t12-305 The master compression sensor does not go ON within 6.5 s after the master compression motor operates in the return direction.

kindly try to check your master roll and respool it. the problem could also be because your master cannot be dispose the old master properly. remove the old master and respool your master roll and initiate your machine or turn it of and turn it on again. hope to be of help.

take out the master roll look under the green plate you will see a white plasic knob, at the moment it is to the back of the machine that is the cutter unit, very carefully move it to the front of the machine until it wont move anymore. dont forget to switch off the machine, refit the master roll the problem should be resolved

I have the d17 error message. I did try to reset it but it still shows the error.

236 - incorect master roll
237 - master roll undetected
238 - master roll communication error
239 - wrong master roll detect
241 - detected a mismatch in master roll information
you must stop the machine and remove the cable from the print drum PCB and check that there is no ink on the connector or the PCB.
If there is no ink try to enter in test mode and activate 0890 test.
If it dose not work call for tech from Riso.

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.

Code D-17-236 The Riso just stop working, Why?

A D17 is incorrect master roll installed. This could be caused by a) it IS the incorrect master roll, or b) the RF tag that is inside the master roll has gone bad. Try a new one in the original packaging to help with diagnoses. Make sure they are RISO Z type master rolls specific for an RZ220.

Remove the master that is on the drum. Then check the master roll remove it cut about 18 inches off then re install master roll. hit the reset, then print bottons.
