LQ-2070 Service Manual Operating Principles 2.1.4.2. Paper Advance Mechanism This section describes how the friction and tractor advance mechanisms work to move the paper through the printer. 1. Friction Advance Method Paper is held between the platen and the paper guide rollers and between the paper tension roller and paper tension unit cover. The paper feed (PF) motor pinion gear, turns in the direction of the black arrow, driving the paper advance reduction gear. The paper advance reduction gear turns the platen gear and paper tension roller gear. Paper advances in the direction of the white arrow. Figure 2-5 shows the friction advance method when paper is fed through the top paper entrance. In the friction advance method, the paper guide roller spring holds the paper against the platen. Paper can be released by setting the release lever to the tractor feed position. Figure 2-5 Friction Advance Operation Using the Top Entrance Rev.A 2-5

2.1.4.2. Paper Advance Mechanism
This section describes how the friction and tractor advance mechanisms work to move the paper through the
printer.
1. Friction Advance Method
Paper is held between the platen and the paper guide rollers and between the paper tension roller and paper
tension unit cover. The paper feed (PF) motor pinion gear, turns in the direction of the black arrow, driving
the paper advance reduction gear. The paper advance reduction gear turns the platen gear and paper tension
roller gear. Paper advances in the direction of the white arrow. Figure 2-5 shows the friction advance method
when paper is fed through the top paper entrance.
In the friction advance method, the paper guide roller spring holds the paper against the platen. Paper can be
released by setting the release lever to the tractor feed position.
