Question about Riso Office Equipment & Supplies
Hi I have a T01-520 error on my Riso RN2550. I changed the colour drum over to one that has not been used in a while and now it will not work and just errors when it goes to make a master. It also will not release the drum. I have tried looking through the service manual, rotating the drum manually and holding the little release switch under the drum to unlock it and it still will not pull out and stay locked! Please help!!
Try unplugging it for 5 minutes and letting it reset, this usually works for most electronic devices that dont have a manual reset...

T01-520 is not drum stick. All the All 520 errors refer to main motor lock/ motor limit sensor faults (T01 is fault that requires maintenance). Drum error is T01-520-520. In your case 520 is the problem code, not the area code.
It is not the drum stuck, it is the main motor because there is a fault.
Replacing drum won't help , since the fault concerns the main motor.
It would be useful to know if there is an area code after 520.
Print this out, and read here how to check new Riso codes.
