Magnetic media and HP 700W

[dypinc]

The user guide and HP videos says you should be able to print on magnetic media. The ones I have tried on the L360 had no feeding issues but on the 700W the feed rollers move but the media does not. I loaded the MuscleMag preset and that does the same thing with MuscleMag. Just sits there and won't move when the feed roller is moving. Even went to Input Tension 4 and vacuum 5 and that made no difference.

Something seems like it is causing it to bind like the magnetics are holding on to something. So it appears that it is not possible to run magnetic media through this printer. Anyone know why it can't when they say it should?

You can. You need to probably rather increase the tensions not lower it.
I warn you tho... Printing a lot of magnetic risks your drive roller getting bad and needing to be replaced.

I tried very 5 different combinations of input tension and it still slips. I don't think it is possible to run magnetic media in this printer. The metal that is in the feed path, especially the metal on the upper side which is on the bottom of the media is impossible not to attract the magnetic media.

IF IT WERE ME. I would pull the platen & duplicate the piece out of aluminum. No problem THEN with magnetic substrates

 

[dypinc]

The platens are plastic. That is not where the issue is.

Well I have printed magnetic just fine. But of course there is different ones out there.
Are you taking the leading edge outside or attaching to take-up? Probably can not do it from pinches.

You can try even 25 input 20 output etc.

I was pulling it out the front but will have to try adding weights or attaching to the take-up.

We print magnets on our 700w - I tried many thicknesses of media - I could only get the .020 from Magnum Magnetics to work. unfortunately we have to resort to right-angle cuts as our Graphtec cannot reliably plot this media.

 

[dypinc]

Are you guys using the curing platen covers? I have all the tension setting maxed out. I can feed forward ok with tension but backward it is no go. .020 MuscleMag

 

[balstestrat]

Did you notice there is a different backwards tension?

 

[dypinc]

Yes I noticed that. I am beginning to wonder do the media types have different pinch roller pressure?

 

[balstestrat]

No, it's always the same.

 

[dypinc]

I don't believe that is the case as there is a HP video out that states that the Fabric media setting has less pinch pressure. In a little if testing I have done so far it seams like PVC Banner may have more pitch roller pressure.

ok. really?
we did one of our roland's way back for the purpose of printing magnetic.

i assumed that was the problem

I can check but I really don't think so. The system to raise/lower the wheels is pretty basic mechanic.

Somewhere in this video the pinch roller pressure in mentioned.

Used to run magnetic on a Roland, don't know if it would relate to an HP, but we usually had to use lots of passes. If you used a low pass setting it would feed it too much at once and the rollers would slip. I've also seen posts where people tape something over any metal feed/ exit parts that were metal & holding it up, craft paper or liner paper, stating it was just enough so the magnetic material wouldn't grab as hard.

I agree.... I used to print on Roland and I was using a "table" or make something to have the material flat when feeding to avoid contact with the metal, back and front, with that, never had problems on the feed issue.

This past year I printed 50 rolls of .20 magnet on a Roland VG3 with no problems. I switched to a .30 magnet and it won't feed because the grit rollers are steel and the .30 has a greater hold strength, I now have to print mags on my Roland XR640 where the grit rollers are stainless.

 

[dypinc]

I am beginning to wonder if I got a miss-labeled roll of .020 MuscleMag.

Is the back shinny/glossy?

Does the print surface crinkle?

What I know at this point what with this magnet material what ever it is it will not feed in the 700W. It just slips on the grit roller no matter what setting are selected. What it also does it the printing surface get extremely dirty running through the print when I tested trying to feed it. It did feed and print fine with the L360. It thickness is .0185 which is another reason I question what it is. Also since there is a preset for MuscleMag Latex out there for the 700W so this should not be this much of a disaster.
