SUBJECT: Procedures to Prevent and Address E025 and Hopper Toner Overflow in the Field
This Technical Publication has been revised to add new information in page 14
GENERAL:
This Technical Publication details procedures to prevent and address E025 error codes and Hopper Toner
overflow.
DETAILS:
As this is an open investigation, HWE would like to share the information available at this time regarding
the occurrence of the E025 error code.
Toner Overflow:
Some toner bottles may contain higher than normal air pressure internally. At the time of new toner
installation the higher pressure inside the toner bottle may cause toner over flow when venting toner into the
Hopper. This excessive pressure can cause an "in rush" of toner into the Hopper, possibly causing toner
overflow around the Hopper. It can also cause an impacted Hopper as well.
This toner overflow can soil the sensors associated with the Hopper or stall the two claws "Link, Bottle
Catch", that open the toner bottle inside the Hopper, also leading to an E025 error code. This has been
reported in high altitude areas and also due to large swings in temperature. To prevent occurrence of this,
until CUSA introduces a countermeasure, follow the procedures below.
Depressurize the Toner Bottle by Pressing the Lock Shaft on the Cap
NOTE:
The following should be performed only by a qualified Service Technician (at the time of
toner installation).
altitude. Please see the detailed procedure below.
Toner scattering or "in rush" may occur when opening the toner bottle inside the copier possibly causing
sensors to become dirty. The cam HP sensor repeats detection due to dirt on the sensor which causes toner
overflow. The cam HP Sensor should detect OFF when opening the cap, however, due to toner scattering,
this sensor, mistakenly, detects ON. Even though the cap is opened, it mistakenly recognizes that the cap is
closed. (open/close detection ON, HP detection ON). The cap is repeatedly opened while the toner bottle
rotates forcing toner into the Hopper. This scenario generates a larger toner overflow.
Due to a fault in the sensors [C] [F], (see page 5) automatic removal of the toner bottle may be impossible.
