Lanier error code 00


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.

How do i remove jammed master in disposal unit in a riso gr3770?


On the back there is a box where the masters are used, remove and check for any play between the master and the shipping box. Open trough the green lever the lid covering the box used masters and check the part that carries the master used for the box, if there pieces or entire master mired in this piece. Let her go trough the alavacas extremities. Make sure the drum is with the clamp without damage, because it holds and releases the master of the carregamanto and unloading of master. Remember these tips without seeing the machine and if you have knowledge of the equipment inside are a little difficult, but be able to get there. I hope I helped you.

My Risograph CR1610EP will not make a master. I can hear it remove the old master. The JAM indicator comes on and the number 2 in the center of the drum. There is no master (old or new) on the drum.


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.

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

Your problem is with you clamping unit which is responsible for put the master on to the drum. Please check the unit for any phycial damage. You can also remove the old master on the drum your self and place back the drum into the machine and try asking the machine to make a new master. Good luck.
