How to Restore Factory Defaults in Konica 7145

[eurosears]

Hi,

My dad was trying to fix my Konica 7145 and he ran in 47 mode code 93. Basically he reset the copier settings and I don't know what to enter to get it working again. Can someone please give me a list of all the things I need to enter and how to get this copier working again>? Thank you.

Try this...it sounds like he did what we used to call a "Mind Meld" and restored only part of the settings. The other sections being reset should be all it needs. Give it a try and let me know if it works. If I come up with something else I'll post.



Description

How to reset the machine, initialize memory to factory defaults.

2. Select Software SW.
3. Using the up/down arrows, scroll to address 3-4 (All Memory Reset).
4. Select OFF.
5. Power the machine OFF.
6. Enter the 47 mode (turn the machine ON, while pressing the 4 and 7 keys).

I did exactly what you stated and now I have the following every time I turn on the copier (even if I go to mode 36 and do L detect): "Please adjust L detection". I am unable to do any copies.
However, before doing what you mentioned when I was going to do L detect the value was 255, now its at 44. I should mention that my sensor on the developer is damaged (cracked) and will have to be replaced (this is why the value is below 60). However, before the factory reset even though it was damaged I was still able to do L detect and make copies once I entered the copy mode ( until the printer was turned off or jammed). SO what's with the "Please adjust L detection" even after L detect.

Also, whenever I click on anything on the display I don't hear the sound (I was able to hear it before, is it turned off). Is the sound turned off as default.

Sorry about that...I've honestly never seen the machine ask for an L-detection usually it just throws 26-3 codes. I have the Konica solutions on my other laptop and I'll be getting back to you shortly as to how to correct that problem. The key click sounds were probably defaulted off. Some machines come from the factory on some off...it's been so long since I've done an out of the box set up on a 7145 I can't remember how that was. Easy enough, though, you should be able to go into the key operator mode and turn it back on (just touch the Help key and there should be a tab at the bottom for key operator mode and once in there I believe it's under software switches). I'll be getting back to you shortly on the L-detect problem.

yeah, I get the L detect also when re-setting.. you just need to replace the developer and run an L-detect, that should take care of the problem, unless the cracked sensor is going to give you some problems

[eurosears]

Once you did the L detect in menu 36 did the message disappear and were you able to go into the copy mode ?
Its wierd that I am unable to just do the L detect in menu 36 and go into the copy mode without having this message appear. I was able to do it before.

[eurosears]

Selig67, once you turned off the copier and on and went to menu 36 and did the L-detect did it take care of it?

hi guys go to 25 next sw look for 16-3 turn it 0 and off and on the machine.that note will disapeare.

[eurosears]

That works great. Thank you. I don't even have to replace my damaged TDS.
Can you please tell me how to turn on the sound (so I can hear when I click on the buttons)?

[smiley]

hold help button and power on look for memory switch.

[eurosears]

It works now, thank you

If you know you have a bad Toner Density Sensor, do yourself, your customer and your Dealership a big favor and replace it. Does F-26 ring a bell?

I am not a dealer, I don't have any customers. The copier works fine with the damaged sensor so no reason to spend more money if the copier works fine. I will get it once I have a problem.

BTW you can turn off the F26-3 error, read above.

What does switch 16-3 actually do ? I know 3-7 turns the td sensor off but never heard of 16-3 before.

Cheers,
Mike

Well I have a cracked TDS sensor so after doing a Factory Reset of the copier I had a message that I needed to adjust the TDS sensor even after doing the L-detect.
The 16-3 took care of that message and, even better, now I don't have to do L-detect every time I get a jam or turn off/on the copier.
