E077 Error Mutoh 1614 Left hand side of the platen is on all the time

There’s a heater controller board under the front platen which is prone to failure. Most likely one of the relays has packed up. You can replace the individual relay from memory but I’ve only ever just replaced the board.

Thanks I’ll look into that. Luckily it is a quiet week for us so I should have time to have a play with it.

Exactly the same thing happened to me recently. I replaced the heater relay board. Cost £320 from digiprint supplies. Managed to fit myself and it fixed the problem!

Be careful…I had some paper inserted and it almost caught fire it was so hot.

hi there
I received the new board today. I bought it from the guy who sold us the printer in the first place (Alex).
Fitted it and turned it on. Error 76 pre-heater after 30 secs to a min. This had happened with the old board after i had started this thread.

Alex suggested turning off all the heaters to test.
while doing that it came up e078 afterheat (had to restart it)
then e077 platen heat (had to restart it)
then e079 err commu (had to restart it)
then e078 again (had to restart it)
finally got the heaters turned off and it stayed on.

put the heaters back to pre heat-35, platen 35, and post heat 42, and all the 76 pre heat error is back.

Alex is suggesting an update to the firmware.
Do you think he is on the right track?

We updated the firmware of the heater controller but it is still faulty.
Without the heaters turned on we have a printer that works.
Turn any heater on and it warms up and then throws an error 76, 77, 78, depending on the heater.
It has once had an error 79 "err commu" but only that one time.
Any ideas?
