KM 4052

Hello, I have a KM 4052 that jams trying to do double sided copying, it's ok on single side. Also, after 3 sheets coming out at normal speed, the whole process slows right down, but will still work, very...……..slowly.
Attached is a list of parts swapped out.
Latest firmware uploaded, GC2-W4.

Hi, your looks more like a driver problem.


Which file do you print? Did it happen by copying as a scanner?


Here's what I recommend you set in the PCL drivers:
With these parameters the printer seems to start printing faster (therefore less time for the first print):
Preferences> Quality> Font type settings: Download fonts to the printer: image. I have also removed "use printer fonts"
Then in Printing Preferences> Finishing> Paper Layout: Productivity Priority.

But he did say copying right? Is this only happening with print jobs or also with copy jobs? Like 1 double-sided sheet original and copying it 50 times.

Hello guys thanks for the response, this is when copying.

And you changed all that stuff just because they want to print double sided with this exact machine
What's the jam code, does it jams on every one double sided page and where?

I think this machine is actually just a rebranded Lexmark. Some of those guys might have a better idea.

The problem is that the reverse solenoid doesn't click in at any point to reverse the feed gears.
