[Misc] Konica c452 Scans but doesn't copy

[jmart77]

I have a Konica c452 that goes to ready, scans the original, but doesn't copy. It looks like it puts the document in a que of some sort and asks for another original but never outputs a copy. There is an oil can and L2 when pressed but the magenta IU hasn't reached the end. Any ideas.

Sounds like it's EOL. But check the contact pins for the toner and IU, I've had them bend up and cause weird issues like that.

EOL! Sounds like I need the PPLM mod. Does anyone know were/if I can get it.

If you have your indicators turned off , your transfer belt and/or fuser needs to be reset. Go into service mode, counter new release. Open the front door and reset them.

is this happening with the document feeder or on the glass....if its the glass do you get a choice of "change setting" or "finish"....go to finishing & change it from "sort" to "group"

Re: Konica c452 Scans but doesn't copy

Ok, I checked and it has a pplm mod. This machine just wont spit out a copy, all the supplies are good-- it acts like the print engine is disabled. I don't know the Konica's as well as the Toshiba's but something logic or security is keeping a copy or print job from happening.

Is there a KM tech that has seen this and can help me:

Background--new hard drive installed at customers office before I received the machine (I have since done a physical and logic format) and ran a HDD and memory check) all good.

Have you/can you print with it (e.g., from a computer)?
Have you checked the counters in service mode/any P codes in service mode?

If you just installed the hard drive you may need to "install" it - Service Mode > System 2 > HDD

You can always try a data clear and/or reflashing the firmware.

Re: Konica c452 Scans but doesn't copy

All right, cleared data, released the fuser and transport belt, checked the PPLM Mod., reset the security and administrators mode, however--it still won't make a copy. This is definitely a BizHub issue with logic or security. I've gone over what I've done and all possible errors there could be. Is there anyone out there who might be able to help me with this. I get a warning of L-2, but the Magenta IU still has a bar left, so I'm getting a reset chip next week. Can anyone provide me a way to release the L2 warning so I can prep the machine for delivery.

Does the job appear in the print queue? If so what does it say?
There is a setting in tech rep that will still stop printing even with eol firmware.
eol will show one bar left when it's reached the end

Re: Konica c452 Scans but doesn't copy

Well you cannot simply install the PPLM firmware and not change the settings and expect it to work.

There is a IU life stop setting (as mentioned, in Service Mode) and another one if you press stop-0-c in Service Mode.
Change switch switches: 51 HEX to F0 switch 55 HEX to 0C

Also, can you print to it with a computer?

Re: Konica c452 Scans but doesn't copy

This is a simple case of the magenta being at end of life, as said above check ALL the NO STOP etc settings in service mode.

The consumables status bar will NEVER go all the way full, there will always be one bar remaining.

However if you've ordered a chip that will resolve your issue.

Re: Konica c452 Scans but doesn't copy

The hex switches are set correctly. If there is another procedure under service mode-- stop 0 c-- I don't know about it please give me details. In the job que it reads stop/print for every copy I try to make-- very frustrating.

Your question was not answered, which i think is relevant in troubleshooting this problem. You asked it twice, but i did not see any reply relating to it. If the machine can print, then it will eliminate if the IU is the cause of not printing for sure and also paper size and type .

And here I was feeling feel irrelevant. (gatta love/hate emoticons)
If you press stop-0-c immediately after you enter service mode, you will get a handful of options--only one is relevant.

Re: Konica c452 Scans but doesn't copy

I am not familar with these mods that have been mentioned. The EOL and PPLM mods. Sounds like they are firmware related.
Jmart77 has spoken to me about this and I walked him through the switches.
I have not seen this machine yet.
Looks like I may get a chance soon.
I will look for another post that helped me set those switches. I think there may be another clue
in that post.

Thanks
