Ou need to either advance (paper feeds quicker) or elay paper feed there has to be a registration adjustment

It can be as simple as adjustment of the feed wheels or some type of delay in the drum rotation
take alcohol and clean the feed rollers they may be slipping

Riso printer 390 u a01 -211 error message

I found a small sliver of a cut master inside the master feed assembly. Once it was removed, the machine worked fine. It was hard to locate,but if you remove 2 gold screws from the top of the master feeder you can gain access to the area.the screws are just below the coil springs for the master assy. lid.

Film is separated from ink roller. How do we fix? Master copy not printing.

Seems that you have mismatched the sides of the master. Are you sure you placed the master correctly? An original Riso master should have a text at the side of the roll to show where the coloured flange should be.

A05-304 error & Top section of page cutting off

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

After the riso makes a master it cuts off the top of when printed

Is this machine interfaced with the computer? if it is.. then it's nothing to do with the machine... Either it's the machine settings.. So you have selected letter size on the machine and ledger on the computer.. Something like this. The machine is probably fine..

Riso Rz 220 copies are coming out to light.

1)You can set the dencity of the riso on the controll panel before you do your masters.
2)Always use original ink.
3)If you are a bit technical you can remove the pressure roller and strip all old ink buildup from it.was it with water ann soap.
If you open the drum and take it out completely,the pressure roller is the black roller inside the machine that put directly pressure on the drum.There is only one screw to loosen and then it hooked out,but it can be tricky to hook it back if you not doing it every day.

I'm pretty sure this is a printer not a copier.

Take out the cartridge and turn it upside down, you will see a (Usually) green cylinder, does it have a ring of toner, or does it appear to have been scrathed ?
Take the copy and put it next to the drum, does the lines match? Then replace cartridge. 
If not open back and take out fuser ( two screws for cover and two screws for fuser, are the rollers o.k? replace fuser.
