HP Designjet L26500/Latex 260 Triggering Load Media Problem

[jdkrause]

We have two HP Designjet L26500/Latex 260 printers here. One is the L26500, and the other is the renamed Latex 260, the L26500 we have had since November 2013 and the Latex 260 since February 2014. They have firmware v10.0.0.7 on them. We are running Onyx RIP v11 with them.

With that said, we have had an issue with both of them since day 1. The problem is when we print something, we would get the error code 79:04 after printing; along with after finishing printing 95% of the time, both will trigger the load media menu where you select the type of media you are putting on the machine. We then switched to printing everything as a grouped job for everything we do on them to at least get what we wanted printed to print before it triggered this. We rarely get the 79:04 error anymore, but the triggering of the load media menu happens just about every time.

Does anyone have any idea as to why this keeps happening? Nothing in the firmware notes suggest a fix for this that I have seen yet. So is there a fix for it?

I appreciate any insight into this issue.

Thanks.

I have not had this error, despite running all kinds of media. What media causes this in particular? Have you cleaned the sensors? I am surprised an HP tech hasn't been able to eradicate the problem on your two machines.

We mainly run two types of vinyl, a standard Avery Gloss Vinyl and 3M IJ180C Vinyl. Sensors are cleaned. So far nobody has been able to address it.

Have you tried reloading the Firmware? I've had issues with this firmware and have had to reload it twice.

Have not tried that. When I get a little time I will give it a shot. Thanks.

Just went through that issue with our L26500. Mine was the media sensor between the roll and the platen. If you remove the feed roll and look up on the display side, you can see the switch. We put a new one in and haven't had a problem since.

If it isn't the sensor (but it most likely is) it could be the drive motor assembly for the supply shaft.

I had a similar issue on my l25500, couldn't get any tech help from the place I bought it from so I started searching and crawled under it and saw the switch that tells if there is media loaded had popped out, has happened once more and wasn't popped all the way out like the first time but came loose again, pop it back into place and off we go

The sensor is the obvious place to look, but if the spindle motor is relieving tension due to error / failure you can also get the load media issue.

Sorry, been terribly busy since the last response here. I did get some information finally after getting a tech that understood what our problem was, this was suggested to us. So we have "tweaked" the switch underneath on both machines. Things did seem fine for a while, but then then have slipped back to tripping the sensor again. So the part on both machines must be loose or there is a faulty design here. Might have to have them replaced on both machines to see if this solves it like it did for danno. Hopefully we can do this in the near future to finally put an end to this issue.

Update 2

Our switch started acting up again last week. I called HP and we were talking about how a new switch would go bad so fast. In the latest firmware, in service mode 1.3.4 sensor flip override. We enabled that and have been working flawlessly for a week now. This is still in a trial mode from what I have been told.

Interesting. You'll have to keep me/us posted on how that works out.
