vj1204 heaters

[printimage]

I have a vj 1204 and when i send a job it say warming up but it doesn't start printing . I would have to start it by pressing the menu key and enter. What can cause this and how to fix it?

Are you allowing time for the heaters to reach temperature?? are the heaters actually working??

Yes i can feel the heat when i touch them, sometimes i leave it for 20 mins or more and it still don't start. Before it wouldn't take so long to start printing .

Your thermistors are probably failing. They tell the printer when the heaters are up to the proper temperature. If they fail, they either give an error or just never heat up to the proper temp. You would need to replace them if they are bad. Also, if you are in a very cold environment, that could cause the same issue.

HI How do i know if it is failing? Can i test them? I am in AC but it use to work before. Do you have a part number ?

Have you tried running the test print?

If that works it might be worth trying a different print profile on the rip or checking the heater temperature on the profile you're using.

If none of these work ring "time2Maintain" Tim is a mobile Mutoh genuis and will pop and see you for a reasonable fee

Invest ~$10.00 in an infrared thermometer. Point it at the platen in various places. It will tell you what the temperature actually is. Better than a laying on of hands that, at most, will tell you that it's warmer than ambient.

I wish I'd thought of this, brill idea, you can use the same little tool used to post heat wrap

You can test the resistance (OHMS) of the thermistors and hold them between your fingers. The resistance should go up as your finger warms the metal. A better way, as stated above, is to use the infrared thermometer and read the temps of the heaters. If they get up to the proper temperature and your machine still doesn't start to print, the thermistors must be bad. If they never get up to temp, the heaters or the relays are bad. When measuring the temps, make sure you know that there are two heaters and thermistors per platen so one side may heat while the other does not.

HI Okay i will test it, i was printing a job and this is how it came out with like different colours in lines. Can this be the heaters at a high temperature?
