6.13 WHEN ABNORMAL NOISE OCCURS
When abnormal noise occurs during machine operating, identify the occurrence location, by using various OUTPUT Check. However, about the following two modules, follow the checking procedure flow.
Check the abnormal noise of the drive unit (peripheral fusing)
Check the abnormal noise when the toner is supplied or the bottle motor is driving
Because the damage or contamination of parts can lead to secondary failure, always follow the procedure.
Take particular care not to be caught in the rotating parts of the motors and/or gears.
6.13.1 PROCEDURE OF CHECKING ABNORMAL NOISE OF DRIVE UNIT (PERIPHERAL FUSING)
When the abnormal noise of drive unit (peripheral fusing) has occurred, follow the following flow, and check whether the fusing unit is the cause, by using SP1-153 (Abnormal Noise Confirmation). If the fusing unit is the cause, replace the fusing unit. If the drive module is the cause, in addition perform the operation check of various motors by using OUTPUT Check, to identify which motor is the cause.
When Abnormal Noise Occurs
About the setting value of the operation line speed in SP1-153-003
During warming-up or operating on the operation panel, the motors rotate at low line speeds. At the time, if noise occurs, start checking from [2: Low Speed]. Middle speed is for only thick paper 1 printing, so use middle speed if abnormal noise occurs when thick paper 1 is supplied.
Related SP
SP No. | SP Name | Function | Description |
SP1-153-001 | Abnormal Noise Confirmation: Unit: Execute | The fusing motor rotates with the heating control. | Fails if the fusing unit is not installed or the cover is open |
SP1-153-002 | Abnormal Noise Confirmation: No Unit: Execute | The fusing motor rotates without the fusing unit. | Fails if the fusing unit is installed or the cover is open |
