Subject: [Digital BW] Cutting problem on LF (7500) printer


Hello,
Has anyone the same problem when printing on 300gr+ paper as I
have?
I print on PhotoRag rollpaper 308gr and my 7500 can't cut through
the paper. This is very frustrating and I can't see any cutting
adjustment for paperthickness in servicemanual either. Any
solution
to make the printer do it, or is the knife only made to cut thin
office paper?

Regards

Soren,

Don't use the cutter for that paper quality, it was never
intended for such forces and the head carriage will suffer in the
end.
I have removed the knives of both my 9000's to be sure that the
head traction units never endure that stress.

Soren,

Epson didn't have that paper quality when the 7500 was launched I
guess. Anyway I just don't trust a traction construction that is
made to lay down 720 droplets per inch in two directions when it
also has to cut paper of 310 gr/m2. Not thinking of the dust and
lint buildup near the printing area that is caused by the auto
cutting as well.

Try to find carton tubes that are used for packaging. Diameter
5-6", wall thickness approx. 1/5". Length like the widest you can
print. Attach a sheet of paper to it that can go round the tube
twice. Use tape at both sides of the hinge. The crosscut of that
tube is then like a Q with a long tail.
On the floor I have a roller bar where the tube rests on. When
the printed paper touches the floor I slip it between the
attached sheet and the tube and roll it up so the curl in the
printed paper is reversed, when the job is finished and I need
the print right away I give the paper some slack with the paper
forward button and cut it along the underside of the stainless
steel cover of the 9000. If that isn't possible on the 7500 then
you could add a metal profil to the roller bar to do the same.
The roller bar can be quite simple and it even doesn't have to be
a true roller bar,
two fixed PVC sewer pipes of 2" wide at 5" distance from one
another will do the trick as well but rolling the tube takes a
bit more force.
When a complete roll of 40' is printed it is far easier to handle
than sheets this way, put the finished roll somewhere out of the
way and leave the prints on the roll to flatten the old curl. Put
it on the same roller bar or another to cut it with the board
cutter like I do. There's a small 'round cartonnage' factory in a
town nearby that made about a 100 tubes on order, quite cheap
when they already have another order for bigger runs. I also use
the tubes for print transport but then they go inside :-)
