Hello all
The thermal head in my Riso MZ790U recently started playing up. The machine has been making prints with a 5mm band
of information missing in the middle of the paper (see attached image). I've tried resetting the machine and cleaning the
TPH - but neither helped solve the problem.
So, I am going to replace the TPH unit in the MZ - but I wonder if anyone here could give me some pointers on things to watch
for/be careful about when doing this. I understand that I will need to adjust the ohms when I install the new unit - anyone
have any ideas about how to do this?
Any help would be much appreciated!!
best
Duncan
