output does
not change from H to L.
• During a retraction motion being performed,
the reverse roller sensor (PS7) output does
not change from L to H.
• The lift up upper sensor (PS16) is not turned
ON after a lapse of a given time after the lift-
up motor (M6) moves up (is turned forward).
• The glass home sensor (PS203) output
does not change from H to L after a lapse of
a given time while the original glass moving
motor (M202) is working.
• The glass home sensor (PS203) output
does not change from L to H after a lapse of
a given time while the original glass moving
motor (M202) is working.
• The lift up lower sensor (PS15) is not turned
ON after a lapse of a given time after the lift-
up motor (M6) goes down (is turned back-
ward).
• The lock signal continues to detect H during
a given time while the cooling fan (FM1) is
spinning
• The lock signal continues to detect L during
a given time while the cooling fan (FM1) is
during halts.
• EEPROM does not access normally
• The output from the CCD sensor is a prede-
termined value or less during CCD sensor
gain adjustment.
• The average output value of the CCD sen-
sor with the scanner at its standby position
is a predetermined value or more at the end
of a scan job.
• The controller of the printer control board
(PRCB) is faulty.
