Printhead Replacement Incomplete. Restart It. Previous suggestions didn't work.

[D Hook]

If I recall correctly, that series of printers also has a feature that refreshes the printheads every 24 hours or so.  I had a Z2100 that I let sit in by basement, plugged in, for about 8 months without being used and when I went to make a print, it was just fine.  Like David said, less inserting and removing, the better.  Just have to leave it plugged in and turned on.

OK Thanks.

Good Luck!

For what it's worth I think the Z3200 carriage test voltage ranges are screwed up as it gave me the roughly the following results before and after carriage PCA replacement--replaced with "new" carrriage PCA.:

"The Carriage Assembly test proceeded roughly as follows, not necessarily in this order and these words:

PCA rev. (voltage?) - 2.313    range: 0.823 to 1.005

carriage voltage - 32.41    range: 43.6-46.3"

I thought I had to replace the carriage PCA because of these results--I thought a bad MK-R head with an apparent burn mark on the nozzles had somehow burned the carriage PCA, but did not. I replaced the carriage PCA, but did not have to. I just had a bad MK-R head that caused an error on the pen voltage portion of test. It gave an 02.1??.... error or something like that.

My 24" Z3200 is working fine with the above supposedly "out of spec" voltage readings.

However, I have not had to go thru all that is posted above in relation to replacing the printheads.

I have the same problem, I found that the capacitor of the PCA burned twice. There is an electrical discharge when the printer asks to load paper for printhead calibration. I don't know what's going on, I'm investigating some short circuit but I haven't found anything so far. Could the belt tension be too high?
