Sir,
i have Konica 7145 machine. i have any 10 mints after F-35-3 error, or some time F-35-9 eroor
Hi the error codes you are getting f-35-9 and f-35-3 are common error codes for this machine
First do not reset the machine using 25 dipswitch 3-1 until you resolve what is wrong
The errors are related to the fuser unit assembly parts
f-35-3 is the th1 thermistor
f35-9 is also an issue with th1
I can tell you that the thermistors th1 and th2 have been changed a nuber of years ago
you will need to replace them both also any other parts in the fuser like the web upper and lower clas adn rollers busings ect there is a fuser kit that you can purchase from konica it comes with all the parts to replace on the fuser unit
when replacing the parts on the fuser unit this must be done by a certified technician only
if you are not trained to do this leave it alone
The best option is to replace the fuser unit assembly and have it installed by a certified engineer you will save a lot on labour
Once the new unit or refurb unit is done you will need to switch of machine hold down 2 and 5 at the same time switch on the machine and then go into dipswitch 3-1 and change from 1 to 0
