Fuser temperature setting 2330c

[Alastair38]

The printer is printing on 250gm card, custom size, which is being creased after printing. The toner flakes off a bit when it is being creased. I know this is a familiar issue with laser printing, but I'm wondering if I can reduce the flaking by increasing the fuser temperature on the thick 4 setting only. The paper is usually about A3 size. I'm not exactly clear on which setting is the right one to adjust, just: 5277-3 or some of the others too? And is it wise to go as high as 16 on the settings (200'C)? or is there a heat after which if you go higher it causes problems?

Are you sure the fuser pressure screws are not backed out? that used to be done to increase service life of the fuser
