Tightening Note:
When tightening the screw, slowly turn it counterclockwise (in the direction to loosen the
screw) with your hand until you feel that the screw is a little dropped in the hole. Then,
slightly turn it clockwise (in the direction to tighten the screw) with your hand and tighten
it according to the specified torque with a screwdriver.
Assembling Note:
- When assembling the fuser unit, make sure that the two Harnesses are placed in the
groove and under the rib of the Plastic frame. If they are not, then correct them as shown
in the figure below.
- When assembling or disassembling the fuser unit, the sponge on the HV TR top cover
might get scraped. If it is scraped, remove the scraped waste and clean the feeding path.
After replacing the fuser unit, be sure to execute the test print and check that there are no
print failures, such as vertical lines on the print result.
