RC6300 / Utax KD60 drum blocked A4-wide

[leorebetez]

Hello,
I have a RC6300 machine (also renamed Utax KD 60) and 2 A3 drums are recognised as "A4wide". Do somebody know how to reset it in A3 mode? I found nothing in the technical documentation. Any idea about how to fix it in such old machines? Thanks!

Machine is from 1991... remove drum from machine... remove lower plastic cover under the drum handle area... should see a PCB with a row of DIP Switches... if you have a working drum compare the configuration... good luck

Hi,
Thanks for your answer. It worked!
For information (if other people meet the same problem repairing such an old risograph): It was not exactly a switch with buttons but holes in which I had to plug in the leads. The original leads had been cut. Yes, 1991 but repairing it is till now the only way for me to use a risograph. I use it mainly for elaborating non-toxic, ecologic ink for riso, and i'm starting to get good results.
Thx!
