Troubleshooting for remaining toner detection sensor

Take an appropriate countermeasure for the following cases:

When a message notifying the toner cartridge needs to be replaced is displayed and the cartridge is

replaced accordingly, but the message remains displayed

When a message notifying the toner cartridge needs to be replaced is displayed and the equipment

simultaneously stops its operation during the process of a job (The equipment should keep its

operation for a while even if such message is displayed.)

The Auto Supply Order function does not work.

Countermeasure

1. Check if the connector or connector pins on the toner drive are disconnected.

2. Replace the remaining toner detection sensor.

Troubleshooting when E010 paper jamming or an image failure

caused by drum separation finger staining occurs (e-STUDIO557/

657/757/857)

If E010 paper jamming or an image failure caused by drum separation finger staining occurs, take the

following measures:

Set the timing to turn on the transfer bias later by changing the value of the setting code 08-2960 in

order to improve the separation of paper from the photoconductive drum.

Set the value of the setting code 08-2960.

Refer to  P.6-62 "6.13 Transfer bias ON timing adjustment (e-STUIDIO557/657/757/857)".

As for the values of 08-2960, the transfer ability for the paper leading edge and the paper

separation ability from the photoconductor are inversely related.

Therefore, if the transfer bias ON timing is set to be too slow, depending on the environment

under which the equipment is used or the media type of the paper, the transfer ability for the

paper leading edge may slightly decrease. So, when adjusting the value, be sure to check the

paper feeding ability as well as the image quality.
