When the machine is packed a protective rubber strip is inserted against
between the Glass Roller and the 4 Guide Bearings.
Pressure from the Glass Roller in transport, or when the rubber is
removed and the Glass does not fall correctly into the bearing, removes
the lubricant on the pin.
The squeaking noise is the friction between the
Guide Bearing and the metal pin it sits on, as the bearing is rotated by
the Glass Roller.
There are 4 guides in total - 2 on each side of the
Glass at the front of the machine.
Spray the Guide with WD40 or RP7 lubricant - there
is no need to undo the cover screw holding the Guide to the pin.
After spraying be sure to hold the feed button down
to rotate the Glass Roller for about 30 seconds and clean off any
overspray from the glass with rubbing alcohol [i.e. Isocol brand].
Why
does my Thermal Carrier become loose and buckle over after it's
been through the machines a few times? The cover seems to go
slower than the backing sheet and buckles over & sticks?
The machine gives out a high heat that makes the teflon
'softer' and more flexible after a few passes. This is an
important design of the carrier so a the imaging process is
not effected. Other types of plastics can 'frost' with heat
and actually distort the heat and effect imaging.
This carrier softness can cause the teflon cover to grip
less on the glass roller than that of the backing cover
sheet passing against the rubber roller. The effect is the
cover sheet bends/ buckles over as the carrier comes out the
back of the machine.
As part of operating the machine you should support the
carrier as it comes out.
When
feeding the carrier through the machine, keep pushing into
the machine until after the head grabs and comes out the
back of the machine. When the head is clear hold the head
and pull/ support it through.
By supporting the carrier you help
retain the original stiffness and eliminate this problem.
