3.1.4 LASER UNIT
1. Do not loosen or adjust the screws securing the LD drive board on the LD unit.
Doing so will throw the LD unit out of adjustment.
2. Do not adjust the variable resistors on the LD unit. These are adjusted at the
factory.
3. The polygonal mirror and F-theta lens are very sensitive to dust.
4. Do not touch the toner shield glass or the surface of the polygonal mirror with
bare hands.
3.1.5 FUSING UNIT
1. After installing the fusing thermistor, make sure that it is in contact with the hot
roller and that the roller can rotate freely.
2. Be careful to avoid damage to the hot roller stripper pawls and their tension
springs.
3. Do not touch the fusing lamp and rollers with bare hands.
4. Make sure that the fusing lamp is positioned correctly and that it does not touch
the inner surface of the hot roller.
3.1.6 PAPER FEED
1. Do not touch the surface of the paper feed rollers.
2. To avoid misfeeds, the side and end fences in each paper tray must be
positioned correctly so as to align with the actual paper size.
3.1.7 IMPORTANT
1. After installing a new PCU, you must run SP2-214 to initialize the TD sensor.
After starting initialization, be sure to wait for it to reach completion (wait for the
motor to stop) before re-opening the front cover or turning off the main switch.
2. If the optional tray heater or optics anti-condensation heater is installed, keep
the copier's power cord plugged in even while the main switch is off, so that the
heater(s) remain energized.
