Errors should be confirmed by using the density correction test function of the maintenance utility
(2.4.1.5.4).
Countermeasures to each error are:
•
CALIBRATION ERR, DENS SENSOR ERR
Confirmation 1
When the above is displayed, check connection of the sensor cable. If the
connection is found abnormal, correct it to the normal state.
Confirmation 2
Check the surface of the sensor to confirm if it is stained by the toner,
paper dust, etc. If stained, wipe the surface neatly.
•
DENS SHUTTER ERR
Confirmation 3
Confirm adequacy of the opening and shutting of the sensor shutter by
MOTOR&CLUTCH TEST of the maintenance utility. If a malfunction is
found, replace the shutter unit.
•
DENS ID ERR
Confirmation 4
Remove the ID unit to confirm if the surface of the drum is covered with
abnormal amount of toner. Then, replace the LED head if the focus blurs
or replace the ID unit.
When a new ID unit is to be used for trial, attach a treatment device to the
ID unit lest the fuse breaks ( refer to p.132).
