7.2 Cleaning rollers and sensors

Periodically, all rollers, feed wheels and sensors should be cleaned, especially if a long run

is envisaged. Use only Rubber Roller Restorer, except for the pick-up

rollers on the feed and envelope hoppers - these must be cleaned using only a

cloth dampened with water. Clean the full circumference of rubber rollers, feed wheels

and conveyors in the area of:

Feeder, folder and envelope hoppers

Insert area at the head end

Closer area at the head end

ensure the machine is switched off before cleaning rollers or sensors.
To access rollers in the insert area, raise the perspex cover and lift the green handles to

reach the paper path. Rotate rollers by hand when cleaning.
To access feeder rollers, lower the LH side cover and lift the infill cover in front of the hop-

per. Use the green knob to rotate the rollers for cleaning. Note: after a long period of time,

some inserts can cause a jam with the insert stuck between the rollers - this may especially

occur on coated material. If this happens, open the upper roller plate with the green latch

and using a cloth dampened with Rubber Roller Restorer, clean all the rollers, both upper
and lower. Use the green knob to help rotate them.

To access tower folder rollers, open the LH side covers and use the green latches to open

the daily-post hopper and paper path platten. Also open the front cover using the black

latch on the top edge.
Cleaning sensors
When cleaning the rollers, the sensors should also be cleaned by blowing away dust and de-

bris using the supplied airduster. It is important that sensors are regularly cleaned, or

operating errors may occur. Locations are shown on the following page - note that each

sensor is in two halves, receiver and transmitter. Both halves must be cleaned.
Use only non-flammable airdusters, eg part no. A0070A.
