If the cleaning material is slipping or the axis is not turning, this would indicate a gear/wheel 

is nor working and must be replaced. Order the Gears kit page 467. This error is the cause 

of the intermittent Printhead cleaning roller jam (note that the advance motor is working well, 

as the printer detects the rotation of this motor with an encoder reader placed at the back of 

the advance motor (in case the motor advance fails, a different system error would be dis-

played). 

•

In case there is still an intermittent Printhead cleaning roller jam, and the cleaning material 

does not slip, perform the following steps: 

a.

In case the printer S/N is < SG8CJ1F001, and if the white gears have not been already 

replaced, order the Gears kit page 467 and replace the white gears. 

b.

Rotate the axis of the roll anti-clockwise containing the new cleaning material, and check that 

there is not a higher friction than normal during the rotation (you should feel that, from a cer-

tain force, the ‘back force clutch’ is starting to have a slippage, maintaining a constant back 

force). 

- If you feel that there is a higher force from time to time, remove the electromechanical brake, 

and recheck again. Electromechanical brake P/N: Q6702-60683 (Printhead Cleaner Upper 

Roll Electro-brake). Replacement instructions for this part are available in the service manual. 

- Or the gears could be broken. To order and replace the (Q6702-60442 Printhead Cleaner 

Roll Driver Assembly) containing the upper and lower axis, with the upper gears (the draw-

ing in the service manual (version December ‘08, on page 312/313 is not indicating the cor-

rect part. 

c.

If there is no specific issue when rotating the upper roller, replace the encoder reader (Q6702-

60684 Printhead Cleaner Rollers encoder set) (2 off).

1.

Upper axis: turn anti-clockwise, for ¼ of a turn, the roll containing the new PH cleaning material. 

•

Release the PH cleaning roller. The roller should rotate clockwise by ¼ turn. On the picture 

below, the hand does not have any more interaction with the roller. Is it is not rotating back 

clockwise, the electromechanical breaker and the clutch/upper torque limiter has to be 

checked.

•

Note: If there is a new PH cleaning roller roll in place, as it is pretty heavy, it is possible that 

you will not feel the clockwise movement of the material once you release it by your hand. In 

this case, to confirm that there is still a ‘rewind’ pressure, just slide out the roller of the PH clean-

ing roller (after having pressed the blue part of the center of the PH cleaning roller roll) -> you
