Press and heat roller does not press each other with proper pressure .Is there any program to regulate pressure and if not how to press each lother stronger?

What kind of problem are you having? Are you running thick paper through the fuser at plain paper speed? -
How do you know it’s a pressure issue? These fuser have a pressure release motor and a sensor to detect when it’s released/engaged. The only time they don’t apply full pressure is when it’s in “envelope” mode.
One trick I was taught many years ago was to stop an A3 sky shot half was through the fuser and let it sit like that for a bit. Then take the paper out and you will have a nice shiny section where the paper has sat baking under pressure. You can then measure the width of this baked area to determine if the pressure is even across the page.
Some more information on the symptoms rather than your assumption of the cause would be useful.Comment

There are so many possibilities, I hardly know where to start.
How many prints on the current fuser?
Is the correct media type chosen, or has the temperature for that media type been changed in the System Menu?
Have the fuser temperature settings been altered in service mode?
It's very unlikely, but I had a case in which heavy fill images, would fuse poorly on the first 4 pages of each set. I'll include all the details, since this was kind-of a crazy sequence of calls:
First & second pages with heavy coverage exceeding 200% fill draw toner from the paper in two bands 35mm & 13mm toward the center of the page. The following pages pick up residual toner from the fuser, clearing up within 5 pages. The effect is worse on glossy linen "certificate" paper (97gsm), KM-4551ci. Cold areas present as chipped areas where heaviest fill is present. Hot areas present as shadow images through areas without fill. Tried IH coil, fuser, increasing fusing temperatures in U161. Temporarily enabling Silent Mode minimizes the issue. Set Plain media to Normal2 & Certificate media type to Heavy1. Remove 375W battery backup in-line with the copier. Remove additional 375W battery backup on the same line but connected to nothing. Restore U161 fuser temperature defaults.
It was the battery backups that was causing the power issue. As a desperate last attempt, I hooked up my power quality analyzer and got some seriously weird results. When I followed the power cord under a series of cubicles, I found the very inadequate battery backups.
=^..^=If you'd like a serious answer to your request:
1) demonstrate that you've read the manual
2) demonstrate that you made some attempt to fix it.
3) if you're going to ask about jams include the jam code.
4) if you're going to ask about an error code include the error code.
5) You are the person onsite. Only you can make observations.
