Re: EPSON 1400 + MIS UT-14, Pizza Wheel marks...

2012-08-22 by jffelinik

Okay,

Things took another turn here as I decided to go more scientific with my "project".

After finding out that, yes, there was some banding at the last portion of the papers after a certain level of shimming, obviously, as that is when the feeding is done by the pizza's that I had been manipulating with.

So in order to have a clue about when this started to happen, I decided to:

- Put back ALL wheels again
- Remove the current scotch-shims

And start all over again.

Now this is where my brain for some reason rebooted, thank gods, and I decided to have a look at how the 1400 handles different paper weights.... The EPSON documentation about this is to the least said P*SS-poor, so I googled, and found that apparently on this model, it sets the platen gab automatically. Apparently in another/older driver, or maybe on windows only (I am on OS X) this should be possible to set, but not in my system. So I googled up all the paper selections I have, and came to this list:


Ultra Glossy Photo Paper:			305 		gsm
Premium Glossy Photo Paper:		250-255	gsm
Premium Semi Gloss Photo Paper:	251		gsm
Glossy Photo Paper:				225		gsm	
Archival Matte:					192		gsm
Matte:						102		gsm
Photo Quality Inkjet Paper:		102		gsm
Photo Stickers:					180		gsm
Envelopes:					75-90	gsm


And in my case, everything should be just fine using the 305 gsm paper setting, Ultra Glossy etc.

So I printed a sheet this morning, and it was of course the best so far... It does exhibit a tiny bunch of pizza trails, but not even close to what I've had before, and I can't wait until tomorrow when the print is dry to see if they're still around...

Anyway, should tomorrow show some trails, now at least I know that I only need to shim a tiny bit, based on information found here:

http://www.paper-paper.com/weight.html

So I have some transparent film which is 0,1 mm thick, and this gives me a clue about how much I actually shim should I decide to do so tomorrow.


Hopefully end of journey, I'll be back!



Cheers
J.F. Felinik, still on my way to get a used 7600 anyway (as I've found one dirt cheap)...
