HELP LOL Head issues

[PMG]

Mutoh 1204.....would a head just stop printing all together when the life span runs out? i know im due for a new head but..... the issues im having is i had a EO74rr CR2 Current error alarm at the end of a print....so i shut it down and unplugged it for a wile....when i fired it back up and went to print ,it would act as if it were printing but will not lay any ink down. i tore the machine down and looked at all the fuses and all are ok......im lost .....all the ink levels are good and lines are full and when i do a cleaning you can see ink draining...im lost

sounds like the f2 fuse on the main board

No, the counter is just that, a count of nozzle firings stored in a data base, then that hits the magic number, it just gives a warning. It is all based on MTBF analysis.

F2 fuse is probably #1 reason.
Could be the head died,
cable died or is shorting
head driver board
mother board.

Check and make sure of the f2 fuse location.

Randy from what i see on the main board is a lil white ceramic fuse about 1/16 x 1/16 square and it is on top soldered to the board...this machine is from 2006....so i dont think it will have the newer fuse setup am i correct...if what im looking at is the fuse it dont look blown. no dis coloring or broken .

These kind of fuses wont look blown, you have to measure continuity.

Yes, I think your fuses are all soldered on.
It takes a little skill and the proper soldering iron to change without causing damage to the MB.

You are welcome!
Sometimes it is tough to get on the same page long distance.
Hopefully, it is just the fuse.
