Sp 300 vacuum loss

[vacwsteve]

This will be good for a lugh. I bought a Roland Sp 300 in 1994 . I have maintained it meticulously , being the only user and DONT TOUCH THE MACHINE!

The last few years I have had trouble with head strikes and being unable to keep the material down on the bed to print. Real frustrating today. I am remotely located so service is a personal job , I contacted my service guy and he said I should examine the fan under the heat platen. So I did and this is what I found:



At first I thought there was aa mesh screen then you can see where I pulled some guff outta the fan.
There was so little vacuum that I was pulling the sheet down the front throughout the print ,and hanging clamped weights off it as well!

Glad to have a laugh and solve the problem.

had the same problem problem last month with a JV33; 7 years old, and the dust/overspray clogged the fans 100%! Cleaned the fans and head scrapes stopped. I've cleaned all of the JV33's now, and will continue to monitor them.

I haven't ever seen this in any manuals...

Where did you locate the fan please? I dont see it ---inside under the bottom?

Thank you,
Markus

Wonder if our 1304 has a similar fan?

MAKE SURE THE MACHINE IS UNPLUGGED.

Ya gotta take the six screws off the top of the heat platen and the front stainless cover. You should see the vacuum chamber running the length of the print run. The fan is under the chamber, off to the right a little. There are 2 screws holding it to the chamber. One is easy the other is not. Check the end flaps of the chamber as well, mine were allowing air/dust to enter the chamber as well. Good opportunity to clean out the underside area as well ,there was actual debris in mine.
Good luck!

I dunno but if it uses vacuum to hold the media down I would think there is some kind of fan involved, worth checking out.
Good luck!
