Paper Insertion Entrances - Epson LQ-870 Service Manual

REV.-A
You use the release lever to switch between friction and tractor feeding. Setting the release lever to
the friction feed position presses the paper advance roller against the platen. Setting the release lever
to the tractor feed position separates the paper advance roller from the platen and releases this pressure.
The release detector senses the current position of the release lever.

2.1.3.2 Paper Insertion Entrances

This section describes how the printer feeds paper when you use each of the paper insertion entrances.
Top paper insertion entrance
When you insert paper into the top entrance, the printer uses friction feeding to advance the paper.
The printer has two paper-out detectors: the front paper-out detector, which is in front of the printer
mechanism, and the rear paper-out detector, which is behind the printer mechanism. When you insert
paper into the top entrance, the rear detector senses when the paper runs out.
