A fixing fault can occur if the nip of the fixing
assembly is not correct. The machine is not equipped
with a mechanism to adjust the nip; if a fixing fault
occurs, be sure to check the nip as follows, and replace
the fixing assembly if it is not as indicated:
1) Execute 'PRINT test' under 'test mode' in service
mode to make a solid black copy on A4 or LTR
paper.
2) With the black side facing down, place the solid
black copy in the manual feed tray and make a copy
using manual feed tray.
3) Turn off the power as soon as the leading edge of
the paper appears in the delivery tray, and leave the
machine alone for about 10 sec.
4) Take out the cartridge, and remove the paper from
the pickup side as if it was a jam.
5) Measure the width of the area of glossy toner on the
paper, and see that it is as indicated in fllowing
