Mimaki CJV30-100 Heater Fault After Power Trip

[rialine]

Hey Guys

I am looking for some assistance with my Mimaki CJV30-100.

Yesterday there was a scheduled municipal power shutdown for maintenance in our area. This morning, while the printer was in use, the power tripped unexpectedly, and I suspect there may have been a power surge through the machine.

Since then, the printer powers up normally with no error messages. It passes the internal test print, RasterLink communicates correctly, and it receives print jobs without any issues.

The problem is with the heaters. The PRE and PRINT heaters will not reach their set temperatures, while the POST heater reaches and maintains its set temperature normally. Because the PRE and PRINT heaters do not reach temperature, the printer remains on "Temperature Control – Please Wait."

As a temporary workaround, I lowered the PRE and PRINT heater settings, which allows the printer to print. However, the prints come out tacky and require extended drying time due to the lower heater temperatures.

I have already had an electrician test the wall outlet and power supply to the printer, and they confirmed there are no faults with the plug or wiring.

Any idea what could be broken blown or needing replacement before I open the machine, everything else works 100% fine.

if you are INCREDIBLY LUCKY it make just be a heater fuse.
i have next to no experience with mimaki printers, but, heating but not reaching temp could easily be that the 220 heaters are only getting 110v supplied

Hi, the voltage was checked by the electrician, so it is not a power supply issue. Thanks, I will have to take it apart and see, if anyone can guide me as to where to find the fuses? I have replaced a lot of parts on this machine over the years but never fuses, so have no idea where to start opening panels.

Ok, have located the fuses, they dont look physically damaged/burnt? How do I check if they are damaged.

go to a harbor freight, walmart or home depot and buy a cheap digital meter. (from cheapest to more expensive) probably only $10-$15
set to 220 volts ac

read across the 2 fuses . don't touch the fuses or the terminals you will get a shock

1. If the temperature does not rise to the desired temperature, and the print job has already been sent, you can force the printer to print by pressing enter.
2. If the heating element itself has burned down, then it is not necessary to look for the original one. You can buy any other one, for example, a floor one.

good point, EXCEPT not all generic heaters have the same requirekejnt for the amount of air that needs to blow across it to keep it stable.
you and i could easily do as you say, but, i would have my doubts giving this task to someone who has never changed a heater

dercar, you are assuming one of the heater coils has burned out. (generating half the heat that is required)
i am assuming a fuse has gone bad, putting 110 vac across both 220 volt coils.

Если сгорел предохранитель, то это дело 2х минут - вырвать предохранитель и запитать напрямую.
Если сгорел тен, то можно поставить совершенно любой тен (например для тёплых полов)
Деталей ситуации у чувака я не знаю
