Platen-open mechanism
The platen-open mechanism is used for the following purposes:
• Paper loading when using the printer with the curved path type. (Excluding when
using semi-autoloading mode.)
• Removing a paper jam when the paper jam has occurred
• The thermal head and the platen cleaning
The mechanism consists of the frame, platen, the lever, platen, the shaft, platen, the spring,
lever, the lock lever, the spring, lock lever, and the pushplate, platen, B.
In the frame, platen, the platen is mounted. The lever, platen is operated by hand to open the
frame platen unit. The shaft, platen connects the lever, platen and the frame, platen to the
frame, base in a manner which allows them to rotate. The spring, lever pulls the lever,
platen in the opposite direction of arrow A when the platen is open. The lock lever is located
on the gear train side of the frame, platen and locks the frame platen unit to the frame, base.
The spring, lock lever (inside the lock lever) pushes the lock lever back. The pushplate,
platen, B is secured on top of the frame, platen and covers the fixed blade.
When the frame platen unit is closed, the platen is in the print-ready position where the gear,
platen and the gear, idler are engaged and the power can be transmitted readily. Also, the
lock lever is locked at a part of the frame, base to prevent the gears from disengaging.
To open the platen, turn the lever, platen in the direction of arrow A as shown in Figure 2-6.
Simultaneously, the lock lever is released and the frame platen unit is opened. To close the
platen, turn the lever, platen in the opposite direction of arrow A until the lever stops.
