Riso T11-602 code

[kyocera dave]

Any ideas please? 3700 riso machine.

T11-602 means
"The print Pressure limit sensor does not change during print pressure operation".
Where the two pressure springs hang on the bottom plate, this is the print pressure mechanism.
I would say a gear has blown in this mechanism.
Had it happen a few times!!

Thanks for your advice. Do you have a service/parts manual? Dont know the riso machines, copier engineer for 20 years!

Sorry. I cannot help you with a manual.
Good luck

V2 1995.

Seen m/c today. Error code comes up after about 30 secs from sw on. It will do a test print but print is poor. Looks like pressure roller is not in contact with drum!

Behind the power supply is the pressure control section. Look for the pressure control motor towards the top. Metal gear on pressure control motor drives plastic gear in pressure control mech. I would check that gear first.

Thanks for info. all gears are ok. Gone into service & checked "print pressure home action" & "print pressure cycle action", both have the T11-602 codes. Any ideas on resetting it?

Test mode 80 is clear error data staus. Does the pressure control motor turn at all or does it code right away?
