That is the master clamper area. Take off the rear cover. From the rear it is on the right. There is a motor and a rack gear that moves to open the drum master clamper when removing and loading a master. With the back cover removed, try to make a master while watching that assembly. You can also put the drum in and drive the motor by hand to watch and see if opens the drum clamper.
Booster is okay, you have to bench bleed the MC, first. So, since it is installed, bleed it with a kit from the parts store, little plastic hoses screw in to the brake hose fittings, and put other end under fluid in reservoir. pump slowly, especially wait at end of release, for fluid to refill piston chamber....pump until no bubbles...
FROM THIS POINT you must not allow fluid in reservoir to go low, or start all over again....
Now bleed the brakes and you will eventually get pressure.
First, bleed the master cylinder. You do this by loosening the line nut on the output end of the master cylinder, press the foot pedal until it sinks all the way down, tighten the nut, release the pedal. Continue to do this in this EXACT sequence until all the air is out of the master cylinder.
Then using the EXACT sequence, bleed the rear brake caliper or the rear wheel cylinder. If your bike is equipped with drum brakes, you'll have to adjust the brake shoes to the drum.
Very important, DO NOT ALLOW THE MASTER CYLINDER TO RUN DRY DURING THE BLEEDING PROCESS. Make sure that the small hole in the bottom of the master cylinder is clear.
We had the same problem in that once master was done, it did not print. We tried this solution.
Machine must be off. Top right hand corner the and - buttons with arrows on (to align your print either left or right) press these down simultaneously. While holding them switch machine on.
A number 203 will appear on your screen.
Release hold on buttons Press 101 on number board you will hear machine inking master. Allow it to run until complete.
Hope this helps.

the thing might be down to an old master stuck to the drum this could cause the faint copies and the missing print.. pull the drum out check under the master.this would also cause the paper to jam on exit. the error is for no master eject check the calmp is free where it grips the master and also the path for the master eject to the waste bin
Hi, The correct master cylinder may still be the one you have, you will have to have it checked by a brake specialist or reputable parts supplier, to make sure there is no line pressure valve in the front brake section of master cylinder. On some of the more common early Master Cylinders it was just a matter of removing valve and discarding it. Hope this is helpful. Regards March
