Canon iR ADV C5051 - E0027-400

[luis1984bol]

Regards,

I had a problem with a Canon iR ADV C5051, the error E0027-004 is displayed almost every day. The user has to restart the machine every time.

I had replaced the Developing Bk unit, but after a week the error is back.

Do you have any idea about this problem?

The ADV5051 series are getting old, and as a result so too are the seals & with the pulling out/in of the Process Unit to clean/replace Drum units, the Hopper seals for the Developer Units lose their grip & over a period of time slide forward each time the Process Drawer is drawn forward until the Seal actually blocks/covers the Toner dispensing hole, which in turn deprives the Developer Unit of Toner resulting in the Error.

Remove the Process Unit, ITB Assembly & Fusing Unit (for easy access) with a good torch you will see the Seal of the offending Hopper hanging down & with a small pair of pliers grip the seal & with a backwards/forwards movement of the Toner dispensing Tube slowly (without breaking the Seal) pull the Seal towards the front of the machine - believe it or not, the Hopper does not leak excess toner & no other adjustment/settings need to be made, vacout the machine, clean Patch Detect Sensor assy & perform full Autograd.

Cost - about half an hour.

Thank you. I am going to try that.
