Ricoh D0BN IMC4500

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.

• 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.

Operation Check Procedures of the Toner Supply Motor/Toner Bottle Drive Motor

The operation check of the toner supply motor and/or toner bottle drive motor is performed by a forced toner supply, not OUTPUT Check.

• The operation check of the toner supply motor and/or toner bottle drive motor is performed by a forced toner supply, not OUTPUT Check.

1. Do [Force Tnr Supply: Exe (SP3-050-003 to 006)] for the applicable color twice. If there is enough toner in the toner supply unit, the toner bottle drive motor will not work.

   SP No.	SP Name
   SP3-050-003	Force Tnr Supply: Exe Execute: K
   SP3-050-004	Force Tnr Supply: Exe Execute: C
   SP3-050-005	Force Tnr Supply: Exe Execute: M
   SP3-050-006	Force Tnr Supply: Exe Execute: Y

2. Do [Manual ProCon :Exe Density Adjustment (SP3-011-002)] once.
   • If the operation of the toner bottle drive motor could not be checked, do step1 again after the manual execution of density adjustment.

Procedure of Checking Abnormal Noise of Drive Unit (Peripheral Fusing)

When the abnormal noise of the 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.

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.

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
SP1-153-003	Abnormal Noise Confirmation: Operation Line Speed	Line speed at the time of rotation 0: Standard speed 1: Middle speed 2: Low speed
SP1-153-004	Abnormal Noise Confirmation: Operation Time	Rotates during this time. Initial value: 60 sec.
SP1-153-005	Abnormal Noise Confirmation: Heat Center Target Temp	Temperature setting for SP1-153-001 (Unit: Execute)	Do not change
SP1-153-006	Abnormal Noise Confirmation: Heat End Target Temp	Temperature setting for SP1-153-001 (Unit: Execute)	Do not change
SP1-153-007	Abnormal Noise Confirmation: Press Target Temp	Temperature setting for SP1-153-001 (Unit: Execute)	Do not change
