Konica 7255 diaplays a F56-04 code when IP is installed

Installing (adding) IP to Konica 7255 copier. When IP is installed and copier turned on, copier warms up, display works, when test sheet should print, code F56-04 is displayed (not found in service manuals).

    Yes, it is.

    We are speculating that the IP511A may be REQUIRED for the 7255. But we are still open to other theories.

    Will get back to you next week.

    We are getting a 511A (I am a copier dealer if you had not already surmised that!!)

    Thanks for your help.

    Were you able to locate any documentation that even mentions the F56 codes - we couldn't.

    We'll know next week.

    Thanks for your help - will check back when I have a confirmed answer.

    I am assuming this is the IP511 print controller?

That is correct. The IP511A is for the 7255 / 7272, and the IP511 is for the 7155 / 7165.

This is probably due to these machines using different image processing boards.

I am actually surprised it lets you get as far as you did with it.

    I looked through my stuff too, and couldn't find it. But if memory serves me right, F56 / E56 codes usually point to a image processing communication error in one way or another.

    In typical Konica fashion, It may be in the IP511A service manual itself (which I couldn't locate either).

How can I correct SC29-04 on Konica 7255?

The sensor is located on the left side of the drum cartridge it is a sensor that is covered with a white cover to the rear of the drum you must remove the drum to see it clean with cloth not a vacuum cleaner Static from vacuum can destroy it. The clear glass sensor is for paper jams! Located in the middle of the cartridge. Mite also want to know when the last 250K copies PM was done?
