How can I repair a GBC 4250 Laminator?

hi I fix roll laminators as a indenpendent service company around pittsburgh pa area.

is the noise like a loud CLUNK? take the film off turn the red rollers by hand hear a noise like it?

if so the red roller bearings are bad. might be hardended grease, or roller failure.

its a nasty kinda job but can be done, take lts of photos before and as you take them out.

FIRST UNPLUG MACHINE!!! remove both side covers, unplug the 2 wires that provide heater power, then take everything apart to remove the rollers and bearings.

You can try cleaning the bearings I do a bunch at a time in gasoline or use the more environmentally friendly bearing cleaner....


repack with high temp disc brake grease from a auto parts store.

let the brearings soak then try moving them, any of the bearings fall out? if so replace the roller bearng assemblies, 4 at around 10 bucks each from bearing supplier, or 400 bucks for the assembly from GBC:(

You can use regular 10 weight oil on sprockets and drive chain...

if you have any questions feel free to give me a call telephone tech support is always free.

I have been thinking of putting up some FAQs on how to fix a variety of laminators.

if anyone is around pittsburgh I still provide FREE no cost no obligation estimates.

GBCs hourly rate of $317 for the first hour within 25 miles miles of pittsburgh is just too expensive for schools these days
