SERVICE REMARKS
C262/C265 5-2 SM
4. Master Feed Mylar Positions
When replacing or removing the thermal head, the cutter unit, the master duct, or
the guide plate of the lower master feed control roller, the strips of mylar are easily
put in the wrong position while installing the lower tension roller or lower master
feed control roller. For details, refer to "3.7.22 Master Feed Mylar Positioning".
5.1.4 PAPER FEED SECTION
1. Paper Pick-up Roller and Paper Feed Roller 1
Be careful to install the rollers the correct way around. They have a one-way clutch
inside.
2. Paper Pick-up Roller and Paper Feed Roller 2
Do not touch the surfaces of the rollers with bare hands.
5.1.5 DRUM AND DRUM DRIVE SECTION
1. Doctor Roller
Normally the doctor roller gap is not adjusted or changed. It tends to be difficult to
adjust in the field. If the gap becomes narrower, an uneven image may appear on
the prints. If it becomes wider, too much ink will be applied to the drum screens,
resulting in ink leakage from the drum.
2. Drum Master Clamper
1) Do not allow the inside of the clamping plate to become dirty with ink.
2) Do not use alcohol or other solvents to clean the inside of the clamping plate.
Use a cloth dampened with water.
3. Ink Roller Unit
Do not disassemble the ink roller unit. Each part between the front and rear side
plates of this unit has been precisely adjusted on the production line to keep the
doctor and ink rollers parallel against the drum shaft.
